The report added that now only a quarter of land on this planet has not been severely impacted or damaged by human activity, but is projected to decline to just one tenth of the land by 2050, due to pollution, disease, and climate change, among other factors.
It further added that South and Central America suffered the most dramatic decline in vertebrate populations - an 89 per cent loss in vertebrate populations compared with 1970.
At the Northumbrian Hedgehog Rescue Trust just outside Morpeth, where a team of volunteers cares for hundreds of sickly and underweight specimens every year, they fear the species is heading for extinction.
"These are hard times. Nature globally provides services worth around $125 trillion a year. we need more research, efforts from government, business and financial sectors, researchers and conservation communities to revive the planet", said Ravi Singh, Secretary General and CEO, WWF-India.
Leslie also said Canada has committed to new land protections the size of Alberta by 2020, and if it's done right, the country could make "meaningful progress" on protecting Canadian wildlife.
WWF United States President Carter Roberts said it was time to balance consumption with the needs of nature. 'The collapse of wildlife populations over the last half-century is a shocking measure of humanity's impact on our planet, ' John Sauven, executive director of Greenpeace UK, said in response to the report, joining WWF in calling for 'urgent action from world leaders.' 'From the decline of orangutans due to deforestation for palm oil to the ruinous impact of climate change on Arctic habitats to plastic pollution destroying marine wildlife, we can not continue with business as usual, ' he added. "In some cases, especially in marine environments, over-exploitation and overuse are the drivers of the decline of these species", he said.
Only a global pact on the scale of the Paris Agreement on climate change will save the natural world from irreversible collapse, the World Wide Fund for Nature (WWF) said after publishing a report showing a cataclysmic decline in global wildlife populations. The report points out that from 1970 to 2014 humanity has wiped out nearly 60% of mammals, birds, fish and reptiles.
"We have an opportunity to design a new path forward that allows us to co-exist sustainably with the wildlife we depend upon", he said. "Only by addressing both ecosystems and climate do we stand a chance of safeguarding a stable planet for humanity's future on Earth."Many scientists believe the world has begun a sixth mass extinction, the first to be caused by a species - Homo sapiens".
The report authors suggest three steps for improvement and called on decision-makers at every level to take action. Globally, natural resources are estimated to provide services - for example, pollination of plants - worth 125trillion USA dollars (£97trillion) a year. We need a healthy planet to have a healthy humanity.
The report also recorded a rise in ecological footprint or consumption of natural resources by 190 per cent in the past 50 years. The U.N. warned climate change poses "an urgent and potentially irreversible threat to human societies and the planet" that will "require rapid, far-reaching and unprecedented changes in all aspects of society".
