From the point-of-view of the variation and flexibility of the species such cultivated woody crops rank as no more than cornfields. While the tree farms are conveniently be stretched on the private lands, national forests those are considered priceless reservoirs of most of the biological diversity of the nation cannot expand so easily. The commercial logging is considered as the greatest danger for survival of the national forest system. The timber sales are growingly concealed beneath the post fire recovery and fire prevention missions, forest health initiatives and restoration programs. (Endangered Forests: Endangered Freedoms)
Wetlands disappearing
Declining wetlands and reservoir construction are having spectacular influences on a global scale. (the Importance of Wetlands and the Impacts of Reservoir Development) the data of USF & WS reveals that the United States added 2.3 million acres in ponds and inland mudflats during the period of mid 1950s and mid1970s. The country added about 1.4 million acres in inland lakes and reservoirs added about 200,000 acres of sub-tidal territory. But America has to part with 11 million acres of palustrine wetlands- those are on the verge of natural conversion into uplands. Such natural conversion is a significant phenomenon to think of. The fact however settles down that there prevails a natural inclination towards conversion of wetlands. Moreover, the Fish and Wildlife Service data are quite misleading. During the period between mid-1950s and 1970s about 9.2 million acres of wetlands were observed to have disappeared. As the Service, about 87% of such disappearance is attributed to the Agricultural purposes while about 1.2 million were disappeared due to urban development and other unidentified sources. However, during the period of mid-1970s and 1980s merely 3 million acres of wetlands have been lost. Out of that farming included 1.6 million acres, urban development comprised 200000 acres and others accounted for about 1.2 million acres. (Our Disappearing Wetlands)
California has lost the greatest percentage of 1%, but 21 other states have covered or tilled at least fifty percent of their original wetlands. Fast developing Florida has filled in the most acreage -- a land size bigger than all of Massachusetts, Delaware and Rhode Island taken together. About three-quarters of the bottomland hardwood swamps of Louisiana towards south have disappeared while the farmers tilled the land those were drained by the U.S. Army Corps of Engineers much before. (Paradise Lost: America's Disappearing Wetlands) a large part of the problem in vanishing wetlands has direct influence from humans. Such influences involve wetland disappearance as a result of urbanization that is particularly evident in case of Southern United States, deforestation and logging, conversions for rice field paddies, conversion of new farmland and even the occasional fish farm. (the Importance of Wetlands and the Impacts of Reservoir Development)
The shopping centers and riverfront homes credibly grow on damp land without the normal requirements: indicating the public or seeking permission from the U.S. Army Corps of Engineers, the agency in charge of controlling the use or destruction of wetlands. The vulnerability of wetlands seems in its simplest form seem to fume to a curious circle. Human necessitates a place to live, work, shop. The search for reasonably priced, attractive alternatives-that may be in former wetlands. The developers construct homes where the demand depicts the desire of the people want to live. Therefore, more and more people transit into new ranch houses in the former wetlands. Increasing number of builders constructed there. It is predicted of the suburbs where herons once stood like statues calmly anticipating for a meal to float by. About two Americans now reside on or near the coast necessitating an average of one half acre of land apiece for new schools, post offices, and other public services. About 70% of Americans are expected to inhabit on the coast by 2050. Hence, the stress is ever growing. (Paradise Lost: America's Disappearing Wetlands) When more wetlands are gradually vanishing there could be some prospectively serious global influences. It is anticipated that there will be serious affects on wetlands from the rising seal levels in consequence to the global warming.

Ignoring Global warming
During the past one century, global temperatures have increased by 0.6 degrees Celsius. Some of the recent decades are considered to be the warmest, became evident when people started to maintain temperature records- varying the face of the planet. Global warming could curtail the agricultural productions, enhance the sea levels and entail more extreme weather. The study of the global warming involves great ambiguity. The developing countries are accountable for just over one-third of the greenhouse-gas emissions. However, they emit less than one-fifth per person as do the industrialized...
