About 6 waves of massive extinction are known in the history of the Earth. The last one wiped out the dinosaur world 65 million years ago and was probably due to a meteorite collision.
But the recent one has no natural causes. It is man made and rampant, eliminating three animal or plant species every hour.
Scientists and environmentalists issued reports about threats to creatures and plants including right whales, Iberian lynxes, wild potatoes and even wild peanuts.

"Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted."
Human beings are part of the natural world, and we are causing species to die out. BUT this is exactly the process that the science of evolution supports.
