What animals are going extinct because of human activities and what should be done about it?

There are many species going extinct because of the direct destruction of their habitats, such as building dams in the mountains where many wildlives already inhabit, or indirect devastation, such as contaminating their environments. For example, Corvus hawaiiensis, and Atelopus zeteki are now extinct in the wild. According to the pundits, there is little chance of recovering these animals in the wild because of their over-decreased population. However, there are still many things to do about critically endangered species, endangered ones, and vulnerable ones. They are confronted by urgent dangers, but with our care and interest, they can rebound to what they used to be. For instance, a tiger is classified as one of the endangered species. There were about 3,800 tigers left across the world as of 2017. They had been pursued for hunting or human exploitation. If we don’t do anything before it’s too late, we will only see them in zoos.
