How increasing population is exerting extra pressure on land and mineral resource discuss.
- The total human population has expanded since the introduction of agriculture, around 12,000 years ago, and its rate of growth has generally increased over time
- The increase in in population growth rate is largely as a result of increased food production, improved sanitation and health care.
- Achieving the first one billion of human population took most of human history, whilst the most recent increase of one billion was achieved in little more than a decade.
- However, recent declines in the rate of growth of population have occurred in many parts of the world, and in some countries populations are now declining.
- The United Nations projects that the world’s population will be anywhere between 7.7 billion to 11.2 billion by 2050, that's an average of 9.5 billion by that time.
- Human population growth and overconsumption are at the root of our most pressing environmental issues like depletion of resources, environmental pollution, species extinction crisis, habitat loss and climate change.
- Significant differences exist in cultural attitudes to the issues of human population size and the rate of population growth.
