Eating meat is natural - this is how life rises above to the top of the food chain, and any Darwinista proclaiming it doesn't, is doing so for the sake of ignorance and argument.
Cremation on the otherhand is unnatural. This is a fact. Life is born and dies, decomposes naturally, resulting in fertile land, nourishing the next life - this is the order of life, and has been for donkeys years before man. Cremation is the complete opposite - doesn't nourish land, and ends the natural cycle.
Of course humans didn't become the dominant specie by eating grass; it did so by eating meat.
Cattle is the major contributer in 'greenhouse gases'. If they are not eaten, then the earth will end up like Venus. Then your Greta Thunbergs would have a meltdown.
Oh, anyone who is against eating meat most likely buys products derived from dead animals. Leather shoes, handbags, coats, and so on.
Don't pander to the Greta Thunbergs
Oh my, I do love proving you wrong.
So the 'natural' argument is an appeal to nature fallacy. I know you don't understand philosophy, but please try and keep up. Rape, infanticide, living in the forest, having harems, being opportunistic hunter-gatherers, etc are all natural. Does that make those things moral and correct? Being monotheistic isn't natural, living in houses isn't natural, modern medicine isn't natural. Shall we toss all of those things out?
Yes, eating meat was part of our evolution (though there are examples of plant-based diets in early humans
https://www.pnas.org/content/113/51/14674), but that doesn't mean it's necessary now. That's an appeal to tradition and an appeal to nature fallacy. Fantastic.
You seem to suggest that meat is necessary, well then you argue against the American Dietetics Association-
It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. https://pubmed.ncbi.nlm.nih.gov/19562864/
The cattle argument, oh my you're ignorant. Why are there so many cattle which cause such emissions? Because they're bred into existence. A transition to a plant-based diet would mean the demand drops. As the demand drops, the supply will drop. It's not hard. They will stop being bred into existence.
This Oxford study shows that a switch to a plant-based diet can reduce emissions caused from food by up to 71%:

Sorry, that is too much science for you! Run, hide, and complain about Greta like a boomer!
Well, no. Many people who advocate for not eating meat for environmental and health reasons also abstain for moral reasons, like myself. Therefore, they will not buy good which are derived from animal products. There could perhaps be some edge-cases like some technology being comprised of parts which may be animal derived, but it is very easy to not consume animal products in the form of food and clothing.
This movement was about far longer than Greta was prevalent. The scientific literature has been mentioning this for years. But yes, you'd not know anything about that!
Remember everyone, this is the person who said that evolution isn't real and that peer-reviewed, scientific journals say that science leads to god!
