Is Over-population the Problem?

The impact (I) of resource use in the world is a result of the relationship between:

Consumption levels per person (C);

The technology used to produce the goods and services consumed (T); and

Population numbers (P).

This complex relationship is often shown by the formula:

I = C x T x P
