Why do you think a growing human population means a mass extinction event for earth’s animals? cite your evidence.

Hello,

A “biological annihilation” of wildlife in recent decades means a sixth mass extinction in Earth’s history is under way and is more severe than previously feared, according to research. Scientists analysed both common and rare species and found billions of regional or local populations have been lost. They blame human overpopulation and over consumption for the crisis and warn that it threatens the survival of human civilization, with just a short window of time in which to act.

Hope this helps (:

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
