Our species now extracts 60bn tons of resources each year, almost double the amount in 1980, though the world population has grown by only 66% in that time. The report notes how the discharges are overwhelming the Earth's capacity to absorb them. More than 80% of wastewater is pumped into streams, lakes and oceans without treatment, along with 300-400m tons of heavy metals, toxic slurry and other industrial discharges. Plastic waste has risen tenfold since 1980, affecting 86% of marine turtles, 44% of seabirds and 43% of marine mammals. Fertiliser run-off has created 400 "dead zones", affecting an area the size of the UK.
