By my opinion all species are very important. In last centuries especially in last hundred years due by human activity. Each being is a masterpiece of nature made by it in millions year. It is a sacrilege to extinct a species because that disappear for ever. The humans haven’t the right to extinct any species.
We need be conscious that humans occupy the areal of animals and disturb them. We must live in harmony with animals and only this ensures the future of human being.
