A large number of species are whipping out every year, and this has imperilled Earth's ecosystem in a way that has never been experienced before. Although the protection of animals may seem absurd, when many humans are in a delicate situation; howerer, If one delves into this issue, from a broad perspective, one will come to the understanding, that all species are connected in our ecosystem, similar to a chain, and extinction of some can endanger others. The wolves are hunted by lions, whereas they hunt sheep. If wolves become extinct, there would be no food for lions, and sheep would clear all the grass that exists, which can cause a dusty storm. So the protection of animals has a chain of benefits, not only in favour of humans but also other species.
