Explain sustainable agriculture and its importance
What will be an ideal response?
Answer: Sustainable agriculture is food production that can be continued indefinitely and that limits or even reverses environmental degradation. There are many definitions of what constitutes sustainable agriculture. One definition is provided by U.S. law, which describes sustainable agriculture as an "integrated system of plant and animal production" that will provide food and sustain the farm economically while also improving the environment and limiting the use of nonrenewable and synthetic resources. Such practices should sustain local soil and water quality, for example, which are necessary for the continued success of the farm and the health of farming communities and consumers. Such a broad definition obviously touches on all aspects of food: production, distribution, commerce, and consumption.

Using the graph below, construct a topographic profile from Point A to Point B. Plot index contours, and any intermediate contours necessary to accurately show significant changes in topography. The vertical exaggeration of the profile is 2x. The stereogram may be helpful in recognizing the extent of some terrace levels.
The following questions are based on Figure 49-8, a portion of the “San Clemente Island Central, California” quadrangle shown on the following page (scale 1:24,000; contour interval 25 feet; index contours drawn every fourth line; to view this map in color, go to the Lab Manual website or scan the QR code for this exercise), and the stereogram of San Clemente Island (Figure 49-7). The map and stereogram show a series of marine terraces on San Clemente Island in southern California (32°51"08"N, 118°29'58"W). The terraces have been incised by streams in several places.
