MOSCOW, Sept. 10 — Scientists analysed data on more than 4,000 species of mammals, birds, reptiles and fish and recorded an average decline in their populations by 68 per cent in 46 years, reported Sputnik news agency. “The global Living Planet Index (LPI) continues to decline. It shows an average 68 per cent decrease in population sizes of mammals, birds, amphibians, reptiles and fish between 1970 and 2016,” the World Wildlife Fund (WWF) said, according to a report they published.
“A 94 per cent decline in the LPI for the tropical subregions of the Americas is the largest fall observed in any part of the world,” it said.
The Living Planet Index (LPI) reflects the state of global biological diversity on the basis of population trends of vertebrate species worldwide. It is published every two years since 1998.
