The first Earth Day was held on April 22, 1970 and the conversation about protecting the environment has changed dramatically over the past 54 years.

Back then, the “environmental movement” was a fringe cause. Today, the fight against climate change is an international priority.

The Conversation‘s global network has published thousands of stories exploring how the climate crisis is affecting all aspects of our lives.

At The Conversation Canada over the past week, we’ve published stories about how the Canadian federal budget misses the mark on water investments; roadblocks to a "just transition" for oil and gas workers; the future of renewable energy in Alberta; and how climate education can help young people form environmentally friendly habits.

Today, Amar Laila and Jess Haines from the University of Guelph and Cristina Gago from Boston University offer four strategies to reduce household food waste.

“The average household is throwing away almost $900 each year and with nearly seven million Canadian households struggling to get enough food on the table — and two in five reporting cost as a barrier to healthy eating — that waste adds up,” they write.
