If you'd like to be arrogant about it then that's fine. However, we revolve around and are dependent on animals, insects and plants to provide us life.
>We evolved to expand; we're machines to replicate DNA.
You can expand as much as you want. Nature will fight back like it has with adaptive viruses and the Ice Age.
>You may want to save the environment so you can continue to live, but poaching elephants doesn't harm human survivability.
My comment dealt with saving humanity from humans. If you think it's fine to kill elephants while they hold a funeral then you've lost your humanity. Some already have. A bunch of 6 year-olds just got killed and NRA subscriptions went up during that span before any legislation.
