Also from the evolutionary biology perspective - top of food chain is the worst place to affect anything. These top pedators depend on all the bottom clogs to spin well, and if they dont, almost always top of food chain suffers. Dinos were wiped because they were just too big to handle suffocation, there prey (for carnivore dinos) were either dead or in burrows which they could not access. One of the only good top of food chain members are sharks - because they are just built good and still have large varied diets, and it is not like all shark species have survived.
I live in a country where 10s of millions died, due to partition. So i have seen blood. And what were believes of the people who saw it first hand - just stop where we are and restart building from here. The thing is, we believe violence can solve everything, it is the last weapon of game, that when we pick, we end story there, but that is not always the case, believing that violence is last resort - is also very naive according to me - From a fellow naive. Consider this a goodbye from me for today, hope to meet you in some other post (or irl) someday.
