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.
The survival requirement s of a person are not so many they are however very crucial and expensive as well. The person has to have food supplies on a daily basis for the provision of energy and other nutrients for body growth and development. The person has to have adequate clothing as well for the cold times. A house is another very important possession for any person in this world.
The resources in nature include the water. Water is a very simple yet highly unique element in nature. It is mainly sourced from the various water bodies in the community. It can either be fresh or salty in taste. Fresh water comes from the rivers and streams while salty water on the other hand is sourced from the closed bodies such as lakes, seas and oceans as well.
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.
In order for agriculture to be successful, research work is very important. This is the reason as to why people find it necessary to create greenhouses where various plants can be planted and tested under certain controlled conditions. This greenhouse should be properly lit and fans should be in place to cater for aeration.
