Carbon dioxide (CO 2 ) is the most prevalent greenhouse gas. This is because when trees die, they release the stored carbon. Deforestation is the permanent destruction of forests in order to make the land available for other uses. Trees can help, though. 300 billion tons of carbon, 40 times the annual greenhouse gas emissions from fossil fuels, is stored in trees, according to. The deforestation of trees not only lessens the amount of carbon stored, it also releases carbon dioxide into the air. The WWF states that scientists estimate that a third of the world s arable land has been lost to deforestation since 1960. Tree roots anchor the soil. These tactics leave the land completely barren and are controversial practices. Clear cutting is when large swaths of land are cut down all at once.

Food and Agriculture Organization (FAO). Some other statistics: Deforestation occurs around the world, though tropical rainforests are particularly targeted. It also has negative consequences for medicinal research and local populations who rely on the animals and plants in the forests for hunting and medicine. Water cycle: Water vapor is also considered a greenhouse gas. The impact of deforestation on the exchange of water vapor and carbon dioxide between the atmosphere and the terrestrial land surface is the biggest concern with regard to the climate system, Some of them include shifting the human population to a plant-based diet. Gas molecules that absorb thermal infrared radiation are called. According to the, deforestation releases nearly a billion tons of carbon into the atmosphere per year, though the numbers are not as high as the ones recorded in the previous decade. As a result, Haiti has endured more extreme soil erosion, flooding and landslide issues. Life quality: The country with the most deforestation is Indonesia. Over the past 16 years, Alina has covered everything from Ebola to androids while writing health, science and tech articles for major publications. A forestry expert quoted by the describes clear cutting as an ecological trauma that has no precedent in nature except for a major volcanic eruption. Burning can be done quickly, in vast swaths of land, or more slowly with the slash-and-burn technique. Daley said. This can decrease local water quality and contribute to poor health in populations in the area. Many believe that to counter deforestation, people simply need to plant more trees. Though a massive replanting effort would help to alleviate the problems deforestation caused, it would not solve them all. Reforestation won t completely fix the damage, though. To date, she has been a volunteer firefighter, a dispatcher, substitute teacher, artist, janitor, children s book author, pizza maker, event coordinator and much more. Entails cutting down a patch of trees, burning them and growing crops on the land. If greenhouse gases are in large enough quantity, they can force climate change, according to Daley. In the Amazon, more than half the water in the ecosystem is held within the plants, according to the National Geographic Society. Soil erosion: For example, of continental United States

Without trees, the soil is free to wash or blow away, which can lead to vegetation growth problems. She has multiple health, safety and lifesaving certifications from Oklahoma State University. When the soil becomes less nourishing and weeds begin to reappear over years of use, the farmers move on to a new patch of land and begin the process again. Deforestation is considered to be one of the contributing factors to global climate change. Planting these types of trees can cause further soil erosion because their roots cannot hold onto the soil. The situation in Haiti compared to the Dominican Republic is a great example of the important role forests play in the water cycle, According to Michael Daley, associate professor of environmental science at Lasell College in Newton, Massachusetts, the No. 1 problem caused by deforestation is the impact on the global carbon cycle. Greenhouse gas, according to the (EPA). When they are degraded, it can set off a devastating chain of events both locally and around the world. Loss of species: The reports that half of the trees illegally removed from forests are used as fuel. Some other common reasons are: Common methods of deforestation are burning trees and clear cutting. Both countries share the same island, but Haiti has much less forest cover than the Dominican Republic. The organization uses satellite technology, open data and crowdsourcing to detect and alert others of deforestation. Reforestation will not help with extinction due to deforestation, either. Unfortunately, we have already diminished the population of many species to such an extreme that they might not recover, even with a massive reforestation effort, Predicts that if current deforestation levels proceed, the world s rainforests may be completely in as little as 100 years. Indigenous forest has been removed since 1600. Countries with significant deforestation include Brazil, Indonesia, Thailand, the Democratic Republic of Congo and other parts of Africa, and parts of Eastern Europe, according to, a United Nations Environment Program collaborating center. Daley told Live Science. In addition to reforestation, some other tactics are being taken to counteract or slow deforestation. Deforestation is the second largest anthropogenic (human-caused) source of carbon dioxide to the atmosphere, ranging between 6 percent and 17 percent. ( )Carbon isn t the only greenhouse gas that is affected by deforestation. Changes in their atmospheric concentration will have a direct effect on climate. Deforestation has decreased global vapor flows from land by 4 percent, according to a study published by the. While oxygen (O 2 ) is the second most abundant gas in our atmosphere, it does not absorb thermal infrared radiation, as greenhouse gases do.

Even this slight change in vapor flows can disrupt natural weather patterns and change current climate models. Forests are complex ecosystems that affect almost every species on the planet. Seventy percent of the world s plants and animals live in forests and are losing their habitats to deforestation, according to National Geographic. It is still necessary to avoid buildup in the atmosphere. Since the last century, Indonesia has lost at least 15. 79 million hectares of forest land, according to a study by. Though deforestation has increased rapidly in the past 50 years, it has been practiced throughout history. They absorb rain fall and produce water vapor that is released into the atmosphere. Their online community is also encouraged to share their personal experiences and the negative effects of deforestation. Additional reporting by Jessie Szalay, Live Science Contributor Additional resourcesAlina Bradford is a contributing writer for Live Science. This would lower the need for land to be cleared for raising livestock. has also initiated a project to counteract deforestation through awareness. The World Resources Institute estimates that most of the world s remaining indigenous forest is located in Canada, Alaska, Russia and the Northwestern Amazon basin. There are many causes of deforestation. Trees also lessen the pollution in water, according to the, by stopping polluted runoff. Alina s goal in life is to try as many experiences as possible. Trees are important to the water cycle. An estimated 18 million acres (7. 3 million hectares) of forest, which is roughly the size of the country of Panama, are lost each year, according to the United Nations After a clear cutting, cash crops like coffee, soy and palm oil are planted. In 2012, CO 2 accounted for about 82 percent of all U. S. Loss of habitat can lead to. For example, Daley points out that forests cannot sequester all of the carbon dioxide humans are emitting to the atmosphere through the burning of fossil fuels and a reduction in fossil fuel emissions. Soil erosion can also lead to silt entering the lakes, streams and other water sources. The ash from the burned trees provides some nourishment for the plants and the land is weed-free from the burning. Said Daley. Causes and effects of childhood obesity essay.
