Species Extinction: Do We Really Need It?

Our Earth is full of coloured creatures like insects, birds and cool amphibians. But why to extinct them? Are We too selfish?There have been many hundreds of anthropogenic extinctions in the last 500 years. Some examples indicate the extent of the extinction problem. In mammals, 76 species such as the Steller sea cow are extinct, 2 extinct in the wild (i.e. surviving only in captivity, SOC hereafter), and 29 possibly extinct. At least 134 birds, such as the passenger pigeon (Ectopistes migratorius) are extinct, 4 are SOC, and are 15 possibly extinct. Amphibians have been severely affected, and 159 such as the golden toad (Incilius periglenes) are extinct, one SOC, and 120 species are possibly extinct. In the case of reptiles, 21 species are considered extinct and one SOC, whereas among fishes 91 species are considered extinct.
