Plastic Planet

More than five trillion pieces of plastic, collectively weighing nearly 269,000 tonnes, are floating in the world’s oceans, causing damage throughout the food chain, new research has found.

Data collected by scientists from the US, France, Chile, Australia and New Zealand suggests a minimum of 5.25tn plastic particles in the oceans, most of them “micro plastics” measuring less than 5mm.


The volume of plastic pieces, largely deriving from products such as food and drink packaging and clothing, was calculated from data taken from 24 expeditions over a six-year period to 2013. The research, published in the journal PLOS One, is the first study to look at plastics of all sizes in the world’s oceans.


While spread out around the globe, much of this rubbish accumulates in five large ocean gyres, which are circular currents that churn up plastics in a set area. Each of the major oceans have plastic-filled gyres, including the well-known ‘great Pacific garbage patch’ that covers an area roughly equivalent to Texas.


“It’s hard to visualise the sheer amount, but the weight of it is more than the entire biomass of humans. It’s quite an alarming problem that’s likely to get worse.”

Even if we somehow tame climate disruption, plastic will destroy this planet.


Here's another theory why SETI cannot find intelligent life in the universe. About the time civilizations develop the ability to communicate, they choke to death on their own waste.
