NAME:
Living beings depend on resources found in nature to survive, such as water and food. Human beings have developed sophisticated techniques for extracting and using natural resources, modifying the environment around them.
We can call natural resources all the elements available in nature and that can be used by living beings. For example: soil, solar energy, air, ores, water and even plants and animals.
Natural resources can be used in different ways. They are present in food, constitute the raw material of products and are also used for energy production.
Natural resources can be classified as non-renewable or renewable, according to their origin and availability in nature.
Non-renewable resources take millions of years to form in nature, exist in finite amounts and can be depleted with use. Renewable alternatives to replace them should be considered. This is the case of gasoline and diesel oil, derived from petroleum. As oil is a finite resource, several researches seek to find products that can replace it, such as ethanol and biodiesel, fuels derived from plants.
Renewable resources are those that are not depleted with use, that can be renewed. But be careful! Nature has the ability to regenerate water, for example, but the amount of drinking water is increasingly decreasing because of pollution.
Soil can also become unproductive if it is not preserved.
