Humans are set to drive 1,700 bird and animal species towards extinction by taking their natural habitat within the next fifty years, a study warns.
As humans continue to expand our use of land around the globe, could lose so much habitat that they would be at much higher risk of extinction.
By the year 2070, researchers have forecast that 1,700 species of amphibians, birds, and mammals will be threatened due to their shrinking natural habitats.
The study by ecologists at Yale University in Connecticut, shows how land-use changes will impact future biodiversity.

Species living in Central and East Africa, Mesoamerica, South America, and Southeast Asia will suffer the greatest habitat loss, according to the study.
The team examined different scenarios based on population growth and economic changes in global society that would warrant humans' increase in land use.
They then compared that to the geographic range of 19,400 species and found that 886 amphibians, 436 birds, and 376 mammals would lose so much habitat that they would be at much higher risk of extinction.
The research team said that the potential paths represent 'reasonable expectations' about future societal developments demographics, and economics.
Study co-author Yale Professor Walter Jetz said: 'Our findings link these plausible futures with their implications for biodiversity.
Man is poised to drive 1,700 bird and animal species towards extinction within the next 50 years, warns a new study. As humans continue to expand our use of land around the globe, we leave other species little ground to stand on. Here, the habitat of the Lombok Cross Frog lives
'Our analyses allow us to track how political and economic decisions - through their associated changes to the global land cover - are expected to cause habitat range declines in species worldwide.'
The study shows that under a 'middle-of-the-road' scenario of moderate changes in human land-use, about 1,700 species will likely experience marked increases in their extinction risk over the next 50 years.
The findings suggest that they will lose roughly 30 per cent to 50 per cent of their present habitat ranges by 2070.
Among them are species whose fates will be particularly dire, such as the Lombok cross frog in Indonesia, the Nile lechwe in South Sudan, the pale-browed treehunter in Brazil and the curve-billed reedhaunter found in Argentina, Brazil and Uruguay.

All of them are predicted to lose around half of their present day geographic range in the next five decades.
The projections and all other analysed species can be examined at the 'Map of Life' website.
The maps show the impact on species at a kilometer-scale resolution.
'The integration of our analyses with the Map of Life can support anyone keen to assess how species may suffer under specific future land-use scenarios and help prevent or mitigate these effects,' said Dr Ryan P. Powers, co-author and former postdoctoral fellow at Yale.
Species living in Central and East Africa, Central America, South America, and South East Asia will suffer the greatest habitat loss and increased extinction risk, according to the study.
But Professor Jetz cautioned the global public against assuming that the losses are only the problem of the countries within whose borders they occur.
'Losses in species populations can irreversibly hamper the functioning of ecosystems and human quality of life,' he said.
'While biodiversity erosion in far-away parts of the planet may not seem to affect us directly, its consequences for human livelihood can reverberate globally.
'It is also often the far-away demand that drives these losses - think tropical hardwoods, palm oil, or soybeans - thus making us all co-responsible.'
The findings were published by the journal Nature Climate Change.
'TIME IS RUNNING OUT': DAVID ATTENBOROUGH'S WARNING TO HUMANITY
Sir David urged action against global warming and called it a man-made disaster that poses 'our greatest threat in thousands of years'
Your excellencies, ladies and gentlemen.
'We the peoples of the United Nations'.
These are the opening words of the UN Charter.
A charter that puts people at the centre.
A pledge to give every person in the world a voice on its future.
A promise to help protect the weakest and the strongest from war, famine and other man-made disasters.
Right now, we are facing a man-made disaster of global scale.
Our greatest threat in thousands of years. Climate Change.
If we don't take action the collapse of our civilisations and the extinction of much of the natural world is on the horizon.
The United Nations provides a unique platform that can unite the whole world.
And as the Paris agreement proved, together we can make real change happen.
At this crucial moment, the United Nations has invited the world's people to have their voice heard, by giving them a seat.
The People's Seat; giving everyone the opportunity to join us here today, virtually, and speak directly to you the decision makers.
In the last two weeks, the world's people have taken part in building this address, answering polls, sending video messages and voicing their opinions.
I am only here to represent the 'Voice of the People': to deliver our collective thoughts, concerns, ideas and suggestions.
This is our 'We the peoples' message.
The world's people have spoken. Their message is clear.
Time is running out.
They want you, the decision makers, to act now.
They are behind you, along with civil society represented here today.
Supporting you in making tough decisions but also willing to make sacrifices in their daily lives.
To help make change happen, the UN is launching the Act Now bot.
Helping people to discover simple everyday actions that they can take, because they recognize that they too must play their part.
The People have spoken.
Leaders of the world, you must lead.
The continuation of our civilisations and the natural world upon which we depend, is in your hands.

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.
Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
