What to Focus On

  • Environmental degradation is caused by pollution, deforestation, and overuse of resources.
  • Ecosystems become weaker when human activities disturb natural balance.
  • Forests are important for climate regulation, soil conservation, and water cycles.
  • Deforestation is the large-scale removal of forests.
  • Habitat loss occurs when natural living spaces are destroyed or altered.
  • Biodiversity loss reduces ecosystem stability and resilience.
  • Air pollution harms both human health and the environment.
  • Main air pollutants include carbon monoxide, nitrogen oxides, sulphur dioxide, and particulate matter.
  • Sources include vehicles, industries, fossil fuels, and some natural events.

Common Mistakes to Avoid

Unsustainable development only harms nature, not people or the economy.

Deforestation means any use of forest land, so planting crops or building roads inside a forest is not a problem.

Habitat loss and biodiversity loss mean the same thing as extinction.
