Half of marine life wiped out in just 40 years, says WWF

Populations of marine mammals, birds, reptiles and fish have halved in the last four decades, environmental NGO the Worldwide Wildlife Fund (WWF) warned on Wednesday.

Australian researchers predict that plastic ingestion will affect 99 % of the world's seabird species by 2050.

Researchers from Commonwealth Scientific and Industrial Research Organization (CSIRO) and Imperial College London have assessed how widespread the threat of plastic is for the world's seabirds, including albatrosses, shearwaters and penguins, and found the majority of seabird species have plastic in their gut.
