Earth is becoming 'Planet Plastic'

来源:BBC 作者: 时间:2017-07-20 Tag: 点击:

 

US scientists have calculated the total amount of plastic ever made and put the number at 8.3 billion tonnes.

It is an astonishing mass of material that has essentially been created only in the last 65 years or so.

The 8.3 billion tonnes is as heavy as 25,000 Empire State Buildings in New York, or a billion elephants.

The great issue is that plastic items, like packaging, tend to be used for very short periods before being discarded.

More than 70% of the total production is now in waste streams, sent largely to landfill - although too much of it just litters the wider environment, including the oceans.

"We are rapidly heading towards 'Planet Plastic', and if we don't want to live on that kind of world then we may have to rethink how we use some materials, in particular plastic," Dr Roland Geyer told BBC News.
