In an effort to slow down the effects of global warming, scientists from Germany, Italy, India and Chile are planning to dump 20 tonnes of non-toxic iron sulfate into the sea. The iron particles — which will be spread around a 1,000 square kilometer area — should theoretically create conditions for large amounts of phytoplankton, algae and microorganisms to grow and, ideally, help soak up the carbon dioxide that’s slowly causing our planet to roast.
