Scientists have been widely acknowledging climate change as a real and pressing danger to our planet for a while now, but it seems pretty clear that none of us are actually going to do anything about it as long as we’ve got all-day breakfast at McDonald’s and another decade of Marvel movies to look forward to. Thankfully, we’ve got celebrities like Leonardo DiCaprio to watch out for us. Not only is he producing a Captain Planet movie, but he and Fisher Stevens also made a climate change documentary called Before The Flood that was screened at President Obama’s South By South Lawn festival earlier this year.
