  • Soil been gradually worn away by natural phenomena (rivers, rain, waves)
  • Human activities (Clearing trees)

    • caused by a chemical change

    Soil can degrade by:
    • becoming compact
    • large machinery 
    • hard-hoover animals
    • becoming acidic -> buildup of fertilizer/loss of soil nutrients due to over farming

  • Air pollution is one of the worst health risks today
  • leads to an increase in asthma, lung & heart disease
  • 3.5 million people die each year from outdoor air pollution - High concentrations of fine particles in the air from factories, traffic exhaust, factory and power plant emissions, and fires 
  • 4.3 million people die each year from indoor air pollution - coal and dried animal waste burn indoors for heat & cooking (mainly in developing countries)

  • the natural ecosystem of an area (Forest & stream) can become degraded
  • Maybe through invasion of alien plants & animals, loss of vegetation, or decline in the quality of streams and rivers
