“If half the animals died in London zoo next week it would be front page news,” said Professor Ken Norris, ZSL’s director of science. “But that is happening in the great outdoors. This damage is not inevitable but a consequence of the way we choose to live.” He said nature, which provides food and clean water and air, was essential for human wellbeing.
The study analyzed 10,000 different populations, accounting for 3,ooo species. The researchers then used the data to create a first-ever ‘Living Planet Index’ (LPI), which gives a snapshot of all known 45,000 vertebrates.
Summarized in The Guardian, a second index in the new Living Planet report calculates the “ecological” footprint of the world’s nations. The repport concludes that humans are
— cutting down more trees than we replace
— catching more fish in our oceans than we restock
— pump more water from rivers and aquifer than rainfall can replenish
— emitting more climate-warming carbon dioxide with fewer forests and oceans to absorb them
In a shocking conclusion, the report concludes that at the current rate of global consumption, Earth needs 1.5 of itself to sustain our futures. In the case of US rate of consumption, 4 Earths are required to sustain our futures. The UK weighs in at 2.5.
