forests are like the lungs of the Earth — inhaling carbon dioxide and exhaling oxygen that we all need to survive. Destroying forests releases more carbon dioxide into the atmosphere each year than all of the planes, trains, cars, trucks and ships — combined. People all over the world — from rural communities to the biggest cities — are affected by global deforestation. Your support will go toward helping Conservation International protect the places where we can make the greatest impact, putting good conservation practices in place for the long term.We call it the environment, but that's the wrong word. It's our extended body. We have a “personal body” and a “universal body”, and they're both equally ours. When we have that experience, that knowledge, it will become impossible for us tooo hurt the earth. So my friends, don't choose the word 'environment"; look at the earth as your mother from where you were born, and also remember that all its beautiful forests, its flowers and gardens, its trees, its atmosphere, its rivers -- they're all a part of our own biological organism. Love her... as you love yourself.

We return thanks to our mother, the earth,
which sustains us.
We return thanks to the rivers and streams,
which supply us with water.
We return thanks to all herbs,
which furnish medicines for the cure of our diseases.
We return thanks to the moon and stars,
which have given to us their light when the sun was gone.
We return thanks to the sun,
that has looked upon the earth with a beneficent eye.
Lastly, we return thanks to the Great Spirit,
in Whom is embodied all goodness,
and Who directs all things for the good of Her children
It will cost 38 trillion dollars to create oxygen for 6 months for all human beings on Earth" TREES DO IT FOR FREE"SAVE THEM ♥
When we are willing to make peace within ourselves, and peace with the environment in which we live and peace with each other and the animals we love and peace with the world so there are no wars, we will begin to understand how blessed we humans really are while we're on this earth and among each other and the more we strive for this Peace on Earth the more we will leave Paradise behind for those that come after us. ♥
But indeed, it is not so much for its beauty - that the forest makes a claim upon our hearts, as for that subtle something, that quality of the air, that emanates from the old trees, that so wonderfully changes and renews a weary spirit ♥
The sounds of birds chirping announces the rising of the sun and the coming of a new day. Each morning is a time for a fresh start and a new and wonderful beginning. We should never forget the sacrifices others have made for us and to honor them we should live our lives to the fullest ♥
Forests, lakes, and rivers, clouds and winds, stars and flowers, stupendous glaciers and crystal snowflakes - every form of animate or inanimate existence, leaves its impress upon the soul of human ♥
One who neglects or disregards the existence of earth, water, fire, air,vegetation and all other lives disregards his own existence which is entwined with them ♥
Trees do not hate. Though man delights in destroying plant life, I have never known plants to let down man ♥
The Great Spirit is in all things: he is in the air we breathe. The Great Spirit is our Father, but the earth is our mother. She nourishes us; that which we put into the ground she returns to us.♥
Earth and sky, woods and fields, lakes and rivers, the mountain and the sea, are excellent schoolmasters, and teach some of us more than we can ever learn from books ♥
The human spirit needs place where nature has not been rearranged by the hands of human ♥
We have poisoned the air, the water, and the land. In our passion to control nature, things have gone out of control. Progress from now on has to mean something different. We’re running out of resources and we are running out of time ♥
Air pollution is a serious problem in the United States. As a young child growing up in suburban Los Angeles, I remember days in which we were not allowed to play outside because of the air quality. Kids in other states had snow days, or so I was led to believe, but we had smog days.
LA is doing better now. We don’t have smog days anymore. But air pollution still causes quite a bit of problems, both for public health as well as for the cost of health care. It’s been implicated in diseases like bronchitis, asthma, and other respiratory conditions. It impacts the cardiac, vascular, and even neurological systems. It leads to emergency room visits, hospital admissions, and sometimes mortality. Kids miss school, adults miss work. Thankfully, we have trees. It is not an exaggeration to say that trees save both lives and money. That’s because they scrub the air of pollution.
The Clean Air Act required the U.S. Environmental Protection Agency to set air quality standards for six “criteria pollutants” that are both common throughout the country and detrimental to human health and welfare: carbon monoxide, nitrogen dioxide, ozone, lead, sulfur dioxide, and particular matter, which includes tiny little bits of stuff less than 2.5 microns in diameter. In 2005, particulate matter was implicated in some 130,000 deaths, and 4700 were related to ozone.
But the truth is, those numbers could have been much worse if not for the trees. That’s according to a new study by U.S. Forest Service researcher David J. Nowak and colleagues, published this week in the journal Environmental Pollution.
Trees remove air pollution in two ways. Some pollutants get stuck to the plant surface itself. That’s just a temporary removal, as wind can shake the pollutants back into the air, and rain can wash it down into the soil. The primary way in which trees remove pollution is by sucking up the gases through tiny openings on leaves called stomata, which literally means “mouths.” That’s especially true for ozone, sulfur dioxide, and nitrogen dioxide.
In the current study, Nowak’s team set out to determine what the health impacts and economic benefits are of air pollution removal by trees in the continental United States. Using public records available for 2010, the researchers determined that trees and forests removed more than 17 million metric tons of pollution from the air that year. In terms of saved health care expenses, that is associated with a value of $6.8 billion dollars.
Estimated removal of air pollutants for each US county in 2010.
More than 96% of pollution removal due to trees occurred on rural land, simply because most of the United States is classified as rural. However, the health effects were more heavily weighted in urban areas – more than 68% – simply because more people live in cities. Therefore, Novak concludes, “in terms of impacts on human health, trees in urban areas are substantially more important than rural trees due to their proximity to people. The greatest monetary values are derived in areas with the greatest population density,” like Manhattan.
It’s worth pointing out that the reason that cities are weighted so heavily is that Novak’s analysis reflected the EPA’s “primary quality standards,” which are aimed at human health. If he also considered the EPA’s secondary standards, which describe protections for animals, crops, vegetation, and buildings, then the relative value of rural trees would certainly increase.
Taken together, the pattern is very straightforward: “the greater the tree cover, the greater the pollution removal; and the greater the removal and population density, the greater the value.” Of course, trees also benefit human welfare in other ways. They reduce air temperatures, for example, which can in turn reduce the need for air conditioning.
And here’s the kicker: the 17 million tons of pollution removed by trees, and the associated $6.8 billion dollars saved, represents less than one percent of the pollution swirling around our air. Imagine how much healthier and richer we could all be if we simply planted more trees in our cities. – Jason G. Goldman | 01 August 2014
