Plants are important to people because they:

provide oxygen to animals. are a source of food. provide fiber which is used for fabric. provide shelter, roofing, and building materials. produce by-products such as dyes, decorative bark. may be used to alter the local environment. produce medicinal chemicals.

  1. provide oxygen to animals. are a source of food. provide fiber which is used for fabric. provide shelter, roofing, and building materials. produce by-products such as dyes, decorative bark. may be used to alter the local environment. produce medicinal chemicals. Plants are important to people because they:

  2. Shade. Windbreaks. Erosion control. Noise control. Reduction of glare. Beautification. Production of nitrogen in legumes. Act as settling chambers for pollutants. Ways in which Plants Alter their Environments

  3. Shade • Reduces loss of soil moisture by cooling the soil. • Reduces local air temperature.

  4. Windbreaks • Reduce soil moisture loss by reducing evapo-transpiration. • Warm areas in cool weather by reducing the wind chill factor. • Prevent soil erosion.

  5. Erosion Control • Roots capture soil particles as they wash across the surface of the ground. • Leaves capture and slow rain water so soil particles are not so easily dislodged.

  6. Noise Control • Plants block sound waves from noisy streets, railroads, or buildings.

  7. Reduction of Glare • Plants absorb and soften sunlight. • Plants shade areas to reduce glare from sidewalks, streets, and buildings.

  8. Beautification • Plants help to make areas more attractive.

  9. Production of Nitrogen in the Soil • Soil micro-organisms coexist with legumes to make nitrogen for the host plant, as well as other nearby plants.

  10. Plants Act as Settling Chambers • Plants absorb particulate pollution (pollution which is in particles) and hold them within themselves .
