Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? In my own opinion No but as u read more about it some things need to be preserved. For instance animals help the crops of the foods that we eat. Snakes help to cure different diseases. Humans help the plants and animals to grow. The fact that human beings are a species means that they depend on many other species that exist in the world. If an animal becomes extinct, this can have a knock on effect to other species, and humans would inevitably be affected by the species becoming extinct. Humans also have a built in instinct to survive, as do other species of animals. It is not surprising, therefore, that humans feel the need to try and extend the life span of some species, as they would probably feel that if it came to it, that something would try and prolong the existence of humans.
Humans should be concerned with the extinction rate, because the human population is growing and we need all the air, land, and animals to survive. There are humans that don’t quite understand that we have to preserve our land because we will be extinct sooner than later due to our big population.
