becoming a vegetarian should stop killing more animals

Nobody is fool enough to think that being a vegetarian will stop murder of innocent people, er animals.

But you have many reasons to be vegetarian and for myself, the animal welfare was not top of the list or even Number 2, 3, or 4.

Many people don't like the flesh texture or smell. Others dp it for religious reasons.
It's up to you if you are being vegetarian for the sake of saving or at least helping to stop killing some animals. The meat industry is the largest in the world, so it would take 100 years or so so change it. The same as slavery used to be, but bigger and more entrenched in people's lives.

Simply put, there are so many people in the world who eat animals and it's going to take a long time to change them all IF that is what you're after, to stop all animals being killed for meat.

If there were 4 people on the planet and 2 of them were vegetarian, then by reasonable argument, there would be fewer animals killed.

So in theory, you are going to be making fewer animals die. IN theory. The disgusting truth especially in USA is that SO MUCH FOOD is wasted. thrown out. In other countries this would be illegal.
You are making a difference. First to yourself, second to the greater cause.If one more person in this town became vegetarian today, and repeated throughout America and the actual world, then there would be a difference. A big one.
Butyou need to do this for your own reasons first. If you do not believe n yourself, it doesn't matter what you do.
