Considering natural resources, what should Americans do according to the passage?

As the 21st century begins, a number of leaders in politics, education, and other professions believe that the United States must adopt some new values to go along with the older traditional ones. What new values should Americans adopt? This is a very difficult question to answer. Certainly, a greater value should be placed on the conservation of natural resources; Americans should learn to use less and waste less.
     In addition, Americans may need to place a strong value on cooperation on a national scale to achieve important national objectives. The American idea of the national good has never been based on national cooperation but rather on the freedom of the individual, maintaining those conditions that provide the greatest freedom and prosperity for the individual.  It is far more difficult for Americans to accept shared sacrifice for the common good and well-being of the entire country. For example, although the majority of Americans believe that it is extremely important to balance the national budget and reduce the deficit, they do not want to see cuts in government programs that benefit them personally.
     The American value of competition also hinders the development of a spirit of national cooperation. Competition sometimes encourages feelings of suspicion rather than the mutual trust that is necessary for successful national cooperation.  Although Americans often cooperate successfully on the local level -- in neighborhood groups and churches, for example -- they become suspicious when the national government becomes involved. For example, on the national level, they may see themselves as part of an interest group that is competing with other interest groups for government funds. A request by the national government for shared sacrifice may be seen as coercive and destructive rather than voluntary and constructive. However, the demands of the 21st century may compel Americans to place a greater value on national cooperation to solve problems that affect them all, directly and indirectly.
