answer.....
here is your answer dear....
We are destroying nature at an unprecedented rate, threatening the survival of a million species – and our own future, too. But it’s not too late to save them and us, says a major new report.
“The evidence is incontestable. Our destruction of biodiversity and ecosystem services has reached levels that threaten our well-being at least as much as human-induced climate change.”
With these words chair Robert Watson launched a meeting in Paris to agree the final text of a major UN report on the state of nature around the world – the biggest and most thorough assessment to date, put together by 150 scientists from 50 countriesThe report, released today, is mostly grim reading. We humans have already significantly altered three-quarters of all land and two-thirds of the oceans. More than a third of land and three-quarters of freshwater resources are devoted to crops or livestock.
Around 700 vertebrates have gone extinct in the past few centuries. Forty per cent of amphibians and a third of coral species, sharks and marine mammals look set to follow.
