Our team of photo editors combed through the amazing imagery from all over the globe this year to come up with their favorites.
Many of their choices serve as a reminder of the work that still lies ahead of us — the perils of our fossil fuel-based economy and the threats to people, wildlife, and the planet posed by corporate greed. But many more of them capture the moments that will define the environmental movement in 2015 — our soaring victories, remarkable acts of courage, and displays of people power.
These are the images that shocked us, inspired us, and drove us to take action. See them all below, and find more moments caught on film at our Flickr account.
