World population is rising, but most prosperous countries have falling birth rates and are either shrinking, or barely kept from shrinking by immigration. This is a problem. It means many more people are born into poverty and a life where they will barely scrape by, whilst the people with any kind of access to effective production get fewer, and spend more time taking care of dependents than on improving the lives of others. We don't just need to drop birth rates in poor countries (by reducing child mortality, and increasing prosperity). We also need to increase birth rates in the prosperous countries.
