Humans caused over 25% of vertebrate deaths on land: Study

A study conducted by scientists in the US has found humans directly caused over 25% of terrestrial vertebrate deaths. Scientists examined about 42,000 deaths, between 1970 and 2018, which were reported in over 1,000 published studies and found that 72% died due to natural causes. "This is...one more example of the effect we're having on the planet," a scientist said.
