The size of the human population, in the near-term and distant future, is a key determinant of climate policy: All else equal, a larger population entails more emissions and therefore more mitigation to achieve a given climate target (13), and it also means more future people will be vulnerable to climate-related impacts.The extensive time lag between the With more people living on the Earth, more houses are being built and animal habitats are being destroyed. The carrying capacity varies annually. Coastal population growth exerts strong pressure on coastal land by increasing the need for both agriculture and housing, and land-use demands often come at the expense of natural habitats and native species.Agriculture reduces biodiversity by replacing native communities with monospecific crops, and urbanisation causes direct habitat loss.
