Global wildlife could decline by 67 per cent by the end of this decade as a result of human activities, according to WWF’s Living Planet Report 2016. The report shows how people are overpowering the planet for the first time in Earth’s history and highlights the changes needed in the way society is fed and fuelled. According to the report, global populations of fish, birds, mammals, amphibians and reptiles have already declined by 58 per cent between 1970 and 2012, the most recent year with available data.
