Since the beginning of life basically, there has been a foodchain, which generally if not interfered with, can remain the same for a long time. but since the arrival of modern homosapiens, we've drove many many animals to extinction, for food when we were primitive, which there was no problem with. but now, we have a stable method of farming animals for meat. what i'm focussing on is animals such as big cats, bears, crocodiles etc, animals that could kill us easily, animals in which we only kill for sport and in the odd instance, self defence. My question is basically, as the worlds population steadily grows, and industry expands, is there room for humans and wild animals to exist? I know we can probably prevent wild cats from going extinct what with cloning and such, but in my honest opinion, i can't see tigers, lions etc start to flourish again as a species. I heard recently that the black rhino was hunted to extinction recently, it's a horrible thing to hear, but i don't think it will directly affect our food chain. This may sound cold, but in the future it may be that we only keep the animals we need, not everyone cares about the preservation of a species, or the fact that it has took millions of years to evolve to this and we can so easily wipe it from existence. Such as the freshwater croc i think (might be saltwater) was almost wiped out a while back, which would be such a shame as they are probably the most successful animal on the planet as far as survival goes. I would personally love to see a way in which we could co-exist. and i have a particular fondness for big cats, i think they are amazing animals. but it may be that down the line there just wont be room for them to live with us, or foodchains will become so disrupted that even if we tried to introduce them back to certain areas they probably wouldn't survive anyway.
