People naturally require quite a number of things. These things are commonly referred to as the needs of man. These needs can either be basic or secondary to the person. The basic ones are those that the person cannot survive without having adequately. The secondary needs on the other hand serve as a way of making the person more at home and comfortable. The characteristics of good greenhouse fans are quite numerous and vital.
People have for ages used the numerous resources in nature to cater for their many needs. This is done both directly and indirectly as well. The needs of the people include food, housing, clothing, security and finally medical care. Each and every person should be able to have adequate resources to cater these basic human needs. The food that we eat is supposed to provide us with the energy to carry out other activities.
The earth has several resources that can be exploited to create wealth. This wealth can then be used to cater for the needs of the people. Water is one of these resources. This material has very many uses in the community. These range from direct consumption, cleaning the house to washing clothes and cooking in the home. Commercially water is used to make numerous beverages that are sold for a financial benefit.
Air is another very crucial element in nature. This air is basically a mixture of several other independent gases that exist freely in nature. This material is colorless and also not physical and therefore cannot be seen or touched. It presence can only be told by the sensation of its presence and the effects on other elements in nature. Air is very important for the existence of the human species. Metabolism in the humans cannot occur without oxygen.
Oil is one of the many materials that are situated under the surface of the earth. This oil is crude when extracted but it can be refined into several other vital products such as petroleum, diesel, kerosene and many others. Each one of these elements has many important applications in the community. Petroleum for starters is responsible for powering most of the machines that we use for transport and communication.
Eventually the earth is another element of such paramount importance. It supports all other things in nature. Everything else on this planet rests only when on the surface of the earth. The earth is made of rocks, stones and soils as well.
This practice is basically the backbone of any economy. Many of the other economic activities rely upon agriculture for their inputs and other raw material needs as well. This practice employs the highest number of people ever. Commercial farming is not easy however and requires a smart farmer.
