air pollution

• There are many reasons for growth in population:

  • Improved technology leading to an abundance of food = rapid increase in birth rate
  • Improved medicine, hygiene and health care = decrease in death rate
  • Rapid growth in the human population and an increase in the standard of living means our negative effect on the environment is also increasing
  • As increasingly more resources are used to sustain the growing human population, more waste is produced and more pollution is created
  • Unless waste and chemical materials are properly handled, pollution will continue to be created
