Extinction of animal or bird species in the food chain may alter the physical environment as well. Animal extinction is far from a new ecological phenomenon. However, its not possible to determine the exact number because we only know about a small proportion of the species living on our planet, and this figure evolves constantly. Since the number of species on Earth is an ambiguous approximation, it is challenging to accurately quantify how many species are becoming extinct.
