Re: what Vegans think will happen to all those animals we breed for food and dairy
And to do that we would need to increase our crop manufacturing. Granted the land used by breeding livestock could in some cases be used to grow crops, but when you use the land for crops then you are killing off the little animals that live in those lands happily co-existing with the livestock. Mice, moles, insects, birds etc.... not to mention the fact that use of pesticides would have to increase( and who knows what sort of impact that could have on the environment), and as much as you may not like it, gmo's would likely also be on the rise to meet the growing demands (or just to increase yields and make it worth it for the farmers).
Next, onto the human factor. Think of all the industries that would go out of business overnight if you stopped using animal products. We would have to increase the use of plastic to fill the gap. Our oil use goes up, the price of oil becomes more expensive. Not to mention the fact that we increase the amount of plastic waste we generate.
Way to save the world!
