The life and value of a park
Developers an other interests often denigrate the value and purpose of our parks and green space in order to commercialise public space. When somebody tells you “Nobody uses it” “The parks have to pay for themselves” along with the sometimes pathetic excuses used to allow building on green space by developers and city administrators alike. Give them a cost benefit analysis on our green space. How do parks more than pay for themselves by:
Detoxing the environment.
The production of oxygen.
The removal of carbon dioxide and other toxins.
Creates water drainage and anti-flooding.
Wild life habitats.
Benefits for mental health.
The vistas and sense of space as a release from manic traffic.
A space to exist as a family unit. Reduces friction, stress and family
Escape from city stress that leads to crime and violence.
Building block for a sense of community
Autonomous space equality for everybody.
Safe for bikes, safe for football, amateur sports, productions, events, physical space.
Freedom of speech Speakers Corner. Tradition of protest, Rally's.
Last bastion of space for the poorest in our communities.
The countryside in the city
An excellent recipe for childhood education
Stagnant ponds could be rejuvenated by solar power fountains. And introducing the person on the street to science.
The park belongs to no one and to everyone
Look at just one element of our parks, trees.
Evergreen trees can be used to reduce wind speed (and usefully loss of heat from your home in the winter by as much as 10 to 50 percent.) Trees absorb and block noise and reduce glare. A well placed tree can reduce noise by as much as 40 percent.
Fallen tree leaves can reduce soil temperature and soil moisture loss. Decaying leaves promote soil microorganism and provide nutrients for tree growth.
Trees help settle out and trap dust, pollen and smoke from the air. The dust level in the air can be as much as 75 percent lower on the sheltered side of the tree compared to the windward side.
Trees create an ecosystem to provide habitat and food for birds and other animals.
Trees absorb carbon dioxide and potentially harmful gasses, such as sulphur dioxide, carbon monoxide, from the air and release oxygen. One large tree can supply a day's supply of oxygen for four people. A healthy tree can store 13 pounds of carbon each year - for an acre of trees that equals to 2.6 tons of carbon dioxide.
Each gallon of petrol burned produces almost 20 pounds of carbon dioxide.
For every 10,000 miles you drive, it takes 7 trees to remove the amount of carbon dioxide produce if your car gets 40 miles per gallon (mpg); it will take 10 trees at 30 mpg; 15 trees at 20 mpg; 20 trees at 15 mpg; and 25 trees at 12 mpg)
Trees help reduce surface water runoff from storms, thus decreasing soil erosion and the accumulation of sediments in streams. They increase ground water recharge and reduce the number of potentially harmful chemicals transported to our streams.
An acre of trees absorb enough carbon dioxide in a year to equal the amount produced when you drive a car 26,000 miles.
That's just trees.
