As people around the world celebrate Earth Day, learn how you can make more sustainable choices with research backed by Waterloo experts
Inspired by the theme “Our power, our planet,” Earth Day 2026 reflects a fundamental truth: environmental progress is sustained by the daily actions of communities, educators, workers and families protecting where they live and work.
As we celebrate the planet and stewardship today, we share four environmental research-driven actions you can take to create transformative change for people and the planet.
Almost two-thirds of electronic devices that Canadians scrap still work, according to new research by Dr. Komal Habib. The study found that products like phones, laptops, tablets, desktop computers, televisions, refrigerators, microwaves and laundry appliances were replaced even though they were still working. E-waste from these disposed products are estimated to grow to a total of 2.3 million metric tonnes, or enough to fill 18 CN Towers, by 2030. Therefore, keeping your devices and looking to repair them are excellent ways to save money and the environment.
Extreme weather events and heat waves already occur across Canada and will continue to become more intense. The good news is there are actions you can follow to help limit risk. The Intact Centre on Climate Adaptation has developed a list of top actions Canadians can take around their home and property to reduce their risk. There are even nature-based measures, such as planting a rain garden to absorb water and avoid basement flooding or using shade trees to limit direct sunlight from heating a home (allowing for cost savings on air conditioning).
Roads are a significant threat to biodiversity, often resulting in declines in sensitive species like turtles. With the onset of spring, animals are on the move. Paying careful attention to animal crossing signs and watching the roads are important first steps, according to Dr. Chantel Markle. In the event you see a turtle crossing and you can stop safely, help it across the road and do your part in reducing reptile road mortality. Alternatively, if you find an injured turtle, contact the Ontario Turtle Conservation Centre.
The food choices we make every day can have significant impacts on the environment, from greenhouse gas emissions and deforestation to freshwater pollution and organic waste. Being mindful about how our food is made and where it comes from is a critical step in acting for a positive climate future. To eat more sustainably, source local, seasonal products, choose sustainably certified options, minimize your food and plastic waste, and try to eat more plant-based options where possible. The effort can start right on campus as 40 per cent of food purchased by Food Services is sourced locally or sustainably.
