Sure, some things could be replaced. But all? Not likely.
I'm not sure what you mean by this. If animals were left to their own devices, I'm wondering if the populations would grow too large due to the fact that humans would not be using them for food. Basically it's a question of whether there are enough natural predators to keep the population down.
^^^ This is another good example of what I was trying to illustrate regarding the cow cartoon, FullmetalHeart20.
The vast majority of farmers would just cull all their animals. They are so domesticated they would be hard pushed to survive 'in the wild' and the land they used to populate would be used to grow crops instead. There wouldn't be anywhere for them to survive, unless nature reserves were developed for them. Even then, with no form of population control they would eventually eat all the available food and starve. Nature is a fine balance. If any part of the food chain becomes too populous it runs out of food and the numbers drop again.
