With all due respect, without evidence your argument is baseless. I think your appealing to your ethos to persuade others (and on the internet what authority do you have?). I agree the world population should stop eating animals, but why?

My reasons are:

(1) morally dubious -- the majority of animals raised to be eaten live in squalor. It is below me, personally, to eat an animal raised in those conditions. For many people it isn't AND this doesn't support the argument that not eating animals is better for the planet.

(2) environmental impact -- the UN put out a list some years ago stating that to reduce environmental impact, consuming less animal and animal product is the way to go. Here is one list [0] indicting that among a collection of behavioral changes, eating more vegetables is helpful. Here is another [1] indicating that to reduce carbon footprint, travel (rather than diet) are primary ways to do so.

End of story? You must provide more than internet ethos to persuade an audience!
