I heard something to do with Nitrogen and …cow farts(?) I am really unsure of this and would like to learn more.
Answer -
4 Parts
- Ethical reason for consuming animals
- Methane produced by cows are a harmful greenhouse gas which is contributing to our current climate crisis
- Health Reasons - there is convincing evidence that processed meats cause cancer
- it takes a lot more calories of plant food to produce the calories we would consume from the meat.
Details about the answers are in the comments
Also, hardly any cows just eat grass these days. That’s not how you get a lot of meat as fast and as cheap as possible. Also, since cows need a lot of grass, I a lot less area would remain for other crops even if they did (since grass needs way more area for the same amount of calories than stuff like soybeans). So it’s actually a good thing, they aren’t just eating grass.
Funnily enough, having cattle on that land only further fucks it up by causing erosion that can take decades to resopve even after the cattle is removed.
If that is the case, then they are more the exception than the rule. (Do you by chance have any source on that? Because I’m pretty sure here in Germany that’s not the case) Also, at least Switzerland produces less beef than it consumes, so that’s not exactly sustainable. I don’t know about the other two.
There are of couse exceptions and areas where cattle can graze all year, and the need to deforest areas isn’t as large as other places. However, for the majority of beef production, there are less enviornmentally friendly cattle food implemented. So maybe the solution should be that only the areas that can produce beef sustainably should be allowed to consume it? I would assume that that would be an unpopular policy, so I find it to be a much better solution to reduce the beef consumption even in the areas with sustainable producion and rather let those areas export the excess production.
