Natural Resources Explained

Natural Resources Explained

Key Concepts

Renewable Resources

Renewable resources are natural resources that can be replenished or replaced within a human lifetime. Examples include sunlight, wind, water, and trees. These resources are sustainable because they can be used repeatedly without being depleted.

Think of renewable resources as a never-ending supply of toys. Just like you can play with your toys over and over again, renewable resources can be used continuously because they naturally replenish themselves.

Non-Renewable Resources

Non-renewable resources are natural resources that exist in fixed amounts and cannot be replenished once they are used up. Examples include fossil fuels like coal, oil, and natural gas, as well as minerals like gold and iron. These resources take millions of years to form and are finite.

Imagine non-renewable resources as a limited number of candies in a jar. Once the candies are gone, they are gone for good, just like non-renewable resources that cannot be replaced once they are used up.

Sustainable Use

Sustainable use refers to the practice of using natural resources in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs. This involves managing resources carefully to ensure they are available for long-term use.

Think of sustainable use as sharing your toys with your friends. You take turns and make sure everyone gets a chance to play, so the toys last longer for everyone. Similarly, sustainable use ensures that resources are available for future generations.
