@milkteethtv @ActualAkshay We are always hearing about extinct and endangered animals, but do you know what these terms actually mean? So, what is extinction? Extinction of a particular animal or plant species occurs when there are no more individuals of that species alive anywhere in the world - the species has died out. This is a natural part of evolution. But sometimes extinctions happen at a much faster rate than usual. For example, at the end of the Cretaceous period 65 million years ago, a mass extinction caused the death of many different types of animals and plants, including the dinosaurs.
