What is the worlds most valuable resource?

Answer 1

All Natural Resources that mankind makes use of (and there are many uses; for example as jewelry, or by industry etc...) are valued.

There are many such resources (such as oil, gas, gold, coal etc...) and to provide a comprehensive list would perhaps be a little tedious.

However this question does raise a necessary and interesting further question as to what we mean by "valued". In a strict monetary sense of the value of a given amount of a resource, the value is usually, and understandably, linked to the scarcity of the resource and the difficulty required to extract it (the economics of supply and demand are involved).

Though we should reflect that this is not the only way to measure something's value. A given volume of gold may presently have a higher monetary value than, for example, the same volume of oil. One can not for a moment though necessarily conclude that gold is more valued than oil. Modern society would be impossible without oil, the same is not true for gold. And as oil becomes more scarce, the price (unless a substitute has been found) will skyrocket to reflect this.

Answer 2

probably diamonds, gold, iron ore..... something like that
