Whilst our day-to-day lives are seemingly unaffected by population growth, the impact over our lifetime and beyond is significant. Each year the world’s population grows by approximately 83 million people, yet the capacity of our environment is finite. Population issues such as growth, ageing, migration and urbanisation majorly affect:

  • Water supplies and usage
  • Land use and food production
  • Energy sources and management
  • Urban planning and development
  • Health and welfare systems
  • C02 emissions

World Population Day, 11 July, focuses attention on the urgency and importance of understanding and addressing these population issues. Past and projected impacts of population growth on food and agriculture, health, society and the environment can be viewed with the World Population History interactive map.
