Thats whats happening now.
To some extent, it is happening now.
But, in the coming future, it will probably happen in a much, much bigger way, than now.
E.g. Very few people actually drive 100% electric vehicles.
But in coming decades, that is likely to change, dramatically.
Banning of new cars being Petrol/Gasoline/Diesel, seems to have already been announced, in some areas of the world.
I'm NOT looking forward to the proposed replacements of meat.
Such as INSECTS.
For example, this very recent news story, about eating them.
I would feel sick, just reading the article and/or its pictures, video if applicable.

tl;dr
There is NO way in a million years, that I will be going to that supermarket and trying the "tasty" insects.
(I'm being serious).
