There are things that people are not willing to pay for, and government types have labelled these things "market failures", which, BTW, is a misuse of the term.
Government has then stepped in and run programs that people are not willing to pay for.
So the question really boils down to "how would you make something that noone has ever figured out how to make profitable...profitable?"
It's a bit like recycling: there have been metal recyclers for centuries. People do not recycle glass and paper because it is a value DESTROYING activity.... and thus government got involved, and requires people to separate their trash streams...before recombining about 75% of the "recycled" materials and putting them in landfills.
The only good answer to this question is "mu".
