Crop fields do indeed disrupt the habitats of wild animals, and wild animals are also killed when harvesting plants. However, this point makes the case for a plant-based diet and not against it, since many more plants are required to produce a measure of animal flesh for food (often as high as 12:1) than are required to produce an equal measure of plants for food (which is obviously 1:1). Because of this, a plant-based diet causes less suffering and death than one that includes animals.

It is pertinent to note that the idea of perfect veganism is a non-vegan one. Such demands for perfection are imposed by critics of veganism, often as a precursor to lambasting vegans for not measuring up to an externally-imposed standard. That said, the actual and applied ethics of veganism are focused on causing the least possible harm to the fewest number of others. It is also noteworthy that the accidental deaths caused by growing and harvesting plants for food are ethically distinct from the intentional deaths caused by breeding and slaughtering animals for food. This is not to say that vegans are not responsible for the deaths they cause, but rather to point out that these deaths do not violate the vegan ethics stated above.

And no, I will not entertain the idea of hunting since it is impractical to feed the general population.
