Scientists have calculated how many mammals might be lost this century, based on fossil evidence of past extinctions.

Their predictions suggest at least 550 species will follo the footsteps of the mammoth and sabre-toothed cat.

With every “lost species” we lose part of the Earth’s natural history, they say.

Yet, despite these “grim” projections, we can save hundreds of species by stepping up conservation efforts.

The new research published in the journal Science Advances, suggests that humans are almost entirely responsible for extinctions of mammals in past decades. 

And rates will escalate in the future if we don’t take action now.
