The World Wildlife Fund has released a report stating that over the last 40 years, a "staggering" 60 per cent decline in wildlife populations worldwide has been reported, mainly due to human activities, including climate change and habitat loss is.
Report sounds a warning shot over our bow. Natural systems that are essential to our survival – forests, oceans and rivers – are in decline. Wildlife around the world is dwindling, "said Carter Roberts, President and Chief Executive Officer of WWF-US. "It reminds us that we need to change the course. It is time to reconcile our consumption with the needs of nature and to protect the only planet where our home is located.
The group's biennial report released on Monday reported the development of 1
"Humanity and the way we feed, fuel and finance our societies and economies fuels nature and the services that drive us and support us to the limit," the report said.
Human activity has affected oceans, forests, coral reefs, wetlands and mangroves. The globe has lost about half of its shallow water corals in the last 30 years.
"From rivers and rainforests to mangroves and mountainsides around the world, our work shows that the abundance of wildlife has fallen dramatically since 1970," said Ken Norris, scientific director of the Zoological Society of London, who added one of three indices to the Provided that were used to create the report. "The statistics are scary, but all hope is not lost. We have the opportunity to develop a new path forward that enables us to live sustainably with the wildlife we rely on. Our report contains an ambitious agenda for change. "
As an example of this trend, Temple University biologist S. Blair Hedges said Tuesday in the Proceedings of the National Academy of Sciences that he and a research team had come close – the total loss of primary forest in Haiti and a mass extinction of species. Hedges and his colleagues studied aerial photographs and Landsat images from 1988 to 2016 and found that in 1988, 4.4 percent of Haitian land was covered by forests. In 2016, they dropped to 0.32 percent.
John Cecil, Vice President of Stewardship, New Jersey Audubon said he had not yet seen the World Wildlife Fund report, but he was in line with previous research.
"We are experiencing a broad decline in species across the board," Cecil said, noting exceptions such as Whitetail Deer and Canada Geese. "There are many species that are not threatened with extinction, but their populations have fallen dramatically compared to 50 or 100 years ago."
Previously, habitat loss was by far the biggest driver of species loss. Now he calls climate change and invasive species as one of the main causes. For example, both change the habitat of birds that can no longer find the insects that once fed them, or the plant life on which they were dependent, because "they are all interconnected."
"The birds are failing to take over non-native species," Cecil said. "We are seeing big changes, and these global trends are consistent across the United States and the East Coast."
More positive is the report the World Wildlife Fund, which said that habitat restoration and other measures were successful, with population growth being led by giant pandas, mountain gorillas, and endangered dolphins.

Among other things:
• The habitat suitable for mammals declined by 22 percent between 1970 and 2010, with the largest declines in the Caribbean, where it exceeded 60 percent.  • Extinction Risk Measurement Index for Birds, Mammals, Amphibians, Corals and Cycads (an old plant species) group) showed declines for all groups, with species moving more rapidly to extinction.
• Climate change, the loss of the biosphere, nitrogen and phosphorus flux, and land-use change have already pushed people beyond their borders.  002] • It is estimated that ninety percent of the world's seabirds have plastic parts in their stomachs.
