you should care about corals

Rising acidity levels due to climate change are killing the corals and other see animals that need certain acidity levels to grow shells and live. No biggie, you think? Well, coral reefs are critical ocean ecosystems, very fertile areas that provide major sources of food for fish. Including fish that us humans eat. So it isn't just a question of pretty reefs disappearing.

The climate is kind of like an operating system for the Earth, an OS that has been stable and conducive to agriculture and the rise of human civilization for the past several thousand years. By allowing business-as-usual unchecked carbon emissions we are locking in a series of changes that could dramatically alter how our planet's operating system works. And we can't be sure the OS won't crash. We need to do something quickly to at least try to mitigate the worst effects of climate change, while we (maybe) have a chance.
