You can't. You would have to

  • get everyone to convert to vegetarianism (and there would have to be enough cultivated land to support them all)
  • get people to agree to allow pests to eat up their farm and garden plants and vegetables--starving people to save the animals
  • get labs to agree to test all products and pharmaceuticals on people
  • stamp out sport killing (easiest to start)

and much, much more. Maybe you could work on the last and least justifiable of those practices--sport killing--and try to make a difference there.

Well, if we don't convert everyone to vegetarian soon the world will be over - polluted and we'd all die (meat is the #1 cause of global warming, it is 18% - transport is 13%).

Global extinction of humanity would require more than global warming. We may need to rearrange our countries, and a lot of people may die, but extinction is very unlikely.

On topic, it is worth noting, that herbivores exist to remove plants and to be a food source for carnivores and omnivores. If herbivores were not eaten, they would basically loose their place in the food chain, and a large part of their reason to exist.

For as long as mankind continues to belong to the omnivores, it is unreasonable to assume that we would stop killing animals. Especially while there are still parts of the world, where animals are the only real source of certain proteins, vitamins and minerals, and where people to this day barely are able to scrape by.
