Global Warming: The Effects on Forestry and Agriculture
Forests are an important use of land in most countries. This is true for many reasons, but when it comes to global warming, it is particularly true. Plant life can scrub carbon dioxide from the air. Much of the very carbon dioxide that is one of the causes of global warming can be eliminated just by being in the vicinity of certain plants.
One law was proposed to stop logging and road building in the forest to prevent global warming. This particular law was to protect a large amount of forest-approximately 13 million acres on ancient forest. Most of this forest was so unspoiled that it did not even have any roads at all. This law would also ban clear-cutting, a practice that totally destroys acres upon acres of old growth trees.
As if this was not enough, greenhouse gases have increased by deforestation. These gases include methane and nitrous oxide. Global warming is foreseeable when people greedily take the rainforest and other forests for their own purposes.
How agriculture is affected by global warming
Because of global warming, temperatures obviously increase. This has some temporary benefits. For awhile, it will simply mean more time for crops to mature because of a longer growing season. This is especially true of regions where the spring and fall were once quite cool.
Strangely enough, all the extra carbon dioxide in the air that brings about global warming also has a fertilizing affect on crops. This type of fertilization is most helpful for crops such as wheat, soybeans, and rice. CO2 fertilization is a beneficial by-product to global warming.
However, this benefit may all be in vain. When global warming pushes ground level ozone to higher stages, the carbon dioxide fertilization is voided out by troposphere ozone. These ozone levels are influenced by both emissions and temperature. The result is that when the climate changes, the ground ozone levels will rise as well.
Global warming is responsible for many climate changes. Often, people cause the increase in global warming that precipitates these changes. If people could make it a common goal to cut down on activities that promote global warming, the earth would be a much more stable environment.
