I wish everyone would stop eating meat OP yes, but a govt 'ban' isn't the way. People have to realise this for themselves.
Eating beef is so entrenched in the Western psyche. Our capitalist societies refer to cows as 'livestock' - basically economic units. Cows are reared and slaughtered outside of cities. Out of sight, out of mind.
Of course the beef industry doesn't want people to know that the carbon and methane emissions as a result of the beef industry are greater than the whole airline industry - globally. Of course they don't want people to reflect on the complex social relationships between 'livestock' - but how modern farming practices routinely separate mothers and calves. I won't go into what happens to male calves. Dairy cows are milked dry and then slaughtered as they have no economic use.
In Hindu India, by contrast, there is no tradition of eating beef. The cow is sacred - the mother - providing milk which is believed to produce calmness and wisdom. Why eat the cow meat when the same nutrients are in milk and so many foods can be made from milk. Eating cow meat is seen as producing stress and anger in humans - leading to war, psychological and physical illness.
The meat industry is the evil of the world. But people don't question it. Most people don't want to know. Nobody questions the logic of why we eat cows and sheep, but not horses or whatever. Humans insist on putting animals in categories and that's it, most people just accept it or forget to question why. Maybe in another hundred years, most people will have woken up?
Regardless, the meat industry will have to drastically downsize. Those involved will one day be called to account. It is an ethical and ecological nightmare. But what is happening now, is rather than take responsibility, the meat industry (in conjunction with pharmaceutical companies only too keen to cash in) is trying to reframe itself as the 'solution' - ie. "Look we can give cows these hormones so they produce less methane, Look everyone 'carbon free cows! Yay! Buy our beef, don't buy theirs. Look at us - we are the climate saviours."
So while consumers are distracted with the of issue 'which type' or 'which source' of beef to buy, methane emissions overall are soaring and conditions for cows becoming more horrendous. Because even though methane emissions per cow may be falling, overall methane emissions are higher than ever - because reducing methane is too often synonymous with hormones that mean a cow matured and is therefore slaughtered faster. Meaning more cows in their place and the industry can accelerate even faster. More methane globally. More rainforests cleared for grazing land. Humanity looks the other way and goes to Tesco.
