As humans continue to expand our use of land across the planet, we leave other species little ground to stand on. By 2070, increased human land-use is expected to put 1,700 species of amphibians, birds, and mammals at greater extinction risk by shrinking their natural habitats, according to a study by Yale ecologists published in Nature Climate Change.

To make this prediction, the ecologists combined information on the current geographic distributions of about 19,400 species worldwide with changes to the land cover projected under four different trajectories for the world scientists have agreed on as likely. These potential paths represent reasonable expectations about future developments in global society, demographics, and economics.
 
“Our findings link these plausible futures with their implications for biodiversity,” said Walter Jetz, co-author and professor of ecology and evolutionary biology and of forestry and environmental studies at Yale. “
