Methods of Conservation
The challenge of conservation is to understand the complex connections among natural resources and balance resource use with protection to ensure an adequate supply for future generations.

These include reducing consumption of resources; protecting them from contamination or pollution; reusing or recycling resources when possible; and fully protecting, or preserving, resources.
Consumption of natural resources rises dramatically every year as the human population increases and standards of living rise. Between 1950 and 1990 the world population doubled to 5.3 billion, with nearly 80 percent living in developing, or poorer, nations. The large, developed nations, however, are responsible for the greatest consumption of natural resources because of their high standards of living.
