- Based on the text, why is this type of irrigation advantageous?
It gives farmers the capacity to control soil erosion. Through this irrigation the farmers are able to maintain the right moisture for their crops. It offers the farmers with easy way of availing nutrients and maintaining them at sufficient amount.
- What are the indications of the different-colored circles in relation to the use of irrigation?
Mixed farming is practiced. Water is specifically irrigated exactly at the plant where it is required.
- Examine a few dozen squares (four circles in most cases) closely. What kinds of erosion controls that are described in Section 10.2 can you find in this area?
Contour plowing erosion control method, Doing strip farming, and planting cover crops.
- According to Section 10.2, what is the source of energy to run these pumps? How else is this same type of energy used in modern agriculture?
The source of energy used to run irrigation pumps is biofuels. Biofuels are also used in modern agriculture machinery. In addition, biofuels are used in motor vehicles in transport industry.

- How big is Kapiti Island? Zoom way in and explore the island some. What evidence is there that this island is being preserved as a natural area?
Kapiti Island has a surface area of 19.65sqKm. The fact that the forests in the island are not cleared shows it is preserved as a natural area. Another indicator that the island is preserved as a natural area is that the island is not habited.
- How far is Kapiti from the mainland of the North Island? Does this distance make it harder or easier to keep non-native species out of the nature preserve on the island? Be sure to explain why.
Kapiti Island is 5KM off the North island of New Zealand. The location and distance have made it easier to keep non-natives out of nature (Colbourne, 2005). The reason is that the proximity to the main land is extensive and once the non-native species are eliminated at no point will there come up a new generation of the species.
- According to Section 11.3, what are some species that have been helped by protection and recovery programs in the United States, and what methods have been used?
Kiwi bird. Spotted Owl. A recovery plan which involved bringing back the native species and eliminating non-native species was used.

- What evidence can you see in this view of facilities to accommodate the millions of tourists who visit this area every year?
Very many visitors who visit turn out to harm the attraction itself. There are great parking lots. It covers 2.2 million acres of land.
- 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?
Stephen Mather encouraged tourist to use the park as a way of generating income to maintain the park. Increased number of visitor became a challenge since destruction of the attraction itself came about. It positively bore the capacity to preserve some endangered species
- How does the use of Yellowstone differ from the use of Kapiti Island? Why is this significant?
While Yellowstone National Park is playing the role of park with some level of human interference allowed Kapiti is purely preserved as a natural area. Yellowstone National Park attracts so many visitors who turn out to harm the attraction itself (Nordstrom, Ball & McCleskey, 2005). The Extensive surface area it covers protects forest ecosystem and animals who inhabit it.
