Addressing the concerns that no solutions are offered and that population reduction is not discussed: Talking about slowing the population growth rate is in fact about reducing population number over the long term. If you do a statistical analysis of human biological communities, the most effect way to reduce the population is to delay the average age of reproduction by 5-10 years. It beats immigration restrictions, sterilization and reducing the number of children every person procreates. And the best way to delay the reproductive age is by increasing the number of young people, women especially in schools.
This is partly what Dr. Sachs is getting at when talking about the large potential impacts of education programs and other social projects to address shortfalls in water, food and jobs. In the long term, increasing education also increases technological innovation, which will also help alleviate these shortages.
