50 per cent decline in population of 3,000 species

About 3,000 species of wildlife around the world have seen their numbers plummet far worse than previously thought, according to a new study.

The study from the Swiss-based WWF largely blamed human threats to nature for a 52 percent decline in wildlife populations between 1970 and 2010. It says improved methods of measuring populations of fish, birds, mammals, amphibians and reptiles explain the huge difference from the 28 percent decline between 1970 and 2008 that the group reported in 2012.

Most of the new losses were found in tropical regions, particularly Latin America.

The study analysed data from about 10,000 populations of 3,038 vertebrate species from a database maintained by the Zoological Society of London. — AP
