The difference is that many plants bare fruit with the intention of being eaten and this is why a lot of food can be harvested with out harming the plant. Animals are meant to eat the fruit and the seeds are then expelled and therefore spread out after digestion.
On top of that, animals are usually over breed and live under horrible conditions before they are killed.
Either way it is a step in the right direction. Plants are living too but certainly they are the lesser of two evils. Any willful step anyone can take to save a life is a good thing. The best (as in less harmful) diet would be to be a breathatrian. But that is not practical for the majority of the population so we do the best of what we have/can do.
