Advantages of Trees

Environmental Benefits of Trees

  • Half a hectare of trees produce enough oxygen for 18 people every day and keeps pollutants in check.
  • Trees absorb and deflect sunlight which cools the air and alters rainfall patterns.
  • Trees act as natural water filters and help reduce runoff, soil erosion and flooding.
  • Trees absorb sound waves, reducing noise pollution.
  • Trees create natural environments which attract and provide habitats for birds and other wildlife.

Economic Benefits of Urban Trees

  • Trees planted around a home reduce cooling and heating costs by as much as 30 percent.
  • Healthy trees can add up to 15 percent to residential property values.
  • Greenspace encourages outdoor activity

Health Benefits of Urban Trees
