The Environmental Value of a Garden
Forest trees absorb Co2
We know trees are the lungs of the world but a fast-growing forest tree will absorb up to 48 pounds of Co2 over a single year; approximately ten tons per acre of forestry – that is enough to offset the Co2 output produced by driving a car 33796 kilometres. The equatorial circumference of the earth is 40075km.
Garden trees do their bit
It is not just forests, over a single living year a mature garden tree will also absorb carbon dioxide at a rate of 48 lbs per annum and in the process will replenish the atmosphere with enough oxygen to support 2 human beings.
Filter your air
On a busy road a single Sugar Maple (Acer saccharum) will remove 5200mg of lead, 60mg of cadmium, 140mg of chromium and 820mg of nickel from the environment in a single growing season. While our native Whitebeam (Sorbus aria) is one of the best trees at removing harmful particulates from the atmosphere.
Even a patch of grass makes a difference
Even a simple lawn provides fresh air: A 2.4 square meter patch of grass will daily convert enough carbon dioxide to supply the oxygen requirement of one person per day. And every garden plant is a bio-filtration system for the planet. They produce almost all of the oxygen content in the air we breathe. Remember too that Houseplants do for indoor air what garden plants do for the exterior atmosphere.
Reduce greenhouse gases
Plants Help modulate greenhouse gases via transpiration and other processes. By growing plants and trees on top of a landfill, a process known as 'Phytocapping', seriously reduces the production and release of methane and carbon gases.
Plants purify water
They clean run off water that enters the water table and they can be utilized in reed bed systems to filter grey water for reuse around the home and even to recycle water for consumption.
Plants reduce flooding and water run-off
Plants can prevent floods, droughts, and soil erosion and in ecopyschology and practical regeneration they help repair the landscape after natural and human disasters.
Provide important wildlife habitats
Plants feed us, medicate us, produce fuel, fabric and useful artefacts but are just as valuable in their creation of natural habitats and preservation of biodiversity. Wild and manicured urban gardens maintain biodiversity in cities and towns.
