2050年海洋中的塑料垃圾将超过鱼类
[font=Verdana, Arial, Tahoma][size=14px][b]There will be more plastic than fish in terms of weight in the world's oceans by 2050, the World Economic Forum warned Tuesday.[/b][/size][/font][font=Verdana, Arial, Tahoma][size=14px][b]1月19日，世界经济论坛发出警告：到2050年，世界各大海洋中的塑料垃圾总重量将超过海中鱼类。[/b][/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]Plastic has become one of the world's most popular materials, combining amazing functionality and very low production costs. Its use has increased 20-fold in the past 50 years and is expected to double again in the next 20 years.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]Almost everybody in the [url=http://www.enread.com/news/life/103310.html]world[/url] comes into contact with it -- over a quarter of all plastic is used for packaging, the most popular use of the material.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]But only 14% of plastic packaging is collected for recycling. The reuse rate is terrible compared to other materials -- 58% of paper and up to 90% of iron and steel gets recycled.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]It gets worse. Almost a third of all plastic packaging escapes collection systems and ends up in nature or clogging up infrastructure.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]"After a short first-use cycle, 95% of plastic packaging material value, or $80 billion to $120 billion annually, is lost to the [url=http://www.enread.com/news/life/103310.html]economy[/url]," the WEF said in a report.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]The report is based on interviews with over 180 experts and on analysis of over 200 reports.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]They estimate that by 2050, the amount of plastics produced globally will increase three times to 1,124 million tons. By then, the "plastic economy" will take up 15% of the world's global carbon budget, compared to just 1% today.[/size][/font]
