Document Summary

Chapter 7: create a linked system of natural areas and parks. Most obvious and important regional environmental system: watershed. Linked natural areas and parks reduce ghg. Stream systems + necessary forested buffers reduce heat island effects. Even in new neighborhoods b/c of shade they provide air cooling they produce. Even tho takes away 25 acres of trees to isolate avg. annual amount of carbon produced by 1 american. Linked parks/natural areas = connect urban districts for human purposes. Stream systems = dendritic therefore, path system organized around will allow pedestrians/bikes to access every part of urban district (branch tips of streams reach every corner of watershed) Provide comfortable, shaded way to travel long distances on foot/small-wheeled vehicles. Logical/organic way to make walking/biking more pleasant & convenient. Frederick law olmsted and linked natural areas and parks.

This part of the activity focuses on the practice of setting aside natural areas for ecological, cultural, and recreational purposes. In some wilderness areas, human use of the area is kept to an absolute minimum. But, it can be expensive and difficult to maintain wild areas with little human influence. The areas are so beautiful that they attract many visitors, who in turn can harm the natural attraction itself. Vehicles can be a particularly difficult problem in natural areas such as this. Yellowstone Park was established in 1872 and has more than 2.2 million acres. It remains one of the most popular units of the U.S. National Park system and has more than 3 million visitors each year. Instructions Review the Case Study at the beginning of Chapter 12, entitled âProtecting Forests to Prevent Climate Change,â and Section 12.3, entitled âParks and Preserves.â Consider reasons it is important to maintain forest ecosystems. Open Google Earth, and in the search box enter Old Faithful, Yellowstone National Park, WY. Click Search. According to the textbook, how and why did Stephen Mather, the first U.S. National Park Service director, encourage tourist use of the parks? What were some positive and negative results?

Environmental sustainability is concerned with the relationship of a company to its environment and its use of finite natural resources since corporations are the biggest users of Natural Resources managing and maintaining these resources is critical for the long-term economic interests of Corporations all companies are part of a business ecosystem whose economic health depends on the availability of Natural Resources in response most major companies have begun to change how they do business emphasizing on the use of sustainable business practices.

Deforestation is an issue caused by the continued development of modern society by way of ever-increasing space and resource demands. Deforestation is especially dangerous to the carbon cycle as trees are vital to the process of through the absorption of carbon dioxide and other gasses. A single, average-sized tree can produce a day's oxygen for four people (Evans 2001). Deforestation is dangerous for the environment for many more reasons, including increased unnatural soil and land erosion, excess amounts of ash (through forest burning), and effects on the hydrologic cycle.

In order to reduce deforestation's harm on the environment, we must protect as many areas as possible, preventing unnecessary development from getting out of control. There are likely many opportunities for technological advancement in the forest removal process to help with the issues of deforestation.

It is important that excessive tree and forest removal be prevented in the interest of preserving our biosphere.
