This document discusses several issues related to human population growth and its impact on the environment. It notes that the global population will likely exceed 7 billion by 2015 and meeting the needs of this many people will be difficult without degrading natural resources and environmental quality. Rapid population growth in recent decades has contributed significantly to environmental problems. Other issues discussed include variations in population growth rates among countries, links between poverty, health and the environment, climate change impacts on health, and the importance of equitable distribution of resources.
