The thing with 99% leverage sadly has only a chance of 1% to happen while the 1% leverage thing you can just make happen. And if you make the 1% thing happen in more people the votes for the 99% thing start to go up as well. And eating less meat does have an impact. For years now i read headlines that year n had less pig meat being eaten in total than year n-1 (pork being the focus as my country afaik does not have a big beef industry so it's not as relevant to report about it)

We have very little influence on the industry as a whole but if you buy less meat, the meat industry actually becomes smaller over time. The alternative products also become more and more. Super markets over here all have a vegan shelf at least and there's more vegan only restaurants opening up in my city that even made my meat eater colleagues go there to eat from time to time.
