"Third largest" meaning it's not the number one like you stated in your original post.
I mean, I'm posting facts here. You're slinging crap.
You want to know what else will help the climate before you go removing cows from the equation? Recycling the hell out of everything. Now, explain to me why we as Americans cannot (or will not) recycle the living **** out of #1-7 plastics? Or the cardboard Amazon boxes you probably regularly throw out? (which emits methane, by the way) Or any number of metals, computer boards, ABS plastics and anything other than organic materials?
You see, we, as a country, don't recycle quite as much as we should. Furthermore, we send a whole metric ****-ton (like actual metric tons) of our plastics overseas where it's recycled. Why is that not an organic industry here that's working overtime?
Furthermore, why do we limit the types of plastic at most recycle centers? In my local single stream recycle area, I'm limited to #1 and 2 plastics, paper, cardboard, steel and aluminum cans. Oh, and no shredded paper, no #5 polypropylene (which is a VERY common plastic found in our society), no plastic shopping bags, no oversize items, no ABS plastics, no #6 Styrofoam (again, extremely common) no appliances regardless of size.
You want to make an environmental impact? Start recycling like Germany does. I actually limited myself to a single plastic shopping bag of garbage per week. Everything else was put into the yellow recycle bags (including potato chip bags) or into the paper bin (which included all forms of paper, they just shredded it regardless if it was paper, carboard or paperboard) and removed every week.
Ask yourself why we:
1) export a lot of our recycling
2) don't encourage recycling more at the local level (it can make a whole lot of money)
3) Don't focus on things that can be achieved easily like recycling instead of focusing on cow farts like your girl AOC.
