D) undiscovered lands will provide plenty of natural resources
Explanation:
Before the end of the Second World War, there were no studies published in a massive way in order to point out the need to conserve nature for new and future generations. This represented a paradigm of the economy that observed ecology in a profound way, with higher values to human beings than to forests. At the time, the concept of the main economy consisted of the fact that natural resources are not scarce, starting from this concept began to establish conservation methods to preserve mineral resources.
Conservation methods are needed worldwide for several reasons. The factors that highlight the need to support these conservation methods are:
global population growth
global capacity to provide sufficient food
geographical mismatch between food demand and supply
