For sure, but that applies to literally everything - decarbonization of the energy grid/moving away from gas is a huge factor for literally every aspect of life, particularly farming and red meat. The energy involved in creating meat is significantly higher than any other foods, which is why I disagreed with your point. We have an alternative for meat, but there isnt one for concrete. Using it as a comparison is a poor argument.

Arguing that conditionally essential amino acids are not found elsewhere is a misleading argument. In addition to the fact that all of those three can be created by your body, Taurine is found in lentils, a staple of many vegan diets, seaweed can contain creatine, and carnitine can be found in trace amounts in most foods. None of them are as dense as meat, for sure, but there are numerous sources, plus supplements.

To reduce the environmental impact of food, which applies to all food and not just meat, we need to accept the idea of not having excess of everything. We don’t need 5 different cuts of meat from 3 different brands. We don’t need 5 different kinds of apples. We don’t need a whole shopping isle filled with… Goodness knows how many different kinds of cereal.

Definitely agree with this, but its probably just as hard a sell, and much less feasible to do on an individual level.

No one is forcing them to live in a concrete prison.

Exactly.
