How would the world be different if everybody was vegetarian?
if everyone wanted to be a vegetarian, a lot of areas with foresting or jungles would have to be cut down for agricultural purposes. growing crops and growing food requires a lot of land for farming. not to mention the world would need a lot of chemicals to grow enough crops at such speeds. so food will be ten times more unhealthy because of that. you could go for a private garden, but lest we forget half of this world don't have enough food to eat or a house to sleep in. right at the moment that people wanted to be vegetarians, there would be a lot of food wastage of meat and fish. and also in case you don't know what "vegetarian" means; it means you eat only vegetables and no meat. HOWEVER, you may eat eggs, milk etc. because those are all PRODUCTS of animals and only VEGANS don't eat those.
