Green plants aren't just important to the human environment, they form the idea for the sustainability and long-term health of environmental systems. Green plants remove CO2 from the atmosphere and generate the oxygen required for all times . Green plants also are an honest source of food and protection.

Photosynthesis
Photosynthesis is that the process that green plants use to convert light into energy , within the sort of energy-rich sugars, required for growth. The green color plants results from a chemical referred to as chlorophyll. Chlorophyll absorbs the blue and red portions of the sunshine spectrum but reflects green light, making most plants appear green. Photosynthesis consumes CO2 as a part of the photosynthetic process, emitting oxygen as a byproduct.

Oxygen
An important byproduct of photosynthesis is oxygen. consistent with the North Carolina State University, one large tree can produce enough oxygen for four people in at some point .

Carbon Dioxide
Plants use CO2 while photosynthesizing, removing it from the atmosphere. the planet Bank estimates that 20 percent of accelerating atmospheric CO2 levels has resulted from deforestation. They estimate that the maximum amount as 50 percent of worldwide warming over the past 50 years is thanks to changing land use patterns and deforestation within the modern age. one tree is estimated to soak up 1.33 plenty of CO2 per 100 years, a mean of just over 26 pounds of CO2 per annum .

Natural Cooling and Soil Stabilization
Green plants provide natural cooling. Leaves block the heating effect of the sun. Green plants also can cool through transpiration, although without large numbers of trees and other plants this effect is minimal. Transpiration is that the process by which water evaporates from plant pores, cooling the environment via evaporative cooling. Evaporation consumes heat and is best for cooling when the humidity is low. Plants also stabilize the soil through their roots, which bind soils, and thru their leaves, which keep raindrops from eroding soils. Areas without adequate vegetative cover often suffer from large quantities of sediment washing into streams and lakes, diminishing water quality.
