There will be more plastic by weight in the ocean than fish by 2050, a new report from the World Economic Forum and the Ellen MacArthur Foundation has warned today.

According to the report, The New Plastics Economy: Rethinking the future of plastics, between $80 and $120 billion of plastic packaging enters the waste stream each year, with significant environmental implications.

The report was produced, with McKinsey & Company as a knowledge partner, as part of Project MainStream – a collaboration between the Ellen MacArthur Foundation and the World Economic Forum, with analytical support from McKinsey & Company.
