Natural resources info

A natural resource is anything that people can use which comes from nature. People do not make natural resources, but gather them from the earth. Examples of natural resources are air, water, wood, oil, wind energy, hydro-electric energy, iron, and coal.

We often say there are two sorts of natural resources: renewable resources and non-renewable resources.

A renewable resource grows again and comes back again after we use it. this is like a rebounding ball . For example, soil, sunlight, water and wood are renewable resources. A non-renewable resource is a resource that does not grow and come back, or a resource that would take a very long time to come back. And this one is like a sin once done is done. For example, When we use coal, there is less coal afterward. One day, there will be no more of it to make goods. The non-renewable resource can be used directly (for example, burning oil to cook), or we can find a renewable resource to use (for example, using wind energy to make electricity to cook). It is important to conserve (save) non-renewable resources, because if we use them too quickly there will not be enough.

Most natural resources are limited. This means they will eventually run out. A perpetual resource has a never-ending supply. Some examples of perpetual resources include solar energy, tidal energy, and wind energy. Other examples are salt, stone, magnesium, and diamonds.

Some of the things influencing supply of resources include whether it is able to be recycled, and the availability of suitable substitutes for the material. Non-renewable resources cannot be recycled. For example, oil, minerals, and other non-renewable resources cannot be recycled.

Demand

The demand for resources can change with new technology, new needs, and new economics (e.g. changes in cost of the resources). Some material can go completely out of use, if people do not want it any more. Demand of natural resources is very high, but availability is very low .

Availability

All places have their own natural resources. When people do not have a certain resource they need, they can either replace it with another resource, or trade with another country to get the resource. Some resources are difficult to find, so people sometimes fight to have them (for example, oil resources).

When people do not have some natural resources, their quality of life can get lower. So, we need to protect our resources from pollution. For example, when they can not get clean water, people may become ill; if there is not enough wood, trees will be cut and the forest will disappear over time (deforestation); if there are not enough fish in a sea, people can die of starvation. Some examples of renewable resources are wood, solar energy, trees, wind, hydroelectric power, fish, and sunlight. So humans should begin saving their natural resources. Or else, all will be lost and it will be difficult for humans to survive

I hope u get what ur looking for and I wish u give me brainlist But I know u won't cuz everyone say that . But thank you so much if u put for me and It would be a very appreciated from you and again thank you so much

Sincerely caitlin,

thank youuu
