All 10 of the largest U.S. meat and dairy companies have lobbied against environmental and climate policies, resisting climate regulations, including rules on greenhouse gases and emissions reporting. This is according to a study by New York University, which examined the political influence of the 10 largest meat and dairy companies in the United States.
I don't know under which rock you have been living, but this is exactly what has been happening at a super rapid pace the last few years. I am not sure where you are from, but where I am from the vegan sections in the supermarkets are growing super fast with new and new vegan restaurants are popping up left and right.
Take this for example: https://plantbasednews.org/news/economics/lidl-vegan-food-price-meat-equivalents/ https://plantbasednews.org/news/economics/plant-based-food-retail-sales-record/
Also, it's always non-vegans who complain about what vegans should do. The world is dying, hundreds of millions of animals are killed each day and vegans are trying every fucking thing they can to try and stop the hurting. Let me tell you: vegans are out on the streets demonstrating, forming political parties and lobbying, transforming the food sector, doing medical research to show the (nearly entirely positive) effects of the diet, creating recipes and cookbooks, opening restaurants, helping people make the transition, doing critical animal studies, making documentaries, going undercover in slaughterhouses and factory farms, trying to get lab grown meat onto the market, arguing on the internet, etc. You've got no clue how much effort is being expended to try people like you to stop being part of the problem. How about you taking some responsibility? We'll keep trying in the mean time.
