Battle for Trees
 
It would seem an appropriate place to begin this essay by defining what sustainable development is before going on to discuss its relationship to trees specifically, and then to some of the technology behind the sustainable development of forests, finally offering some thought on the future.
 
What is sustainable development?
 
Forest management, in its present form, adopts a position identical to that of any other managerial activity designed to accommodate a large, open system; forest management is a conscious human action that leads to a defined goal. Broadly speaking forest management is designed to ensure that it meets the needs of the present without compromising the ability of future generations to meet their own needs.
 
It can legitimately be argued that the most notable recent development in forest management is the sustainable development approach. Probably the key facet of this approach is the use of new forestry practices that allow us to conform to the stated goal of maintaining the forest ecosystem in a sustainable condition. With this approach, human activity in the forest should not negatively affect the ability of the forest to continue in virtually its present state. It should be recognised that this is a rather idealised goal and does not take into account a number of factors, such as natural climate change.
 
The definition of sustainable forest management above is fine as far as it goes, but it is vague and leaves several questions unanswered; what is a forest ecosystem, what condition was the forest in at a given point in history, how can condition be measured, how can future climate conditions be predicted.
 
Sustainable forest development should be, and indeed has to be, a multidisciplinary effort. It requires the collaboration between governments and government departments, between non-governmental agencies (NGO's) and people. It therefore involves:-
 Planning the production of wood for commercial purposes, as well as meeting local needs.
 The setting aside of areas to act as plant or wildlife reserves.
 Ensuring that the conversion of land from forest to other uses is done in a controlled and regulated way.
 Ensuring the regeneration of wasteland and the integration of trees into farm land.
 
Forests in crisis.
 
There is legion evidence for a global failure by society and governments alike to practice sustainable development of the world's forests; some have even argued for the current paradigm, despite the clear devastation being caused. Some estimate that almost half of the Earth's original forest cover is now gone, most of the destruction happening within the last 30 years, with only 20% remaining in large tracts undisturbed forest, what the World Resources Institute calls frontier forests. Forests continue to be eliminated at an alarming rate, but why is this? The main reason has to be human population growth. This is arguably the most significant threat to sustainable forest development in the world today.
 
South argued that rationally it should be impossible to maintain sustainable development of forests under a constantly growing human population. By 2100 the most conservative and optimistic estimates本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
