Humans are well known as super predators but for the first time scientists have put a figure on it.

We exploit around a third of all wild animals for food, medicines or to keep as pets, putting almost half at risk of extinction, they say.

That makes us hundreds of times more dangerous than natural predators such as the great white shark.

And they warn of profound consequences for whole ecosystems.

"The size and Scale of what we set up surprised us," told Doctor Rob Cooke of the united kingdom centre for Ecology and Hydrology in wallingford, oxfordshire

"Humans have a breath-taking diversity of uses of animals but we need to move towards sustainable human-nature relationships across the globe."

and fish that humans harvest for food, medicines or clothing, or collect from the wild for the pet trade.

They found we use or trade 14,663 species - about a 3rd of all vertebrates - and are operate 39% of these towards elimination.

And our impact is up to three hundred times larger than that of top carnivore such as the beautiful white shark, white lion or tiger.

now humanity has a bigger impact on different animals on the earth than at any time in history,

We are entering the Anthropocene, the time during which human activity has been the ruling influence on weather and the nature.

tame animals now make up the mostly of animal species on area, shaping the natural earth.

the researchers warn that continued overexploitation of wild animals will have "profound result for biodiversity and ecosystem function".
