Wildlife fell by 60 percent globally in 40 years, says the World Wildlife Fund

The World Wildlife Fund has released a report saying it has found a “surprising” 60 percent decline in wildlife globally over the past 40 years, mainly due to human activity, including climate change and habitat loss.

“This report sounds a warning about our arc. Natural systems necessary for our survival – forests, seas and rivers – remain in decline. Wildlife around the world continues to decline,” says WWW WWW. Carter Roberts, CEO and CEO -USA. “It reminds us that we need to change courses. It is time to balance our consumption with the needs of nature and to protect the only planet that is our home. “

The group’s two-year report, released on Monday, said that the measured trends in 1

6,704 populations of 4,005 species of birds, mammals, reptiles, amphibians and fish. The biggest falls were among creatures living in fresh water, which faced an even Greater 83 percent decline. South and Central America was hit hardest when the rainforest shrunk, with 20 percent of Amazon’s disappearance.

“Man and our way of feeding, burning and financing our societies and economies are driving the nature and the services that drive and supports the report, “reports the report.

Human activities have affected oceans, forests, coral reefs, wetlands and mangroves.” The globe has lost about half of its groundwater corals over the past 30 years. “

” From rivers and rainforests to mangroves and mountainsides worldwide show our work that the abundance of wildlife has fallen dramatically since 1970 “, s a Ken Norris, a science teacher at the Zoological Society of London, who gave one of three indexes used to write the report. “The statistics are scary, but all hope is not lost. We are able to design a new way forward that will enable us to live together with the wildlife we ​​depend on. Our report describes an ambitious agenda for change.” [19659002] As an example of the trend, temp. University biologist S. Blair Hedges reported Tuesday in the Proceedings of the National Academy of Sciences that he and a research group had found a close-total loss of Haiti’s primary forest and a mass of extinction of species. Hedges and his colleagues reviewed aerial photography and Landsat photos from 1988 to 2016 and found that the forests covered 4.4 percent of Haiti’s land in 1988. It dropped to 0.32 percent before 2016.

John Cecil, deputy president of stewardship at New Jersey Audubon, said he had not yet seen the World Wildlife Fund report, but was in line with previous research.

“We find a wide decline in species across the board,” said Cecil and noted exceptions, such as white-tailed deer and Canada geese. “There are many species out there, not threatened with immediate eradication, but compared to 50 or 100 years ago, their populations have fallen dramatically.”

Previously, habitat loss was by far the biggest driver of art loss, he said. Now he quotes climate change and invasive species as among the main reasons. Both change the habitat, for example, of birds who can no longer find the insects they once fed or planted the life they were due to, because “they are all coherent.”

“The birds fail where the non-native species take over,” said Cecil. “We see great changes. These global trends are consistent in the United States and the East Coast. “

More positively, the World Wildlife Fund reports that habitat recovery and other measures have worked, referring to population increases in giant pandas, mountain trout and threatened dolphins

It identified the 1973 American Eutrophication Act as helping” estimated 99 percent of listed species avoids extinction. “

Among other findings:

• Habitat suitable for mammals decreased 22 percent from 1970 to 2010, with the largest drops in the Caribbean, where it exceeded 60 percent.

• The index as Measures the extinction risk of birds, mammals, amphibians, coral and cyclades (an old group of plants) showed decreases for all groups, with species moving faster against eradication.

• People have already driven some areas beyond the borders through climate change, loss of biosphere, nitrogen and phosphorus flows and change of land use. [19659002] • Nineteen procedures nt of the world’s seabirds is estimated to have plastic fragments in the stomach.
