    As I made my way home today, I watched a woman on the subway platform reprimand another for wearing a surgical mask. “Shame on you,” she said. “There are people who need those. Shame on you.”

    As the mask-wearing woman stumbled away from her aggressor, I couldn’t help but reflect on where we – the global “we” – are right now. Yes, surgical masks are in short supply, and our frontline healthcare workers are those in need. Wearing a mask as prevention against a virus that is not airborne simply serves as a flimsy barrier to keep your hand from reaching two of the three avenues of infection – the mouth and nose – and the general public can remain healthy without them. 

    But now is also not the time to bare our teeth. The present COVID-19 pandemic is a fight – that of microbe against the people. Shame on us, then, to turn it into people against the people.

    As humanity, we are a collective. We have a responsibly to one another to remain a collective through support, through public health education, and imperatively, through access to resources for all.

    On my same trip home, I heard a man tell his friend how in the grocery store a woman took all of the baby formula available and would not share with another costumer, even when begged.

    We’ve fashioned our world into one with near unlimited resources, and near unlimited access to them. What we are now seeing is movement toward survival of those with means. And this reality rears its ugliest head when we act selfishly.

    While we must practice social separation for the sake of our collective health, we must remember not to separate ourselves from the tenets that unite a prosperous humanity – those of promoting the common good, and the betterment of the world through help, especially when times are grim.

    What happens when our crisis invades those of lesser means, of poorer healthcare? If we cannot act with a moral conscience now, then when? Faced with fear, this global pandemic has turned many of us inward. But now is the time where we must act ever more outward.

    The only way to heal our population is with a collective push toward the good of one another, sibling and stranger alike. As more continue to fall ill world-wide, and as over-saturated healthcare systems are forced to prioritize the treatment of one over another, we must lend ourselves to collaborative support, so that the work of the front line is not in vain.

    From simply staying home if we feel ill to washing our hands for the sake of us all, there is no act too small. But in not doing what we can, however little, we neglect our neighbour. And in using aggression, in refusing to share, we fail.

    These are dire times, but we can all play a role in our healing. There is only one humanity. If we let one another fall, we all fall.

    The 2019 novel coronavirus (2019n-CoV), like MERS and SARS, belongs to a family called coronaviruses that may be amenable to an approach to create a single vaccine effective against several infectious diseases.

    Historically, vaccines have been developed by isolating, inactivating, and injecting viruses, bacteria or pieces thereof into the body to stimulate an immune response.

    Recently, a more rational design approach has enabled the design of new candidate vaccines with high precision. It’s a potential game changer in vaccine development.

    A group of researchers in the United States is using synthetic biology tools to develop a universal coronavirus vaccine. Using these tools, scientists redesign and construct artificial organisms to develop new abilities. They manipulate strands of DNA, insert them into an organism's genome, and create a new artificial DNA molecule designed for specific purposes.

    Before they begin working with DNA, scientists at the University of Washington's Institute for Protein Design use a computer program to develop new vaccines against several viruses, including coronavirus. This technology allows them to design new vaccine candidates from scratch, including coronavirus antigens. These antigens are recognized by the human immune system, which then produces antibodies to help the body fight off the invader. When used in a vaccine, these antigens stimulate the body to create immunity to the disease.

    Coronaviruses (CoV) are a large group of viruses that can infect humans and cause respiratory illness with a wide range of symptoms, ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). The 2019 novel coronavirus (2019n-CoV) causes an infectious disease called COVID-19.

    This highly contagious disease has been declared a global pandemic disease by the World Health Organization (WHO). Although COVID-19 has a low mortality rate, meaning that most cases are mild, it spreads easily, so the minority of cases that are severe can still easily overwhelm health care systems.

    To add perspective, the MERS virus has the highest mortality rate. One of three people infected die, typically because of a respiratory illness. However, it has a low transmission rate and since 2012, there have been about 2,500 cases worldwide. It is a lethal virus but doesn’t ostensibly spread to person-to-person. On the other hand, SARS virus is less deadly than MERS with a mortality rate of around 10 per cent, but much more contagious than MERS. Back in 2003, there were about 8,000 cases of SARS and about 800 deaths worldwide.

    One of the worst pandemics in recent history was the 1918 Spanish flu, which killed about two to three per cent of its victims, or at least 50 million people worldwide. COVID-19 mortality has been estimated to be around 1.6 per cent. This disease has many similarities with influenza, since both are contagious diseases with low mortality rates. However, mortality for COVID-19 appears higher than the 2009 H1N1 pandemic that killed around a tenth of a per cent of affected people worldwide.

    One hundred years after the Spanish flu, the world is a much more populous and different place. We are much more prepared for infectious diseases, but we are able to connect to each other around the world within hours via air travel making disease transmission easy and control of these diseases globally challenging.

    The University of Washington researchers believe the new approach combining computational modeling and synthetic biology will help develop effective vaccines against all three coronaviruses, including SARS-CoV, MERS-CoV, and 2019n-CoV.

    Using this strategy, scientists attached coronavirus-specific antigens to a spherical protein nanoparticle that looks like a virus to the body’s immune system, and as such stimulates antibody responses. These nanoparticles are now being tested in mice to evaluate immune responses in vivo.

    The main advantages of having a nanoparticle as the core of a vaccine is that it can be used to boost immune responses and can be designed to include antigens from several viruses. This makes one vaccine capable of fighting multiple infectious diseases. It also makes the vaccine tolerant of heat, reducing the need for refrigeration - a great feature for vaccines that are used in tropical resource-poor countries.

    Synthetic biology may offer a universal coronavirus vaccine that can be quickly modified to combat future mutated strains, but such vaccines remain in the preliminary phases and more traditional vaccines won't be available for months.

    In the meantime, it will be up to us to keep washing our hands, avoiding crowded places, and doing what we can to control COVID-19. More info about the virus and what we can do to protect ourselves can be found here:

    The family radiation cookers. This one is a Beaumark purchased in 1985 and uses microwave radiation. The traditional one in the reflection uses infrared radiation.

    Recently, at a meeting in another city, the conversation turned to the example of a new home owner who refused to have a standard appliance installed for fear that it would expose the family to a greater risk of cancer.

    Seriously? This one is still out there?

    More than 50 years ago, in 1967, Amana Corporation introduced the Radarange, and with it, a whole new way of cooking food. Within a few decades, Amana and other companies had made the microwave oven standard equipment in nearly every kitchen in the developed world.

    At the same time, there was unease about the new technology, in no small part because of a single word used to describe it: radiation. 

    ​My mother remembers newspaper advice columns at the time fielding questions from concerned homemakers about the new devices. They were reassured of their safety, but the unease persists to this day. 

    What would have happened, I wonder, if instead of “microwave radiation,” they had called it “microwave light?” Both are equally accurate.

    Microwave light has wavelengths shorter than radio but longer than infrared. The heat you feel of one of those overhead heaters in a garage is infrared light. Another way to think of wavelengths is colour: the wavelengths of red light are longer than violet, for example.

    Microwaves are pretty useful. Some wavelengths resonate with water molecules. That means if you shine microwave light on a water-containing substance, the water molecules start to move faster, or get hot. This is how a microwave oven works. 

    Microwaves are also used extensively in telecommunications - your cell phone uses them, for instance (typically between 900 Mhz and 1,800 Mhz). Microwaves are used because they can carry much higher information density than radio waves. So, when you’re using your cell phone, you’re using a microwave transceiver RIGHT BESIDE YOUR BRAIN (insert terrified scream here, and yes, I’m being sarcastic). 

    Popular phrases such as “nuke some dinner” don’t help. People are afraid of radiation, or at least what they think it radiation is. Light does radiate, even if you can’t see it (as I mentioned with the infrared heater). Incidentally, any incandescent bulb actually gives off much more infrared than visible light, which is why you can use them as a heat source. 

    Also, unless you’ve been very careful or very lucky, we pigment-challenged types have almost certainly had one or more radiation burns in our lives. This is because the shorter the wavelength of the light, the more energy it carries.

    Light starts to get dangerous to us once you get into the ultraviolet range, something our sun is quite good at producing. So public health folks urge us to be careful, wear clothing, put on sunscreen to protect from radiation burns that can increase our risk of skin cancer. But we don’t often think of these as radiation burns; we just lament that we were careless and got a sunburn.

    Words carry both meaning and emotion. “Light” and “radiation” can often be used interchangeably, but they carry much different emotional baggage. “Natural” and “synthetic” can be used to describe the same product, but how do these words make you feel? How about “organic” or “industrial?” “Corporate” vs “co-op?” 

    So, when crafting and consuming messages for ourselves and our clients, let us choose our words carefully – not only for meaning but for emotion.

    In both the telling and the hearing, stories begin with people.

    My passion is taking complex science transforming it into stories that engage and excite. As a strategist, I ask questions. Who are we talking to? Where are they and where do they get their information? What do they believe?

    Over more than 30 years, my work appeared in weekly and national publications, broadcast and online media. For more than a decade at the University of Saskatchewan, I worked to identify and shine a light on the innovative minds and discoveries at one of Canada’s top research universities.

    We live in challenging times, where innovation and knowledge are often met with rejection and disbelief. This has consequences for issues critical to our species and our environment, from vaccines and genetic engineering to energy and climate change. I believe science writers and communicators have a vital role to play.

    Part 1: How the Manitoba government’s return to a deregulated hog industry could actually contribute to a world health emergency.

    The Pallister government has just passed its “Red Tape Reduction and Government Efficiency Act.” The bill makes it easier (and cheaper) for pig producers to build new factory barns, expand existing ones, store and dispose of the waste and to even spend less on fire protection. 

    According to the industry group, “Manitoba Pork,” as many as 100 new factory barns may now be built over the next ten years. 

    What the Bill will not do is stop the dangerous overuse of antibiotics in animal agriculture. Livestock owners around the world (including Manitoba’s hog producers) have long been giving these medicines to their animals, whether to treat the sick, prevent the healthy from getting sick, or simply to fatten them up for market.

    This is all perfectly legal here and in many other countries.

    While it's true that antibiotics are sometimes used and abused in human medications too, the Public Health Agency of Canada (PHAC) estimates “80% of all antibiotic use in Canada occurs in the raising of animals for food.” 

    And, about three out of every four doses given this way, are identical to the drugs you and I need to fend off deadly infections.

    The PHAC goes on, “There is increasing evidence that the use of antimicrobial agents in livestock production is an important contributing factor to the emergence of antimicrobial resistance (AMR) in humans.” AMRs are sometimes called “superbugs” which, because of this inappropriate use, have developed a resistance to treatment by most or all of the medicines available today. 

    So scenarios where doctors have to advise their patients that “There’s nothing more I can do for you," are becoming alarmingly more frequent. 

    Three days before the Manitoba bill was approved, the World Health Organization sounded its most urgent alarm yet over the administering of antibiotics to food animals. The WHO says things must change, if we are to preserve the effectiveness of these life-saving medications.The UN agency advised farmers and the food industry everywhere, to simply stop giving animals such medications altogether, whether to promote growth or prevent disease. Healthy animals should only be treated if disease is diagnosed elsewhere in the same herd. And, even while treating animals already sick, only medications not considered critical for the treatment of human infections, should be used. 


    Image credit - OECD

    But data from the Organization for Economic Cooperation and Development are even more alarming. Representing 35 developed countries, it notes that AMR is “highly prevalent” in its member countries (including Canada). It estimates the yearly loss of life, worldwide, probably runs into the tens of thousands, already. But current rates of resistance are increasing to the point where ten million people a year could be dying in this way by 2050! This, the OECD notes, would "move the needle" on the human cost of AMRs, from “substantial” to “enormous.” While the bulk of the deaths would be in Africa and Asia (see OECD table), there could still be 700 thousand in North America by that time. (No breakdown is given for Canada.)

    Why, you ask, would an economic organization get involved in a health issue? Because, it expects future increases in health costs to also be enormous; almost $3 trillion by 2050, for OECD countries alone! That's because AMR patients are sick longer, need more (and costly) treatments, more tests and are three times more likely to die.

    With new barns and more hogs now on Manitoba’s horizon, only pro-industry spin-doctors would dare to argue that this won’t mean more antibiotics, as well. (The OECD expects such usage to increase by a staggering two thirds by 2030.) 

    I have e-mailed both Premier Pallister and “Manitoba Pork” to ask them about these concerns. Neither has responded, so far.

    So, if the world pays as little heed to this prevailing medical wisdom as the Pallister government and the industry seem to be doing, for this Manitoban, "optimistic" just got harder to be.

    Peach flower, fruit, seed and leaves as illustrated by Otto Wilhelm Thomé (1885) public domain via Wikimedia Commons.

    Peaches and nectarines are the same fruit minus a small genetic variation that makes nectarines hairless. When I first learned this little trivia tidbit I wondered about the difference in flavour. I prefer nectarines to peaches, but wondered if the taste difference was all in my head. Well, it’s not.

    The genetic variation affects flavour, aroma, size, shape and texture. While the rough location of the genetic change has been known for some time, the exact gene and the exact change in the DNA sequence of “nectarineness” has been a mystery. In March, scientists from Italy finally identified a disruption in a “fuzz” gene that is absent in peaches.

    Agriculturists in China gifted fruit lovers with the peach about 4000 to 5000 years ago. At least 2000 years ago, again in China, nectarines burst on to the scene. Charles Darwin pondered about how nectarines popped up on peach trees and vice versa and described the odd finding of one fruit that was half and half. Would we call that a “peacharine?”

    Darwin, and others, deduced that the nectarine was a peach variety. In 1933, scientists determined a recessive gene variant was responsible for the inheritance pattern of the nectarine's hairless (glabrous) skin. The glabrous trait was given the designation G, with big G for the normal fuzzy peach character and little g for the glabrous nectarine character. Each fruit has two copies of this gene. Each parent gives one to the offspring fruit, which can be either GG, Gg, or gg, and only the gg fruits are nectarines.

    The chromosomal location of the G trait was already roughly landmarked but the Italian research team zoomed in on the spot, sort of like how you zoom in to street view with Google maps. Many DNA sequence differences exist between nectarines and peaches that are not located in genes but are useful as landmarks along the chromosomes. These are called genetic markers. To zoom in on the G trait, the researchers crossed peach and nectarine trees and followed the offspring through two generations. The offspring had a mixture of peach and nectarine markers along their chromosomes but certain genetic markers, the ones closest to the G trait location, always went along with the nectarineness. These genetic markers landmarked the region to search for genes with mutations that could explain a nectarine’s fuzz-less-ness.

    Within the landmarked region, the researchers identified a disrupted gene. The peach to nectarine gene disruption is a genetic modification by the hand of Mother Nature, an insertion of a transposable element. This type of DNA element can move because it contains its own code for the production of an enzyme that can “cut”and “paste” the transposable element to other locations in the genome. Transposable elements can get pasted right in the middle of genes, disrupting the DNA sequence. They are a known cause of genetic variation in plants. If you like chardonnay wine, you can thank a transposable element for disrupting the cabernet grape genome long ago.

    In nectarines the transposable element stuck itself right in the middle of a gene called PpeMYB25. Genes with similarities to PpeMYB25 in other plants are important for making plant hair, called trichome, which can occur on the stem, leaves, flowers and fruit of plants. The PpeMYB25 gene is the recipe for making a protein that is a transcription factor, a type of protein that controls when and how much other genes are turned on, so a mutation in this one gene could explain not just baldness in nectarines but other nectarine characteristics as well, depending on what these other genes are that it controls. In this report the researchers focused on the peach fuzz characteristic. When they looked at flower buds during the period when fuzz or trichome first develops, they found PpeMYB25 to be active in the peach but not the nectarine buds.

    This is the first description of a specific genetic modification that can explain the difference between peaches and nectarines, something that has long been a mystery.

    This research makes a strong case that nectarine lack of fuzz is due to the inability of nectarines to produce the PpeMYB25 protein. How lack of PpeMYB25might lead to the other nectarine characteristics — flavour, for instance — still needs to be worked out.

    I recently had the privilege of participating in an improvisation course called: Act Your Science.  The aim of the course was to provide the foundational skills for improvisation, which in turn would improve our public speaking and science communication skills. However, it turned out to be so much more!

    Dennis Cahill, the Artictic Director at Loose Moose Theatre, directed each 2 hr. session, which ran for five weeks. Dennis’s directorship was always filled with compassion, clarity and patience.  He shared his extensive improvisation knowledge and experience in such a fun manner we were excited to engage in a learning process that always resulted in full-fledged laugher!

    The following core principles of improv were taught and repeated in each session. As you will see, the fundamental principles of improv can be applied to any relational interaction that one engages in, not just when performing on stage.

    Be Present

    The importance of being present in the moment was a central theme throughout this course.  It is critical that improv participants enter into interactions with pristine active listening, as nothing is rehearsed before the interaction occurs. The interactions that had the greatest impact and resulted in the most laughter occurred during the most authentic moments of exchange.

    “Don’t think. Get Out of Your Head. Stop Planning and Just Go”

    -Amy Poehler-

    Take Chances

    Dennis encouraged participants to say ‘YES’ when called to participate on ‘stage’.  By the end of the five sessions, it seemed that everyone was jumping up to participate! I have to admit that I had to restrain myself to saying YES to allow others the opportunity to say YES!  Dennis made sure to repeat that when we take chances, our learning is expanded.

    “Just say Yes and You’ll Figure it Out Afterwards.”

    -Tina Fey-

    Make Mistakes

    Dennis was commonly heard saying “mistakes are good” and “don’t be afraid to make them!”  We were always encouraged to be okay with making a mistake and to respond in a light-hearted manner when they occur with laughter and ease.  Dennis wanted us to always remember that the audience is on our side and want nothing more than for us to succeed!

    “If You Stumble Make It Part of the Dance”

    The goal of this course was more than achieved! I feel confident in suggesting that all of the participants will be more present, take chances more often and be okay with making mistakes in future speaking opportunities. For myself, this introduction to improv has transformed into ensuring that I make it a life long hobby that I will regularly participate in.  It the meantime, until we connect again, I will end by saying:

    “It is Always Sad When a Good Show Comes to an End!”

    By: Jennifer Bon Bernard

    Jennifer Bon Bernard is a graduate student at University of Calgary in the department of Community Health Sciences. She always enjoys having fun    and exploring her artistic soul whenever the opportunity arises. Improv has brought so much laughter and happiness to her life that she will continue to make this apart of her creative journey forever! Jennifer highly recommends that if you ever the opportunity to enroll in an improv class that you say “YES!”

    Act Your Science is the result of a collaboration between the University of Calgary, the Canadian Science Writers Association and Loose Moose Theatre.  Act Your Science is scheduled to take place again at the University of Calgary in early summer 2017. Fifteen spaces are available for the five two hour sessions. CSWA members as well as University of Calgary science graduate students are invited to participate at no cost. Yes there will be additional field trips to Loose Moose Theater and a few pub nights because the fun just doesn't want to stop once you learn to listen, take chances and laugh together without the fear of making a mistake.

    New research suggests that pollution may be playing a bigger and more ominous role in pushing many of Canada's plants and animals to the brink than earlier thought.

    One of the species at risk, the small white lady's slipper, Cypripedium candidum. Photo by Mason Brock.

    Habitat loss, climate change and invasive species are often referred to as significant players in Earth's calamitous descent into a sixth Great Extinction. While those factors obviously play a part, this new study better recognizes the magnitude of the role played by yet another culprit in the piece - pollution. The authors of the research label contamination of our air, soil and water as a "pervasive, often invisible threat to biodiversity in Canada." And, up until now, the threat it poses, especially to vascular plants (ones that flower, bear fruit and seed), they suggest, has been underestimated by experts in the field. These include ones who serve on Ottawa's advisory agency, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). And, because so little is known about the subject, they've "frequently identified the threat of pollution as absent or negligible," even for species living within areas affected by it.

    In order to design a better way of analyzing these threats, the seven-member team mapped known pollution sources and compared them with known ranges of 488 endangered species in this country. These included mammals, birds, plants, freshwater fish, reptiles, amphibians, arthropods (such as insects and crabs) and molluscs (like slugs and snails). It found that, on average, 57% of the habitat of each species also contained at least one pollution source.

    "Our analysis shows that species at risk and pollution sources co-occur at a high rate in Canada. In general, the highest densities (of pollution sources and species-at-risk) are concentrated in the south, where the human population density is also highest. The richness of these creatures overlapped strongly with areas of greatest urbanization and landscape modification, such as Ontario, the Prairies and the Lower Mainland of BC."

    Pollution. A challenge of both national and global magnitude

    Quoting Government of Canada numbers, the study states: "Tens of thousands of chemicals exist in commerce today and the size of the global chemical industry is set to double by 2030. Contaminants such as flame retardants undergo transformations into more toxic breakdown products in the environment that contribute to heightened environmental effects.

    "Each year in Canada, some five million tonnes of pollutants are released from seven thousand facilities. These have included about 700 pipeline spills over the past decade in which natural gas, crude oil and other contaminants have escaped into our environment."

    "Each year in Canada, some five million tonnes of pollutants are released from seven thousand facilities. These have included about 700 pipeline spills over the past decade in which natural gas, crude oil and other contaminants have escaped into our environment."

    Such spills are capable of either killing species immediately, or dealing "sub-lethal" blows which might sap their fitness, reduce their ability to reproduce or even deprive them of their food.

    "Runoff from urban, agricultural and industrial landscapes contaminates Canada's groundwater and downstream aquatic ecosystems. Finally, over 23 thousand known or suspected contaminated sites have been identified and classified in urban, rural and remote areas of Canada, many of which are contaminated with petroleum hydrocarbons, metals and/or persistent organic pollutants such as PCBs."

    Jenny McCune - Ast. Prof. Dept. of Biological Sciences, University of Lethbridge, AB

    The lead author of the study, Prof. Jenny McCune (l.) told PinP in an e-mail, "We did not measure the effect of different pollutants on individual species. We need more research to test the effects of specific contaminants on individual species at risk. We simply measured the potential for species to come into contact with different types of pollution based on the geographical overlap between sources of pollution and the known ranges of species at risk.

    "The eastern prairies (MB and eastern SK) have sources of all 6 categories of pollution ( as defined by the International Union for the Conservation of Nature): household sewage and urban waste water, industrial and agricultural effluents, garbage and solid waste, air-borne pollutants, and excess energy"

    The authors of the study, recently published in the journal, Facets, hope this new information will help us better understand just how much endangered wildlife are threatened, and where to go from here.

    Other research only confirms the worst fears.

    The Bakken formation (above) is a major oil deposit straddling two provinces and two states. US Geological Survey.

    A study published last year in "Cogent Science," reminds us that the Bakken oilfield "overlaps with one of the largest areas for grassland birds in North America. Access to the oil is made possible by fracking and horizontal drilling, both controversial techniques which have been banned in other parts of the world. This paper illustrates that oil development is impacting species through habitat destruction, oil and noise pollution, invasive species and road infrastructure. Current wildlife policy in Saskatchewan is insufficient to protect species at risk in the Bakken formation."

    Grassland birds are said to be the among the group most vulnerable to environmental pressures in all of North America.

I’m authorized to receive embargoed material through the Science Media Centre of Canada, the Royal Society and the World Health Organization. This allows me to “get a jump” on important stories by fleshing them out with fact-checks and interviews, in advance. Often, this arms me with a “hot-off-the-press” story that’s ready to go, the moment the embargo is lifted.

    I’m prepared to supply interested publications with important stories in the field of the Earth Sciences – stories often stranger than fiction! I publish (PinP), “Where science gets respect.”

    The year is 2300. You live somewhere in the middle of North America, far from the flooded coastlines. The air is dry, the streets dense with people. You enter a restaurant, and a TV broadcasts the most recent news: New York City has collapsed into the Atlantic Ocean.

    This is the future I often imagine when I think about climate change. It’s part of a narrative that has invaded my subconscious; that the future is bleak, and it’s inevitable.

    This is the unfortunate bi-product of the moment we’re living in.

    If we consider the media as a place that both reflects and shapes our culture, the stories it tells can have a powerful impact on the collective consciousness. Everything we put into it is also pumped out in ways that are impossible to predict.

    Lately the trend has been towards stories that reinforce the narrative of the coming apocalypse--“Climate Change: do more now or risk catastrophe,” reads one headline from The Guardian.

    But as we continue to think about climate change, and about how we talk about climate change, we have some serious questions to consider. What does it mean for news to cover climate disasters while also holding out hope for a brighter future? How do we ground our stories about climate in a world that is already overloaded with information? How do we engage audiences without losing them in the sheer size of it all?

    Maybe we’re not ready to address these questions yet; society needs to enter the realm of action before the conversation can go in any other direction.

    But we might get there sooner than we think.

    Assuming our institutions respond to the alarm, our conversations could change rather quickly. In as little as 30 years, we could be in a space where we celebrate our climate victories. We could revere green CEOs as much as we do current tech giants; we might compete with our neighbours over who has the biggest solar panel; and we could look back with regret at the time where we barely avoided catastrophe.

    This is a version of the future that is not impossible; the world has changed a lot in the past 30 years. The same can happen in the next 30.

    It may seem unlikely now. But in the face of catastrophe, we can only hope.

    As global temperatures rise, we are experiencing increased risks of disease, extreme weather events, and growing uncertainty about the future of our planet. Climate change affects everything from the air we breathe to the water we drink. A warming planet may also mean a change in our diets, according to a new study conducted at the University of Toronto, which found that warmer waters may reduce the quantity of Omega-3s available worldwide.

    Omega-3s are fatty acids that play an essential role in our bodies and provide us with numerous health benefits. There are three types of Omega-3s, including ALA, EPA, and DHA. The body uses ALA to create energy. EPA helps reduce inflammation, and DHA is an essential component in our eyes and brains.

    Consuming adequate quantities of DHA improves eye health, reducing the chances of macular degeneration. It also decreases the likelihood of depression and plays an essential role in brain functioning and development, especially in unborn babies.

    The majority of DHA in our diets comes from consuming fish. However, fish acquire DHA from eating algae. This is a problem because as global temperatures rise and the water warms up, algae will produce less DHA, according to a new study conducted at the University of Toronto.

    Algae is very sensitive to changes in the water. When water temperatures rise, the cell membranes in algae become too fluid. Therefore, algae stop producing Omega- 3s in warmer water to maintain adequate membrane fluidity, according to the study. 

    Algae is low on the food chain, which means the less DHA produced by algae, the less DHA consumed by fish and in turn, people.

    The present study used computer modeling to estimate DHA levels in different climate change scenarios developed by the United Nations. Results showed if greenhouse gas emissions continue at current rates over the next 80 years, the amount of available DHA will decrease by 10 percent. This reduction in DHA means that around 96 percent of the population will not have enough Omega-3s in their diet.

    Even if we slow the rate of greenhouse gas emissions, the study predicted that the amount of available Omega-3s will still drop significantly.

    “Based on the current trajectory of the climate, even the most optimistic projections have us heading towards a pretty alarming loss in human potential,” Tim Rodgers, a co-author of the current study, said in an interview with the University of Toronto. 

    A lack of DHA is of particular concern for developing babies since this Omega-3 is crucial for brain development. Consuming enough Omega-3 during pregnancy is associated with higher intelligence and lower risk of behavioral and developmental problems in the child.

    Evidently, climate change is having a significant impact on all aspects of life. This study highlights the importance of reducing greenhouse gas emissions, demonstrating the detrimental impact climate change may have on future generations.

    In terms of threatening issues affecting our way of life, climate change stands as one of the biggest threats of the modern age. In the last few months, climate change has been attributed to a number of major incidents. These include a series of floods causing widespread devastation across Canada, the Arctic Circle being devastated by its worst wildfire season to date, as well as Greenland losing over 200 billion tons of ice in the span of a month.

    In the recent federal election, nearly 30 per cent of Canadians saw climate change as one of the top three most important issues in determining a vote. In terms of the most important reasons to act on climate change, one of the most important reasons that spur adults to actis to ensure a better future for their children.

    As it stands youth from all over the globe, have started taking the lead in the fight against climate change. Most recently, young people across the globe took to the streets in protest, demanding that bolder actions be taken to address the issue of climate change. In Canada, it is estimated that over 1 million people across eight major cities, as well as in small towns participated in this climate strike. The city of Montreal had the biggest number of protesters in the country, with the number of protesters reaching over 500,000 people.

    The initiatives taken by young people acting against climate change does not stop there. Earlier this week, multiple Canadians youths filed lawsuits against the federal government for failing to take action against climate change and putting their own wellbeing and security at risk.

    This represents one of many instances where groups of youths have attempted to file lawsuits their governments for failing to act to prevent climate change, putting their lives, their liberty, as well as their security at risk.

    We stand at a critical turning point in history. Thanks to social media, youth possess a powerful tool that allows their voices to be heard. With climate change growing worse each year, it is vital that we listen to the concerned voices of our youth and take immediate action to ensure that we can still provide them with a future worth living. This is the only world we have, and it should be one where our children and their descendants can thrive and grow without fear of worrying about the looming threat of climate change.
