"[quote]Prey without their predators does more harm than good"? How do these statements even seem sensible to you? Firstly, we are not the natural predators of cows, pigs, chickens and lambs. You made a patently false and unsupported claim. Provide a source to back it up. Secondly, these are not animals we simply pluck out of the wild -- we breed them in specialized farms. They have no effect on the ecosystem whatsoever (except for the greenhouse gas emissions, which obviously doesn't work in your favour).[/quote] Predation: Noun "A form of symbiotic relationship between two organisms of unlike species in which one of them acts as predator that captures and feeds on the other organism that serves as the prey." Do we not capture (farm houses) and feed on these organism? That sounds like a predator to me. [spoiler]sorry I missed this when reading this the first time.[/spoiler]
