"Plummeting numbers of mammals, reptiles, amphibians, birds and fish around the world are an urgent sign that nature needs life support. Our Living Planet Report 2018 shows population sizes of wildlife decreased by 60% globally between 1970 and 2014.
For the last 20 years, scientists from ZSL, WWF and other organisations, have been monitoring changes in the populations of thousands of animal species around the world. Sadly, they’ve concluded that the variety of life on Earth and wildlife populations is disappearing fast."
An important paper published by WWF that TWIMC urges you to read.
