Hi..I LOVE GREEN ENVIRONMENT:
Under the effect of solar radiation, trees will absorb water from the soil, heat-absorbing solar radiation and absorb carbon dioxide from the air to conduct continental shale and release gas Chemical Oxygen - very useful for health human health and reducing air "greenhouse". So considering not planting trees on unused land, the air temperature in the lower daytime trees from 1-30C, oxygen content in the atmosphere is greater than 20% and less CO2. During continent of green chlorophyll absorbs solar radiation, absorbs the heat should have the effect of reducing the harshness of hot days, reduced reflection of solar radiation on the building, reducing the temperature does not Gas under the trees and can increase air humidity from 2% - 5%, increase air humidity is also beneficial for hot dry day.
Average 1 adult per day 0,75kg O2 respiration and 0.9 kg of CO2 emissions. Therefore each urban residents should have an area of about 10m2 or 25 m2 green lawns to ensure good air quality for human life.
-Trees capable of storing rain water on the plant part, keep the spongy ground with tree roots penetrate the ground to help rainwater penetrates quickly into the ground, reducing flooding situation in the municipality. It is through this feature that in the midlands and mountainous, forest green harmonic effects of rainwater, reducing soil erosion, reduce flood overflow, flooding, flash flood.
- Trees absorb potentially harmful contaminants in water and in soil, especially to absorb and hold permanent storage of heavy metals, such as lead, arsenic, mercury .. . in the tissues of green packaging, in the trunk, branches and roots of trees capable Due absorb pollutants, so now they have used a number of plant species in line processing system sewage, and is studying to use some plants to treat contaminated soil, absorb heavy metals, soil quality restoration, including the absorption of dioxin in the soil.
