The benefits of parks enhance the local eco-system in many noticeable ways. Not only do trees and plants create necessary oxygen; they play a crucial role in retaining ground and rain water, and removing toxins from the environment. American Forests is an organization that studies municipal forests and the drawbacks of declining natural areas in cities. They educate by providing fascinating information like the fact that two trees can produce enough oxygen for one person and can absorb twenty pounds of carbon pollution every year. Parks also give shade, cooling down a large area and reducing heat retention. Air-conditioning requirements are reduced in a community with more canopy coverage. A car that is parked in the shade stays fifty degrees cooler than one parked under the sun. In urban locales, natural spaces must be developed and maintained through human intervention and assistance, notes Marcus Hiles.
The advantage of city wildernesses improves the resident eco-system in countless helpful ways. Apart from trees and plants providing oxygen, they also help prevent rain water from flooding the residential areas and help purify the air. The organization American Forests conducts researches on how the damages in forests affect the cities badly. Beside researching, they also provide the people information of the 2:1 ration of trees to a person in terms of giving off and using of oxygen, and also how 20 pounds of air is purified by these trees every year. Community parks help give shade and lower heat in hot places. Those who live in locations where trees are bounty find that air-conditioning is needed less. There is a decrease of fifty degrees in the temperature of a car if it is parked in the shade compared to one that is now. Public spaces in bigger cities even build manmade parks and maintain them regularly.
