RE: Plummeting insect numbers threaten collapse of nature
The UN has just released a 1,800 page report on the devastating impact of humans on nature. Some of the main points:
*Forests have been cleared at astonishing rates, especially in tropical areas *Only 13% of wetlands present in 1700 were still in existence in 2000 *25% of plants and animals are now threatened *About 1 million species face extinction within decades *Plastic pollution has increased 10-fold since 1980 *Every year 300-400 million tonnes (yes, tonnes) of heavy metals, solvents, toxic sludge and other wastes are dumped into the waters of the world *33% of fish stocks were harvested at unsustainable levels in 2015 The study urges the world to steer away from the "limited paradigm of economic growth".
