True in many cases but not all, and the people managing these populations are almost never directly responsible for the problem. For example the species I now help manage in my country were introduced generations before my birth. Same for the overwhelming majority of the land clearing, it was done before even my parents existed.

I can't change history, but I can take some responsibility for mitigating the damage of those who came before me.

It's less about managed culls and more about raising funds for conservation.
