A reduction in coal burning can be achieved by either using conservation programs to decrease demand (such as mandating the use of energy-efficient appliances and light bulbs) or finding cleaner generation methods (such as water, wind, or solar power).";

In the absence of government intervention, no farmland is preserved (QMKT = 0 in Figure 16-7). This is much less than the socially optimal level, which occurs where MSC = MSB > 0; society wants some positive quantity of farmland preserved.";
