In Ireland where there are a lot of sheep theyre an ecological disaster (if you think having biologically diverse forests is a good thing)

I mean I just said a fact, sorry if I upset you.

Obviously if someone needs to eat meat to live I'm not going to object. And people living sustainably and not just supporting the animal ag industry are also off the hook in my books.

But in regards to your weird vegetation stuff, I hope you're aware that the livestock are raised on vegetation and will typically consume more calories of feed than they provide with meat? This is a large part of why the Amazon is being deforested, it's to feed livestock, not vegans. The science on how to stop environmental damage is pretty clear on that one.

Is that a rule here??

Go vegan.

Let me guess, you're a westerner with access to plant-based dietary supplements? I suppose you're vegan then? If not, you must be part of some indigenous people.

Then maybe not cotton and instead hemp

Mate, I have three chickens at home and I feed them a scratch mix that is mostly grain. I think you’re talking out of your arse, and I strongly doubt you have any actual animal husbandry experience.

Animals products are less efficient for a simple energy reason. Animals produce heat which radiates away as lost energy, and they rely on consuming autotrophs. All life gets its energy from the sun, we as animals get it one or two down the food chain from plants or other animals (which are also eating plants). Animal-based products are simply less efficient.

Why it is true that you’ll graze non-butcher animals on the leftover stalks and such, we absolutely finish beef and pork on grain and a big portion of the grain harvest is for animal feed.

Food is grown specifically to feed livestock though, it would be a pretty weird trophic pyramid for them to survive on our waste unless you went back to a time where people killed their one pig for the year and salted it away. In our country, the land degradation from clearing hill country for grazing has led to enormous biodiversity loss and a self-fufilling prophecy of eroded weak topsoil that people claim isn't good for anything else (though it could still be rewilded and in other cultures and times would be terraced and swaled to support plant crops).

It's brought up because it's true.

research

edit: link doesn't appear to be working, but it's the paper by Emily Cassidy called 'redefining agricultural yields'

What you say is true for 5% of animal feed globaly.

Beef is fed (extra) soy. A lot of porc as well
