Killing endangered species will save them.

[The One and Only...]

You must realize, kelly, that this planet must already be tipped in favor of carbon dioxide. Between pollution, a much higher population of animals on earth, and a much lower population of plants, this planet has to get rid of carbon producers.

Would it not, therefore, be logical to kill off as many creatures as possible?

Species that are undesirable are species that cannot be used as food, etc.
