what will happen it everyone on earth become vegetarians?

Answer 1

Three immediate benefits:

1. More food for all. Why feed 20 lb of corn and soybeans to produce 1 lb of beef when the original 20 lb of food will do a much better job as food for people?
2. Less communicable disease among people, e.g. bird flue, mad cow disease.
3. Less obesity, heart diseases.

Answer 2

Science has proven time and again that humans do not require meat for their diet, vegetables can provide all the vitamins, minerals and nourishment.

Science has also showed how people on a high red-meat diet start showing extra symptons of violent and rude behaviour - this is exactly what the Hindu scripture Bhagavad-Gita foretells.

If everyone were to turn vegetarian then the whole society would stand a better chance of making real progress in all aspects of life.

Answer 3

Other species that eat meat would do so with less competition. Humans would become more regular (except for those who live exclusively on french-fries, corn chips and potato chips). Cows would still be raised for milk (assuming that lacto-vegetarians are permitted), chickens would still be raised for eggs (assuming that ovo-vegetarians are permitted), and fish and seafood would still be caught and farmed (assuming that pesce-vegetarians are permitted in your crazy little veggie-world). Animal rights people would have to find new jobs, so they'd probably start vegetable rights groups, and humans would ultimately be reduced to eating dirt.

Answer 4

All those domesticated animals that exist only because of humans eating them will become extinct, there will be many less wild mammals alive and the ecosystem will suffer. And the amount of methane in the atmosphere will increase because of all the farting that human vegetarians do, despite the lack of cows and sheep.

Answer 5

Domesticated farm animals will become extinct as they have been bread too much and now can't survive in the wild. Vegetarians are cruel to animals and should start eating them immediately for the creatures own good.

Answer 6

Most of our food animals would have to be killed because we'd need their grazing land for vegetable gardens.

Our loss of certain amino acids would cause our height to diminish, our longevity as well. Look at the faithful Hindu. Even the wealthy ones are neither so tall nor so healthy as a poor American who can get his/her hands on meat.

On the upside, there'd be less cow methane in the atmosphere. Of course, unless we all consumed Beano before every meal, we'd soon make up that lack.

Answer 7

The world would become over-populated by animals, humans would probably die out because 1. we need meat and 2. it would not be possible to cultivate enough vegitation for everyone, especially if there were more grazing animals, etc.
But then the animals we eat might die out too because no-one would continue breeding them if they served no purpose.

Answer 8

We will all have headaches, because there is a substance in vegetarian foods that increase the chances of migraine headaches.

Other than that we would probably be all healthy just with a lot of migraines.

Answer 9

i guess, and this is pure guess work, there would be more animals around, life can be cruel at times, and although i am abig meat eater, as was my brother ( he turned vegi, then vegan then back to vegi some 10 years ago now!!), the reason why we eat meat is because we do need the protiend in there, if there were 10000 cows in a town it woudn't be right it is always about balance, night thought tho' !!

Answer 10

The cows will take over the earth and there won't be enough land to plant vegetables for all of us to eat. I hardly think this will ever happen though.
