Vegetarians =.=

Question in mind - Why are there vegetarians in this world? =.=

Vegetarians say eating animals is bad. So they eat plants. BUT by eating plants they mengurangkan the rate of change of CO2 to O2 on earth =.= Rentetan itu, not only are they endangering the plants, they're also endangering the ANIMALS and US. And they say killing animals is bad *pfft* Rather kill them straight then indirectly kill them by suffocating and making them extinct alltogether. So why be vegetarian? Eat more MEAT(white meat. don't get fat eating too much red meat)and less GREENS. Help REDUCE GLOBAL WARMING. If you vegetarian people say that killing animals is wrong because it's a living thing, what about PLANTS? Go learn std 4 science =.=
