People in the world have very many needs. In order to cater for these needs a person has to have a job to do. This can be any activity that the person does and gets paid for their services. Luckily enough the earth is the biggest resource on the planet. It has numerous materials that can be used to cater for the needs of the people. Water is one of those materials. The ways of protection from electromagnetic fields are quite many.
Many of the substances on the earth are both visible and tangible in nature, this however is not so for air. Air is basically a mixture of several gases that float around in space due to their weightlessness. They are also colorless and hence invisible to the naked human eye. When in motion air is referred to as wind. Wind can be harnessed using mills to source out energy that can be used in numerous ways.
The plants in the forests also play a very major role in the maintaining the equilibrium of nature. In addition to the provision of food substances these plants also offer shelter to the wild animals and hence keeping them out of the community. Plants also help in the formation of relief rainfall that is very important to the farmers and other people that depend on rain for their water supply.
In the beginning the earth was simply one big rock or at least scientists claim so. This rock was subjected to the numerous corrosive forces in nature and it gradually broke down. This process went on for so long until there were finally fine textured pieces of rocks and these were called soils. Due to the difference in texture and other qualities as well the soils come in various kinds including clay, loamy, sandy soils and others.
Within the crust of this earth are also numerous other vital materials to the survival of man. These include the various kinds of rocks that are considered quite valuable in society. Many of these are metal ores and can be refined to get metallic elements such as iron, silver, gold, copper and numerous other precious substances. There is also a particular kind of rock known as lodestone. This is a very unique kind of stone.
When talking about nature, there are numerous other intangible things that cannot be left out. These include the various forces in nature that make the world the complete place that it is. Gravity is one of those forces. The gravitation force of pull tends to return all things from the earth to the earth. This force has numerous application in nature.
The force of magnetism is also very essential. This force originates from the core of the earth and revolves around it from the North Pole to the South Pole. Smaller versions of this magnet are the lodestone rocks that occur naturally. This theory has harnessed and the commercial creation of magnets in laboratories took precedence.
Hospitals also use electromagnetism to diagnose patients. They are also used in the removal of metallic objects out of the human body especially after the occurrence of accidents. These magnetic radiations can however be very harmful if the person is exposed to them for a very long time. There are protective gears that have been designed to cater for this.
