growth rate (lower birth rate and higher mortality). All three projections are
shown in Figure 3-10.
Surely, the question of our population level and the world's human carrying
capacity must be an important one. If we are to continue to feed, shelter, and
clothe ourselves into the next century, we must plan now. We must begin to
better manage our natural resources. We must learn how to improve our natural
resource management skills and tools.
There is no immediate danger of worldwide starvation or death from disease. We are not running out of natural resources, but the challenge is before us.
Managing our natural resources carefully is more important now than ever before.

RESOURCE USE
All living things depend on their ecosystem for survival. With modern transportation and communication, the world is our ecosystem. We must derive everything we need to have from that system, and it is simply not possible to sustain
the number of people alive today without altering that ecosystem. Our very
survival depends upon our use of natural resources.
On the other hand, the abuse or misuse of the resources nature provides
cannot be allowed. Our society must have food in large quantities. Such large
amounts of food can only be produced by modern, large-scale farming, but the
farmer must not allow the soil to be destroyed by erosion. It is possible to produce
agricultural products with little damage to the soil. Soil erosion and its control
are discussed in Chapters 5 through 7.
Our homes, farms, and factories produce vast amounts of waste. In the past,
this was simply thrown into gullies or poured into rivers. As the amount of waste
increased, waste disposal and water pollution have become serious world problems. Chapters 9 and 14 deal with these topics.
Metals and minerals can be recycled and used more than once. We can seek
out new substitutes and new supplies of these exhaustible resources. In the end,
