What to Focus On

  • Environment means all living and non-living natural things in a region.
  • Biotic elements are living components.
  • Abiotic elements are non-living components.
  • The three main environmental problems are pollution, degradation, and depletion of resources.
  • Pollution is an undesirable change in environmental quality.
  • A pollutant is the substance that causes pollution.
  • Air pollution affects breathing and heart health.
  • Carbon dioxide is an air pollutant and also a major greenhouse gas.
  • Human-made and natural sources both contribute to air pollution.

Common Mistakes to Avoid

Pollution, degradation, and depletion all mean the same thing.

Renewable resources can never run out, so they can be used carelessly.
