Cloning, health care, wireless telecoms The growth of urban population in this 21st century has outpaced the national average rate of population increase. What do these figures actually mean?
A brief look at the above tables will reveal the emergence of conservation simultaneously with persistently increasing changes in the number of people, the types of technology and the percentage of urban residents. While any sixty year period reveals similar changes in population, technology and affluence as those referred to above, the formative period in the creation of our national forests, monuments parks and wildlife refuges was accompanied by revolutionary changes from industrial production to the construction of vastly larger cities.
These industrial and municipal changes required an increase in the consumption of raw materials in the form of water, energy, minerals and landscape that contaminated the land, air, and water beyond the existing capacity of institutions to assure public health and safety.
Conservation reforms were seen by many advocates as a partner in the development of the nation's industrial and commercial wealth. As urban needs replaced agrarian patterns of land-use mechanized agriculture demanded irrigation and drainage to meet the growing demands.
The earliest schisms in the movement to protect natural resources from wanton destruction due to mining, logging and reclamation emerged from this clash between agrarian traditionalists and urban reformers.
In the case of Los Angeles' need for a municipal water supply, an urban aqueduct replaced the original agricultural reclamation of the Owen's Valley in the Eastern Sierra Nevada Mountains. Just Essay conservation water electricity demand for water and power in San Francisco caused a clash over the use of Yosemite National Park's water, the Owen's Valley struggle divided preservationists from conservationists.
While both groups shared a deep concern for the protection of natural landscapes the means by which the two factions viewed nature and thus sought to defend values inherent in rivers, forests and wildlife differed. Our current redefinition of conservation in the light of new technological and demographic impacts on our global environment owes its underlying unity to George Perkins Marsh's ideas of " geographical regeneration ;" to "restore the disturbed harmonies" he had imagined were manifest in the pristine natural conditions of places.
Pinchot and Muir led factions of Marsh's followers in allegedly different directions to protect nature. But they deepened our understanding of the essential balance between the need for nature in defining our cultural identity and the necessity of using natural resources to meet rising future demands for goods and services.
The rift between those who sought to stop development of resources on reserved terrain or scenic landscapes and those who pursued the sustained use of these same sources of economic wealth centered on the personalities of preservationist John Muir and conservationist Gifford Pinchot.
Concerned for the scenic beauty, natural history and cultural importance of landscape Muir and others hoped to protect national parks from exploitation of wildlife, water, or timber within the boundaries of the protected areas. Pinchot, however, as a trained forester had restored the gutted lands in North Carolina the Vanderbilt family had acquired as the Biltmore estate Photographed in the picture below.
He, unlike Muir, Pinchot was convinced of the compatibility of sustained yield forestry and scenic enjoyment of accessible resources. Although the fight over Hetch Hetchy and the Owen's valley watersheds was bitterly divisive the national movement for the protection of nature gained adherents to the cause of reform over twenty years of arguments.
Pinchot turned this once eroded and "gullied-out" —— meaning seriously eroded —— tobacco plantation into a resilient forest. It is easy to characterize the differences between Muir and Pinchot with respect to rivers, forests and wildlife. Muir viewed these features as essential sub-units of a functionally healthy landscape based on the quality and quantity of the fish in streams, the size and age of the trees, and the number and variety of the deer, panthers, bears and birds.
Pinchot, while recognizing these biotic pieces of the landscape's integrity argued that conservation could not win broad support unless economic considerations were of paramount importance. Where Muir saw fish, Pinchot recognized the cubic feet of stream flow necessary to irrigate cities or farms.
Unlike Muir, Pinchot saw forests with respect to the board feet of timber available per acre on a sustained yield basis. Where Muir argued for wildlife protection, Pinchot recognized the necessity of hunters to pay the cost of conserving wildlife refuges. While this split persists in environmental debates today the broader consensus established a national level of funding and research for the long-term management and protection of natural resources.
The national protection of our natural heritage by applying science to the renewal of landscape is one product of these early conflicts in the formative period of the conservation movement. The precise circumstances that brought conservation to the national level of political reform have changed.
Two hundred million more people dwell in and demand thirty times the amount of resources per person as did the generation of Americans. To maintain our current affluent standards of living each American, for example, uses the equivalent of 10 acres of land each year! Despite these changes such a direct impact has generated problems only hinted at years ago.
Pollution, habitat loss, decline in species numbers and variety, and shortages in certain vital industrial materials has transformed these common conflicts over conservation from mere regional skirmishes into international negotiations over the future of forests, climate change, population planning and biological diversity.
This changing conflict over use and reservation of resources is the result of demographic and technological forces that have demonstrated the links between economics and ecology that once troubled wildlife biologist Aldo Leopold.
He conceived of ecology as a round river whereby the movement of moisture from land to air and into water is a metaphor standing for how rivers, forests, wildlife and humans all shared the same sources of well-being. The health of the ecosystem he believed was embedded in the beauty and functional integrity of places.
These sources of biotic wealth must be restored in order for humankind to advance morally as well as economically. Like any circular relationship, Round River, represents the facts that whatever we do to the surroundings we inhabit, we ultimately do to one another.Water conservation essay is the paper dedicated to the urgent problem of the contemporary world about the necessity and possible ways of water protection.
