An often forgotten dimension of sustainability is that of health. A recent survey on sustainability at uOttawa revealed that when students think about sustainability, they usually think about how it relates to the environment and forget about the the social elements, which include health. Certainly the health aspects of sustainability have been popping up in the news a lot lately, even if we don't immediately link it to the environment. Poor air quality and environmental contaminants related to floods, fires, and climate change come to mind fairly quickly, but there is a silent killer in the room and it is stress related to the environment. The recent phenomenon of climate anxiety is washing over youth like a tidal wave. A 2017 report by the American Psychological Association  suggests that worrying about climate change is having a serious impact on our mental health. And as you can imagine, the more we hear about bad things happening in our environment, the more people worr...

As a long time fan of brushing my teeth, I was hesitant to adopt this popular zero waste lifestyle change. I love making things and I love trying new things, but most natural toothpaste recipes I researched called for simple yet not super appetizing ingredients. Baking soda? Bentonite clay? The skepticism was high even though most recipes called for a sweetening or flavour agent like essential oil or stevia. But then I looked closer at the ingredients in typical tooth paste and did a 'lil internet research. This is what I found: Triclosan : So this chemical is actually classified as a bioaccumulative, non-biodegradable pesticide! It is bad for the environment and our waster systems as it is very toxic to aquatic organisms. But it also isn't great for you, as it is linked to hormone interference and contributes to antibiotic resistant bacteria. Propylene Glycol : This chemical is often contaminated with known carcinogenic ethylene oxide and 1,4 dioxane during the manu...

Genetically modified organisms (GMOs) and our food systems are hot topics nowadays and there is a lot of information floating around out there. This past November, St Paul’s University played host for Ottawa’s GMO symposium. As part of this event, our friends at the Interdisciplinary Food Lab (LEILA) hosted a special guest lecture about GMOs and related regulations in Canada. What is a GMO? To understand GMOs we need to look at DNA. Think of DNA as the blueprint for everything in our body. DNA holds the code for arranging amino acids, which create proteins, which we use for different reactions or to form different tissues and membranes. Although this is still a relatively new science, it has come a long way in part because of the Human Genome Project (in which the whole human genome was mapped and the genes responsible for coding specific proteins were identified). When an organism is genetically modified we cut and paste DNA from another organism into the original organism’s...
