I do believe that charitable efforts have the responsibility to mitigate the risk of a demographic trap in the areas they serve. But I think getting anybody who matters to listen is a lost cause.

The Bill and Melinda Gates foundation accounts for a good share of charity spending. They started by being very focused on the issue of reducing population.

They spent millions on the issue and have seen the empiric effects of their projects. To the extend that they don't listen anymore to the kind of arguments that you are making is that they updated in face of empiric evidence.
