Asian and African cuisine are far less reliant on meat (as a percent of their diet) to bring flavor to their food. However, I rarely see vegans driving adoption for Indian/Haitian/west-african food. Instead it is the same old efforts towards mastering the vegan beef patty/sausage and vegan pizza. Guess what, India has had an amazing mc Aloo Tikki & mcVeggie in McDonald's for 20 years and they taste better than any vegan burger that is readily available. Let alone native dishes that are far more aligned with vegan ingredients.
As long as our diets are reliant on meat and dairy as the sources of flavor and lynchpins of the cuisines, we won't see a perceptible change in net contributions to environmental degradation and climate change.
At the same time, the recycle campaigns of the 2000s have shown that expecting ground up action from the customer almost never works. There needs to be a production side once give to push sustainable solutions. Maybe we could start with. Ew balancing subsidies to push sustainable practises in the food industry. But food luck getting past that lobby.
