To review:

The actions of humans as natural selectors for other species and the environmental changes, which are caused by the humans.

Introduction:

Human beings out of all the other species act as natural selectors in setting up the environment for other living. Over the years, people have caused much damage to the environment and thus created hostile living surroundings for other species. Many species became extinct because of the actions of human beings. Also, human beings by using antibiotics and excessive use of pesticides caused damage to crops and surroundings and a paved path for the generation of germs and decease, which are superior to the antibiotics. Thus, human beings are acting as the natural selectors for other species.
