Scientists have calculated the total amount of plastic ever made: 8.3 billion tons. Looked at another way, that's as heavy as 25,000 Empire State Buildings or one billion elephants. And incredibly, almost all of it has been made in the last 65 years.
So what's the problem? Much plastic is in the form of packaging which is used just once and then thrown away. According to a major new study from the University of California, 9% of this is recycled, 12% is completely burnt and 79% goes to landfill. And because most plastic is not easily disposed of, once it's in the ground, it stays there.
It's a situation that has led the paper's lead author, ecologist Dr. Roland Geyer, to say that we are "rapidly heading towards ‘Planet Plastic'". The team behind this report also estimate that eight million tons of plastic waste are escaping into the sea every year. This has caused concern that plastic is entering the food chain, through fish and other sea life which swallow the smaller fragments.
Of course, the reason why there's so much plastic around is that it's an amazingly useful material. It's durable and adaptable, and is used for everything from yoghurt pots to spaceships. But it's exactly this quality which makes it a problem. The only way to destroy plastic is to heat or burn it -although this has the side effect of harmful emissions.
So what's the alternative, other than using less plastic? Oceanographer Dr. Erik van Sebille from Utrecht University says we're facing a "tsunami" of plastic waste, and that the global waste industry needs to "get its act together".
Professor Richard Thompson, a marine biologist from Plymouth University, says it's poor design that's at fault. He says that if products are currently designed "with recyclability in mind", they could be recycled around 20 times over.
