Trees remove pollutants from the air.

Poor air quality is a common problem in many urban areas. It can lead to health problems, landscape damage, degraded ecosystems, and reduced visibility.

  • Carbon monoxide (CO) interferes with oxygen delivery within the human body.
  • Nitrogen dioxide (NO2) contributes to ozone and fine particle pollution and is linked to adverse respiratory system effects.
  • Ozone (O3) is harmful near the ground and can worsen lung diseases such as asthma, particularly in children.
  • Particulate matter (PM), or particle pollution, is a complex mixture of extremely small particles and liquid droplets that can cause serious health effects.
  • Sulfur Dioxide (SO2) can make breathing difficult. It contributes to acid rain and can react with other compounds in the atmosphere to form visibility-reducing haze.

Trees absorb carbon dioxide from the air and store it as wood.

Carbon dioxide (CO2) is a greenhouse gas that traps heat in the atmosphere.

  • It enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and wood products, and also as a result of certain chemical reactions (e.g., manufacture of cement).

In addition, your trees:

  • Enhance property values
  • Improve health and well-being
  • Reduce storm water runoff
  • Lower summer air temperatures
  • Provide wildlife habitat
  • Provide aesthetic benefits
