- Economic factors.
| Cultural differences. People in different times and places may have different ideas about whether something supplied by nature is or is not a natural resource. Years ago, for example, Native Americans viewed the Great Plains of the United States as hunting grounds, while settlers moving west across the frontier saw the Great Plains as a place for farms and towns.
Even people in the same culture may view and use resources differently. A farm family may see a forest as a source of winter warmth and cooking fuel. Loggers may see the forest as a place to find jobs. Campers may see the forest as a recreational area in which to spend vacations. New technology also affects how people value and use natural resources. Before tractors and trucks, farmers considered mules to be a highly valued resource. Mules pulled plows and carried crops to market. Today tractors and trucks do the work once done by mules. For this reason, people value mules less than they did in the past. Technological change also creates uses for previously unvalued natural materials. In the 1700s people did not use uranium ores and did not value them as natural resources. Uranium ores gained value only after modern advances made them useful as a resource for nuclear energy. Economic factors. These factors also play an important part in the way people use natural resources. Scarcity and rising prices have always led people to seek cheaper substitutes for costly resources. In colonial days, for example, people burned whale oil for lighting. As demand for whale oil rose, more and more whales were hunted. Eventually overhunting made whales harder to find and prices rose. People then looked for cheaper substitutes. In time they found a way to make kerosene from petroleum. Because kerosene cost less than whale oil, it quickly replaced whale oil as a lighting fuel. Another factor that affects the use of natural resources is geopolitics - the relationship between geography and political policy. The international trade of scarce minerals provides an example of the importance of geopolitics in today's world. Most mineral deposits are unevenly distributed across the earth. This uneven distribution has resulted in increased world trade as countries lacking certain mineral resources buy what they need from other countries. Depending on the circumstances, a price increase or interruption in supply could result in great changes in the country importing the mineral. Geopolitics is becoming an increasingly important force in the world today. 1. Why are natural resources important? 2. How can the use of natural resources change a) the natural landscape and b) the cultural landscape? 3. What different factors affect the value and use of natural resources? 4. How did technological advances and economic factors change the way people met their needs? жүктеу/скачать 25,52 Kb. Достарыңызбен бөлісу:
