I’m not saying that we should let bees or sheep or any important animals that benefit humans and the ecosystem. But why the hell do we need to maintain wild animals such as tigers and dolphins if they don’t provide food or material for engineering. Seriously why do we need to save some obscure endangered animal if the species itself is deadly too, which is a problem for humans and livestock. It’s okay if the species dies out, we don’t need to make a big fuss about some fuckass animal going extinct. It’s a part of nature and history, nothing will remain the same for centuries.
Because if you kill all the lions, gazelles will start overpopulating and eat all the grass which will starve them as they will run out of grass as well as all the creatures that eat the gass. This will also harm the creatures living in the grass as well as they will not have shade and will be easier to spot by predators wanting to eat them. This will cause the prey to decrease in numbers which will starve the predators. If the predators exist for those predators they will also decrease in numbers.
