One million of the planet's eight million species are threatened with extinction by humans, scientists warned Monday in what is described as the most comprehensive assessment of global nature loss ever.The global rate of species extinction "is already tens to hundreds of times higher than it has been, on average, over the last 10 million years," according to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), a UN committee, whose report was written by 145 experts from 50 countries.Back to Animals Species of animals or organisms are considered extinct when there are no more of them alive.

Now is the time to act, not halfheartedly and incrementally but drastically and boldly." The IPBES report comes ahead of two high-level summits in 2020 where world leaders will scale up their climate and environment protection goals.

That is when China will host the UN convention on biodiversity to set new 20-year targets and when the signatories of the 2015 Paris Agreement to keep global warming to less than 2 degrees will revise their commitments.

Rachel Warren, professor of global change and environmental biology at the University of East Anglia, told CNN that governments should focus on "the restoration of destroyed or degraded ecosystems with native species [as this] helps to address both biodiversity loss and climate change.""Biodiversity underpins ecosystem services such as pollination, flood prevention, water and air purification, and soil conservation.

We are in danger of losing vital ecosystem services which will have major negative consequences for human civilization," she said.

More extinctions reduces the planet's biodiversity and can have adverse affects for all life on Earth.

Hunting Many species have been hunted to extinction or to the point where they are critically endangered. There were millions of bison in the Great Plains of North America until the arrival of the Europeans.Amur Leopard, a rare species of leopard living on the borders of Russia and China, was the winner of the 2013 WWF award dedicated to the positive evolution of an endangered species, but remains critically endangered.Leatherback turtles are the largest sea turtle species and also one of the most migratory, crossing both the Atlantic and Pacific Oceans.It notes that the world's population has more than doubled (from 3.7 to 7.6 billion) in the last 50 years, and gross domestic product per person is four times higher."[There is] very little of the planet left that has not been significantly altered by us," Sandra Diaz, co-author of the report and professor of ecology at the University of Córdoba, told CNN.Human Interaction Today many conservationists are concerned with human interaction causing species to become extinct.This is because human interaction has increased the rate of extinctions beyond what normally should occur in nature.Guenter Mitlacher, director of international biodiversity policy at the World Wildlife Fund (WWF), said, "Ours is the first generation with the tools to see how the Earth has been changed by people at our own peril.We're also the last generation with the opportunity to influence the course of many of those changes.Species that live only on islands can also be easily hunted to extinction.Even the arrival of a small tribe can quickly eliminate an island species.
