So many that over one million plastic bottles are being used every minute and they're damaging our environment. While it's difficult to know exactly how many marine animals are killed by plastic pollution, it's been estimated that plastic pollution kills 100,000 marine mammals every year. 81 out of 123 marine mammal species are known to have eaten or been entangled in plastic, and all seven sea turtle species are affected.
