Solutions that are not "acceptable enough" are not solutions, they are notions.

We can still "have it all" -- flight, meat, etc., if the right incentives exist; this too is more notion than solution but is the only possible path.

We can make "sustainable" fuel, and cattle can be fed seaweed and restricted to existing range lands (i.e., don't destroy more forests).

A key problem is that this issue and associated solutions have been artfully politicized by their incumbent stakeholders so a significant portion of the population will resist these efforts purely out of spite.
