Everyone's dream boyfriend Leonardo DiCaprio was at the Climate March yesterday because he is passionately committed to the environment, as we all know.
And because he cares so much about the environment, he also recycled a file folder to use for his sign. So thoughtful! And doesn't he look dapper in his little newsboy cap!
He's not on board with Trump's rollback of restrictions on mining, oil drilling and greenhouse gas emissions at coal-fired power plants.
Leo was keen to demonstrate that climate change isn't a hoax; the overwhelming consensus of scientists confirm that the world is warming and that man-made carbon emissions are primarily to blame.
(Also, he doesn't eat animals because he loves them. What a man!)
