If someone is really invested with the environment and climate, they should at the least have some awareness of the consequences of meat consumption. In that case, why do others have to keep holding their hand? The world wide web is full of delicious vegan/vegetarian recipes. Why does individual responsibility/initiative stop when one is convinced that reducing a luxury good is the best option?
And there are so many options to improve. Flexitarian, pescaterian, vegetarian, plant-based or vegan. I believe it helps to not let perfect be the enemy of good. It might also depend a bit on what convictions you want to change. If climate and/or health, it might give a bit more leniency; if animal wellfare it is likely to be a strict regime.
(keep in mind, the above is about those who say to care for the environement/climate)









I am pretty certain this is a hybrid.
