erosion. With the accelerated erosion, the forest begins to die. This is why positive feedback often destabilizes ecosystems unless it is counteracted. Chapter 2 1) Section 2.1 Question #2: Logging in national forests is very controversial. Describe how preservationist and conservationist views on this issue would likely differ. Since Yellowstone became the world’s first national park in 1872, the goal of these reserves and parks has become a heated topic between the two groups of preservationists and conservationists. Backed by leader and naturalist John Muir, preservationists believe that parks and public lands should truly preserve the pristine state of nature, or in other words, they should not be altered in any way. Gifford Pinchot and other conservationists, however, believe that public resources should be used to be beneficial for the largest amount of people. When it comes to the topic of logging in national forests, preservationists would clearly be against this practice, as it would ruin the pristine state of the national forests, and would want to protect the forests. Conservationists would be in favor of the practice of logging as long as it provides the greatest benefit to the greatest number of people because it would provide goods for people. 2) Section 2.3 Question #1: The economic system of the United States includes aspects of subsistence, market, and planned economies.

bartering and trading. Many people still do this in the United States today including farmers, fisherman, and hunter-gatherers, and they accomplish this by gaining a surplus of their product and then trading it for other essentials. While these are the main people that use this form of economic system, many people still use this in everyday life. For instance, people often trade products on sites like craigslist.com such as an Ipod for a television. Another form of an economic system in the United States is the market economy. The market economy is one in which production and consumption of goods and services occurs in a market with prices determined by the producer; these prices cannot be regulated by the government. An example of a market economy in the United States would be electronic companies like Apple that have their own stores and determine their own prices for their homegrown products. Another example would be open food markets with vendors that determine their own prices. The third form of an economic system in the United States is a planned economy, which is an economy that is regulated by the government. Many products in the United States have their prices regulated by the government. The most blatant products that are regulated and watched closely are gas and oil.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
