Why have so many animals gone extinct, what is the reason?
There are many reasons that can cause a species of animals or plants to become endangered, or even extinct. First of all, the human population has exploded since the last few decades. To accommodate the oversized human population more and more lands are taken away from these animals or plants. The natural habitats are snatched away from these species, leaving them only a small portion of the land, which they once roamed freely. With the little amount of land these animals or plants have, the food source become scarce. They have to fight among themselves in order to remain alive. They also don’t have enough room to live. Sometimes animals or plants don’t adapt to the limited space they now have, and die.
We’re in the middle of a mass extinction right now. The world has had a five mass extinctions before this one and it’s a natural process. Some species evolve and wipe out other species so different species can move into their niches. During this mass extinction, humans are the cause. We’ve polluted and destroyed countless habitats that animals need to survive. We’ve also hunted many species for their fur, tusks, etc. and that is a big factor as well. But in the past, natural catastrophes (i.e. that theoretical meteor that took out the dinosaurs), drops in sea level, global cooling (the ice ages), global warming (caused two mass extinctions before humans came to be), or when the oceans went through anoxia (lost all of it’s oxygen for a while) were all the main causes for mass extinctions.
