Trees store carbon dioxide. When they get cut down they realease this gas. It contributes to greenhouse gases. now that there is so much carbon dioxide in the atmosphere they are letting it offeven if they are not cut down. also scientists have found that over rainforests that clouds are forming higher letting little rain reaching rainforests drying them up. soon they will all be gone! The answer above is very, very wrong. Yes, trees store carbon dioxide. However, when they are cut, this carbon dioxide is not released. On the contrary, it is permanently [b]sequestered[/b] in the wood and wood products made from that tree. (Next time, do some research before you delete information provided by someone who knows what he is talking about.) On the other hand, if we didn't cut them down, then they would eventually die. And when the die, they will rot. And When they rot, they will release that carbon dioxide. Moreover, once they are cut, if the acreage is replanted with seedlings, those seedlings will grow much faster, and store more carbon dioxide per year, than the older trees that were cut down. The one thing that should be avoided, however, is burning trees. Like rotting, this releases carbon dioxide into the atmosphere, only very suddenly, rather than gradually as with rotting.
Deforestation is a contributor to global warming, and is often cited as one of the major causes of the enhanced greenhouse effect. Tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions
Yes, deforestation increases the greenhouse effect because trees absorb carbon dioxide (a greenhouse gas) from the atmosphere. When trees are cut down or burned, this stored carbon is released back into the atmosphere, contributing to global warming and climate change.
Yes. When we started burning fossil fuels (coal, oil and natural gas) and cutting down the great forests of the worldd (deforestation), the normal greenhouse effect began to change into the accelerated, or enhanced greenhouse effect which we now have.
Trees remove carbon dioxide (CO2), a greenhouse gas, from the atmosphere and store the carbon in their trunks and branches. When deforestation happens and the trees are burnt or rot, that carbon dioxide is added to the atmosphere, and because no more trees are planted, there is no longer anything to remove the CO2. This is how deforestation adds to the greenhouse effect.
The natural greenhouse effect keeps the earth warm enough for life.The enhanced (or accelerated) greenhouse effect (caused by burning fossil fuels and deforestation) leads to global warming and climate change.(There is also the very dangerous runaway greenhouse effect that happened on Venus.)
Forests and all vegetation remove carbon dioxide from the greenhouse gases in the atmosphere. Deforestation, cutting them down, means that the greenhouse effect is increasing. This is causing global warming and climate change.
Deforestation and the burning of fossil fuels (coal, oil and natural gas).
Deforestation of the rainforests destroyed trees that used to remove carbon dioxide (CO2) from the atmosphere. This allows CO2 levels to build up in the atmosphere. Greenhouse gases cause the greenhouse effect, keeping the earth warm. Because of deforestation and man's burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, levels of CO2 in the air are rising, causing global warming.
Increased emission of greenhouse gases such as carbon dioxide and methane from human activities like burning fossil fuels and deforestation.
The natural greenhouse effect keeps the earth warm enough for life.The enhanced (or accelerated) greenhouse effect (caused by burning fossil fuels and deforestation) leads to global warming and climate change.(There is also the very dangerous runaway greenhouse effect that happened on Venus.)
Combustion (burning) of any material usually releases carbon dioxide, as carbon is such a major component of everything on earth. Deforestation (removal of trees) means that the trees are no longer able to take carbon dioxide from the atmosphere. The greenhouse effect is the greenhouse gases retaining warmth from the sun. Any increase of greenhouse gases (as carbon dioxide is) leads to a warming in the atmosphere.
The enhanced greenhouse effect,which is caused by extra amounts of greenhouse gases like carbon dioxide,which is caused by burning fossil fuels and deforestation.
