Second earth will soon be needed, warns WWF

The over-use and pollution of Earth’s natural resources have become so extreme that, at current rates, a second planet will be needed by 2030 to meet the world’s needs, a new report warns.

The planet’s 6.8 billion people were living 50% beyond Earth’s sustainable means in 2007, the latest year for which figures are available, according to the biannual “Living Planet” report by WWF, a conservation group previously known as the World Wildlife Fund.

“Even with modest U.N. projections for population growth, consumption and climate change, by 2030 humanity will need the capacity of two Earths to absorb CO2 waste and keep up with natural resource consumption,” the report says, adding that four and a half planets would be needed if everyone used as many resources as the average American.

Study measures Atlantic plastic accumulation

A study has measured the amount of plastic debris found in a region of the Atlantic Ocean over a 22-year period.

US researchers, writing in Science, suggest the volume of plastic appeared to have peaked in recent years.

One reason could be tighter marine pollution rules that prevent vessels dumping their waste at sea.

The team said monitoring the free-floating plastic also provided an insight into the behaviour of ocean surface currents.

They found plastic, most pieces measuring no more than a few millimetres, in more than 60% of 6,136 samples collected by dragging fine-meshed nets along the ocean’s surface.

“Plastic marine pollution is a significant environmental concern, yet a quantitative description of the scope of this problem is the open ocean is lacking,” they wrote.
