Why is it necessary to protect the biological diversity of living organisms?

Protecting species and taking care of biodiversity conservation is necessary because all organisms, regardless of their size and place in the food chain, are important and perform different functions within their communities. The loss of one species can entail irreparable consequences for a huge ecosystem and become disastrous for the rest of the species in this area too. In addition, the species we see now are the result of millions of years of evolution and must continue to evolve.
