There are a number of significant dates on environmental and climate justice issues. ETFO encourages schools and communities to recognized these dates.  

Every year on April 22, Earth Day marks the anniversary of the birth of the modern environmental movement in 1970. 

Today, Earth Day is widely recognized as the largest secular observance in the world, marked by more than a billion people every year as a day of action to change human behavior and create global, national and local policy changes. 

Now, the fight for a clean environment continues with increasing urgency, as the ravages of climate change become more and more apparent every day.  Read more at

According to the World Wildlife Fund (WWF), "Since 2010, over a million Canadians have participated in National Sweater Day at their schools, workplaces and homes by turning down their thermostats and wearing their favourite sweaters to stay warm. National Sweater Day is an opportunity to raise awareness about climate change and energy conservation, and show how together - classroom-by-classroom, school-by-school - we can be a part of the solution."

According to the UN World Water day website, "...As the global population grows, so does the demand for water, which depletes natural resources and damages the environment in many places. Fighting climate change will open up vast opportunities for the economy in many areas. We need to embrace circular production systems and use water much more efficiently. Climate change can feel scary and daunting. But there is one simple step you can take immediately that will make a big difference: don't waste water."

On March 28, Canadians are asked to turn out the lights for an hour starting at 8:30 p.m. to draw attention to climate change. 

In Canada, populations of more than one-half of monitored species have already declined by 83 per cent on average since 1970. To reverse nature loss by 2030, every hour is important.

In designating a World Bee Day, the UN is seeking “to raise awareness of the importance of pollinators, the threats they face and their contribution to sustainable development.”  

“The greatest contribution of bees and other pollinators is the pollination of nearly three quarters of the plants that produce 90% of the world’s food. A third of the world’s food production depends on bees, i.e. every third spoonful of food depends on pollination.”
