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.
You’re thinking like a production line instead of like an ecosystem. You were produced and are sustained by an ecosystem, as are all production lines you can think of. If you stop assessing your and mitigating destruction of the ecosystem, you and everything you care about will be destroyed when the ecosystem, which sustains you and everything you care about, stops being capable of sustaining.
