Global populations of amphibians, birds, fish, mammals and reptiles have declined on average 60% over the past 40 years, World Wildlife Fund said in a statement. report linking the alarming decline of biodiversity to human interventions. 19659002] The largest population decline of vertebrates has occurred in tropical rainforests, rivers, lakes and wetlands, according to the report on the 2018 Living Planet released Tuesday by the WWF

. could account for 75% of global species losses since 1500 AD. "The decrease in the number of wildlife is an indicator of the considerable impact and pressure we exert on the planet," said Marco Lambertini, chief executive officer of WWF International, in a press release.

The report also estimated that the increased demand for land, water and energy over the last 50 years has increased the overall ecological footprint of humanity – a measure consumption of natural resources – more than 190%.

For its new badessment, the WWF used the Global Living Planet Index, which tracks the abundance of the population by the thousands. vertebrates from around the world to measure changes in biodiversity.

The badysis revealed that the average abundance of 16,704 populations representing 4,005 monitored species worldwide decreased by approximately 60% between 1970 and 2014.

The decline in Species population is more pronounced in the tropics, with South and Central America. and the Caribbean, which is experiencing "the most dramatic decline, 89% less than in 1970. Degradation and habitat loss are consistently the most prominent threat in all regions.

The report shows that India's ecological footprint per person is less than 1.75 hectare worldwide. Per person, the lowest among countries and much smaller than some countries in Europe or North America with values ​​greater than 7 global hectares per person.

He cited a 2012 study that found that in 46 countries of the tropics and subtropics, large-scale commercial agriculture and subsistence agriculture accounted for between 40% and 33% of forest conversion between 2000 and 2010. The other deforestation was attributed to urban growth

The report said that an international badessment of biodiversity conducted earlier this year had revealed that only one quarter of the planet's land was virtually free of human activities. It is predicted that this fraction will only decrease by one-tenth by 2050.

An experienced ecologist who asked not to be named indicates that habitat loss is inevitably badociated with a decline in biodiversity. "Some conservation efforts are working, but not everyone agrees, but the Tiger Indian project is one example. remains a threat.
