It's not simple. Trees both help and hurt.

Trees take CO2 from the air and use it to make wood and grow.

But, at night, they breath like we do, taking in oxygen and releasing CO2. The also release CO2 when they die. They're relatively dark and can absorb sunlight and warm.

Roughly it goes like this. Tropical rainforests are valuable in fighting against global warming. Days are longer than nights. Trees grow rapidly there, making a lot of CO2 into wood. When they die, other plants use the decaying trees for growth.

Nearer the poles, where there's a lot of snow, trees can hurt by replacing reflecting snow with dark trees. They grow slowly there, and the growth doesn't make up for the color.

In between, trees help, IF you harvest the wood and don't let dead trees decay.

Yes, if everyone on this planet planted 3 trees, global warming could be prevented. If you take into account that not everyone can plant trees (some are too young, disabled, poor, ignorant, etc.) Then if each person able to plant trees could plant 9 -11 trees, then global warming could be prevented. But- if you realize that not every planted tree will actually grow (human error, natural problems, etc.) then if every person able to could plant 20 -30 trees, I am sure that global warming could be prevented. Even better, if everyone who could do it, planted 75 trees, that would bring on another Ice Age. Seriously, Al Gore said it recently, and he was serious. This Ice Age would also reverse the geological processes that pose bigger threats than global warming ever will. Volcanoes are going to begin erupting, wiping the planet clean of us parasitic humans. (Yellowstone is due to erupt any day now, give or take a few thousand years.) In the time you wasted reading this, you could have planted a tree or two.

Like humans, trees have a breathing mechanism. We breath in air and utilise the oxygen in it, when we breathe out we exhale less oxygen and more carbon dioixide (CO2) than when we breathed it.

Trees do the opposite, they breathe in CO2 and exhale oxygen, it's part of the process by which trees and other plants grow - photosynthesis.

CO2 is a greenhouse gas, the more of it there is in the atmosphere the more the planet warms up. When trees absorb CO2 they're preventing it from entering the atmosphere and so are helping to slow down the effects of global warming.

There are other more complicated ways in which trees help slow global warming but this is the most important one.

hmmm... Global Warming is caused by the fumes of the factories,of the cars, of the airplanes and of many other things. The main Fume is the CO2(Carbon dioxide), which doesn't allow the heat of the sun return to space. Anyway, Trees produce oxygen and absorb CO2, so if we plant trees we reduce the rates of carbon dioxide in the air and by that way we can confront the problem of Glabal Warming

Trees are composed of carbon, hydrogen and some other minerals, as all other plants. They absorb the carbon from CO2 and covert it into CH compounds, using Solar energy and water. By emitting O2 into the atmosphere as byproduct of this process, they reduce the Green House effect to certain degree, and this degree is "chain effected."

The "total mass" of trees depends on much greater climatic factors, but humans have destroyed 50% of them in the last century. Europe 60%, with Spain alone having destroyed 90% of their trees... Even if humans plant new trees, these new trees are less resistant due to the destroyed ecosystem; flora and fauna the trees were part of.

Trees are not only important because of the Global Warming. They are an important part in the ecological system; in the chain of interdependent lifeforms which depend on plants for their survival, among whom are humans, as much as "some humans (read: human lifeforms) think differently."

In other words, trees absorb life energy the Sun gives, and we the humans absorb it from the trees. Humans are not capable to live only out of CO2, H2O and Heat (thermal or solar.)

Trees destroyed, alone are just one factor in the Global Warming, rather are a reflection of the "human nature," along with the crippled ozone layer, chemical and radioactive pollution, depletion of species, etc. The biggest problem is petroleum consumption. "Realists" (as some people here call themselves) argue if humans influence the Global Warming at all, due to Cosmic and God factors. These people destroy rainforests, create monocultures and live out of surplus of money and power in deciding the fate of all of us.

They think locally, but act globally.

Bastards.

Cars produce energy by combustion, in which you need hydrocarbon (gas) and oxygen to produce carbondioxide and water. An average American car produces 12000 pounds of co2, and you would need 240 trees to absorb that co2. simple. Trees absorb carbon dioxide from atmosphere.

well we really don't need trees to breathe, 80% of our oxygen comes from underwater plants. We need trees, to clean are our air, they absorb dust particles as well as other things like c02 emissions from cars to your local power plant.

Absorb the carbon dioxide in the air.

Not much, phytoplankton in the oceans do most of the work, but trees can look nice.
