Which of the following is NOT considered a natural resource?

Computers are not considered a natural resource because they are human-made products that require various materials and technologies for their production. Natural resources are typically defined as materials or substances that occur in nature and can be utilized for economic gain or support life. In contrast, gold, water, and diamonds are all found in nature without direct human intervention and can be extracted and used directly or processed into usable forms.

Gold is a valuable metal that is mined, water is essential for life and can be found in natural bodies such as rivers and lakes, and diamonds are naturally occurring gems that are also mined. Therefore, the classification of computers as a human-made artifact distinguishes them clearly from true natural resources.
