non-renewable resources

Answer 2

Explanation:

1. Conservation of resources

Resource conservation means using the available resources carefully and giving them time to get renewed. Sustainable development means balancing our present needs of using resources without compromising the ability of future generations to meet their own needs.

2. Man-made resources

When humans use natural things to make something new that provides utility and value to our lives, it is called human-made resources. For instance, when we use metals, wood, cement, sand and solar energy to make buildings, machinery, vehicles, bridges, roads etc. they become man-made resources.

3.Non-renewable resources

A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource. Fossil fuels such as oil, natural gas, and coal are examples of nonrenewable resources. ... Renewable resources are the opposite: Their supply replenishes naturally or can be sustained.
