Plastic. It seems like just about everything we use is made of some type of plastic. 230 million tons of plastic are consumed worldwide every year. Unfortunately, more than 90% of plastics are not recycled. And since plastic does not biodegrade, the waste sticks around for hundreds, even thousands, of years. This has resulted in a major ecological problem in the world’s oceans. Pollution, along with other human action like overfishing, has put the world’s oceans in serious trouble.
