I'm not saying at all that it would be easy to get people to do what is in their best interest; though once they are properly educated, it would create a positive feedback loop. The more you exercise the more energy you have to exercise. The healthier you eat the less you have to spend on preventable diseases like heart disease and diabetes and so the more money you have to spend on healthy food. The solution to overpopulation, as evidenced by the Demographic-Economic Paradox, is clearly to raise the standard of living by successfully distributing the renewable surplus of food, water, and shelter that is available but wasted every year. This is also an example of turning a negative feedback loop into a positive feedback loop which in turn pays for itself. https://en.wikipedia.org/wiki/Demographic-economic_paradox https://en.wikipedia.org/wiki/Demographic-economic_paradox The issues of poverty, disease, and overpopulation are closely interrelated indeed.
