Kelvin Thomson discusses immigration and population growth's global impact on rising food prices, increased demand for grain and petroleum, and population's direct impact on social unrest. Recent findings demonstrate how rapid population growth fuels political instability. Thomson discusses the situation in countries such as Tunisia, Nigeria, Kenya, and Ghana, where too many people competing for scarce available resources ultimately lead to social conflict. In many developed countries, high immigration has lead to higher unemployment rates and civil unrest. Thomson explains how policy makers should focus on policies to slow migration to solve social problems.
