The reasons for the extinction of species?

Before the beginning of human dominance on Earth, many species of flora and fauna disappeared. Natural disasters destroyed many aquatic species, after the fire that formed our atmosphere, incinerated plants on the planet, a huge asteroid destroyed the dinosaurs. Now species on Earth are disappearing due to human actions. More than three thousand species of animals and plants disappeared in the twentieth century, through the development of human civilization. Species disappear, because they have no place on our planet and if they do not adapt, they will recede into oblivion.
