Humanity’s ongoing destruction of wildlife will lead to a shrinking (萎缩) of nature, with the average body size of animals     1     ( fall) by a quarter, a study predicts.

The researchers estimate that more than 1,000 larger kinds of animals will die out in the next century. They say this could lead to the collapse (崩溃) of ecosystems     2     are important for humans to get food and clean water.

Humans     3     ( destroy) most large animals from all inhabited (有人居住的) continents apart from Africa over the last 125,000 years. This destruction will speed up     4     (rapid) in the coming years, according to the     5     (late) research.
