How much info have you looked at about it?Not convinced on this meat is bad for the environment but it is an easy target and vigorously promoted by big business.
Flying accounts for 2.5% of all carbon dioxide emissions, and yet nothing seems to be happening to reduce that other than offering those who can afford it carbon offsetting. For example when Harry and Megan took a 12 seater plane to the south of France (?) it kicked off a bit in the news and then Elton John payed the offset. About a 100 quid yippee the world is saved. Is that it? increasing the cost will just prevent the poor from travelling while the rich just get on with it. Also it's estimated that only 6% of the world population has ever flown, plenty of scope for that to increase.
I think if you do look into it then it is quite convincing actually.
