Good news about the environment is hard to come by. For one thing, in the view of many people, Canada’s image has been tarnished, or should we say tarred, by the ongoing development of the oil sands. For another, the economic rise of China and India appears to be at the cost of the environment. Global warming threatens the world’s food supply, and is being linked by studies to some (though not all) of the extreme weather events the world has seen recently.
But when environmental change is looked at through the lens of time-the modern environmental movement arose in the early 1970s, a short 40 years ago-there is reason for hope. Collective action, progressive policies and new technologies have actually limited damage and saved lives. So, with another Earth Day on the horizon (it’s on April 22), here are seven green victories-big and small, from near and afar-that are cause for celebration.
