Solution
The effect of chopping down a forest can be all of the above, depending on what happens to the trees after they are cut down.
-
Emitting carbon dioxide because the forests should never be chopped down: This statement is more of an opinion than a fact. However, it is true that forests play a crucial role in absorbing carbon dioxide from the atmosphere, which helps to mitigate climate change. When forests are chopped down, this important function is lost.
-
Emitting carbon dioxide if the wood is burned or decomposes: This is true. When wood is burned, it releases the carbon it has stored during its lifetime back into the atmosphere as carbon dioxide. Similarly, when wood decomposes, it is broken down by bacteria and other organisms, a process that also releases carbon dioxide.
-
Removing carbon dioxide because the tree absorbs carbon dioxide: This is also true, but only while the tree is alive and growing. Trees absorb carbon dioxide from the atmosphere during photosynthesis, a process in which they convert carbon dioxide and sunlight into oxygen and glucose. This is why forests are often referred to as "carbon sinks". However, once the tree is cut down, it can no longer perform this function. If the wood is not used in a way that keeps the carbon it has stored sequestered, such as in long-lasting wood products, the carbon will eventually be released back into the atmosphere.
Similar Questions
Over the past 200 years, people have been cutting down forests all over the world at a very fast rate. This has added large amounts of carbon dioxide to our atmosphere. Part of the reason is that when trees are burned, they release carbon dioxide. Why else would cutting down trees increase the amount of carbon dioxide in the atmosphere? A. Trees make carbon dioxide through photosynthesis. B. Trees, like all plants, use up carbon dioxide. C. Trees provide shelter for other living things that produce carbon dioxide. D. Trees give shade, which cools Earth's surface.
In some parts of the world, rain forests are being cut down to make land available for new homes. How does the loss of these trees impact the carbon cycle?*1 pointThe trees will no longer be able to undergo photosynthesis which will decrease the amount of oxygen within the atmosphereThe trees will no longer be able to undergo photosynthesis which will decrease the amount of carbon removed from the atmosphereThe trees will no longer be able to undergo respiration which will cause the amount of carbon within the atmosphere to be removed.The trees will no longer be able to undergo respiration which will decrease the amount of fossil fuels produced.
