Counter argument. More developed nations, such as countries in Europe, Japan, and The United States either have a stable or declining population growth. The only reason half those countries, such as the US, has a growing population is because of immigration. There's a direct correlation between the number of children a woman has, her job, her income, her education level, and the country she lives in. Furthermore, every decade, every year, every month, we're coming up with more and more techniques in engineering, agriculture, and medicine to take care of the people we do have. Equilibrium is possible. Hell, if it'll really help, bringing down the total global population without resorting to anything drastic or ugly is possible. We just need to focus on programs to achieve those means. You know, ones focused on what I just listed.
