Real meat from animals is good for you
It’s objectively bad for you in the quantities eaten by the west. Cutting out red meat, milk and most of the other animal products from your diet is measurably better for your health.
Stop giving billions to giant multinational cattle farming companies. It’s just as large an emissions source as oil (which you can also stop funding directly by avoiding driving where possible and going solar-powered electric for the rest)
So stop giving money to giant agribusiness corporations to subsidize the most polluting food source. Got it.
If the entire world turned vegan would it make a difference?
…yes. Plainly and obviously. Most land use would be gone overnight. Deforestation would stop immediately as would the second largest source of methane, one of the largest sources of NO2, and billions of tonnes of CO2 per year (about a quarter of all emissions). No other single initiative other than maybe ending urban driving would come close.
If you’re in the global top 50% there is absolutely nothing stopping you from switching to a primarily plant based diet, and if you’re in the bottom 50% you probably don’t eat enough meat to be a major impact.
Smugly attempting to mock people who care about animal welfare doesn’t justify all of the other harms you are doing.
