Deforestation Essay

People are deforesting the planet for thousands of years, primarily to clear land for crops or stock. though tropical forests square measure for the most part confined to developing countries, they square measuren’t simply meeting native or national needs; economic economic process means the wants and desires of the worldwide population are bearing down on them also. Direct causes of deforestation square measure agricultural growth, wood extraction (e.g., work or wood harvest for domestic fuel or charcoal), and infrastructure growth like road building and urbanization. seldom is there one direct cause for deforestation. Most often, multiple processes work at the same time or consecutive to cause deforestation.The single biggest direct cause of tropical deforestation is conversion to cropland and pasture, mostly for subsistence, which is growing crops or raising livestock to meet daily needs. The conversion to agricultural land usually results from multiple direct factors. For example, countries build roads into remote areas to improve overland transportation of goods. The road development itself causes a limited amount of deforestation. But roads also provide entry to previously inaccessible—and often unclaimed—land. Logging, both legal and illegal, often follows road expansion (and in some cases is the reason for the road expansion). When loggers have harvested an area’s valuable timber, they move on. The roads and the logged areas become a magnet for settlers—farmers and ranchers who slash and burn the remaining forest for cropland or cattle pasture, completing the deforestation chain that began with road building. In other cases, forests that have been degraded by logging become fire-prone and are eventually deforested by repea...

The FAO report does not compile statistics for tropical forest regions as a whole, but the country-by-country and regional-scale statistics provide a grim picture. The scope and impact of deforestation can be viewed in different ways. One is in absolute numbers: total area of forest cleared over a certain period. By that metric, all three major tropical forest areas, including South America, Africa, and Southeast Asia, are represented near the top of the list. Brazil led the world in terms of total deforested area between 1990 and 2005. The country lost 42,330,000 hectares (163,436 square miles) of forest, roughly the size of California. Rounding out the top five tropical countries with the greatest total area of deforestation were Indonesia, Sudan, Myanmar, and the Democratic Republic of Congo.
