Coral reefs are among the ocean's most wondrous achievements. Like a massive mega-city made up of microorganisms, these diverse ecosystems provide shelter for many different marine species and they're also a real treat to look at. Sadly, manmade climate change hasn't been particularly kind to corals, and a new report suggests that not only are the ocean's coral reefs stressed out, but they're starting to buckle under the pressure.
The study focused on a process called "bleaching" that occurs when the algae that sustains the coral is pushed away due to increased heat. If the algae isn't there to deliver nutrients to the coral, it loses much of its color and, if the algae doesn't return for an extended period of time, the organisms that live in the coral will die.
