Forestry and Global Warming: How Can Our Forests Effect Climate Change?
Mike Hirn asked:
The amount of land dedicated to forests, particularly old growth forests, could significantly reduce global warming. Forests are an important use of land in most countries, and in modern times they take on a new, environmental significance. Plant life scrubs carbon dioxide from the air. Carbon dioxide is a main cause of global warming and can be eliminated just by being in the vicinity of certain plants.
Trees are the best carbon dioxide scrubbers found in nature. Old growth trees are especially good at removing carbon dioxide from the air and storing it within their cells. For this reason, old growth trees need to be preserved. The lumber trade argues that the old growth trees can be easily replaced by new trees, but this is simply not the case. New trees do not possess the abilities that old trees have of preventing global warming by trapping carbon dioxide. Some proponents of cutting suggest that certain new trees are capable of trapping more greenhouse gases than the old trees. This is not true when you compare the new special trees to trees that have many decades of growth.
Several studies have been done to estimate the potential impact on global warming caused by deforestation of tropical rainforests. Loggers do not just take out mature trees for lumber. People who want to clear a place to live, work, or farm in the jungle do so by cutting and burning large portions of rainforest land.
Deforestation increases other greenhouse gases, including methane and nitrous oxide. Global warming is a foreseeable reality when the rainforest and other forests are destroyed.
Preventing global warming should first focus on cutting greenhouse gas emissions caused by the burning of fossil fuels. However, deforestation comes in a close second as a cause and should also be part of conservation efforts.
When people learn that forests are important in stopping global warming, they can help preserve them by refusing to use lumber that comes from old growth forests and rainforests. Laws have been proposed to curtail logging as a way to prevent global warming. Bans on clear-cutting, a practice that destroys acres upon acres of old growth trees, have also been suggested.
It is easy and tempting to continue to blame the deforestation problem on “those people” clearing land in the rainforests. The truth is that a tree in your neighborhood is as valuable as one in the rainforest when it comes to removing carbon dioxide. It is important to think and strategize on a global scale but it is important to also act on a local scale. We may well have more impact on the actions of those in our sphere of influence than those half a globe away. Look in your backyard, is there room for a few more trees? If so go plant some.
The Ultimate Way to Stop Global Warming

The Earth’s surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the last 50 years is attributable to human activities. Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases—primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed although uncertainties exist about exactly how earth’s climate responds to them.
Energy from the sun drives the earth’s weather and climate, and heats the earth’s surface; in turn, the earth radiates energy back into space. Atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse.
Without this natural “greenhouse effect,” temperatures would be much lower than they are now, and life as known today would not be possible. Instead, thanks to greenhouse gases, the earth’s average temperature is a more hospitable 60°F. However, problems may arise when the atmospheric concentration of greenhouse gases increases.
Since the beginning of the industrial revolution, atmospheric concentrations of carbon dioxide have increased nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have risen by about 15%. These increases have enhanced the heat-trapping capability of the earth’s atmosphere. Consequently, the temperature of the planet earth is rising.
Fossil fuels burned to run cars and trucks, heat homes and businesses, and power factories are responsible for about 98% of world carbon dioxide emissions, 24% of methane emissions, and 18% of nitrous oxide emissions. Increased agriculture, deforestation, landfills, industrial production, and mining also contribute a significant share of emissions. All these have dramatically reduce the lifespan of living earth.
The quest for efficient energy affects every country on the planet. Worldwide there is an increasing interest in developing clean, reliable alternatives to petroleum fuels. Many smart, safe, and clean alternative power sources are available in the market.
People can easily install these clean power sources at their home as alternative energy to help reducing carbon dioxide emission as well as reducing their utilities bill.
In recent year, people has come up with alternative power sources to run their cars in order to reduce the spending on petrol gas and of course, reduce the carbon dioxide emission.
Please play your part on global warming. It is easy and at the same time, you could save money!
