Question

Humans depend upon a variety of Earth's natural resources. Certain resources should be conserved because humans are able to consume them much faster than they can be replaced by natural processes.

Which of the following is a resource that should be conserved?
wind coal
oil (petroleum)
natural gas sunlight geothermal energy

Answer 1

Step-by-step explanation:

coal

oil

natural gas

These are the big three. Of the three, oil is the most important. It is relatively clean burning -- relative to coal which might be more abundant.

Natural gas is more abundant, but it is awfully hard to store.

If all else fails, coal, but coal is a very dirty burn.
