This is because oil takes a long period to renew. It has to take organic matter to live, die and decay to form oil. Decaying plants and animals form the basis for fossil fuels. It is estimated that the process of oil formation takes 300 million years (Pfeiffer 287). The combustion of these fossil fuels provides the energy that man needs. Energy sources include oil, coal and hydroelectric power. Non-renewable resources are resources that do not renew themselves at a sufficient rate for sustainable extraction. Examples of these resources include carbon-based and derived fuel. The organic material becomes fuel oil, gas after it is subjected to varying amounts of heat and pressure. Fossil fuels such as coal, natural gas and petroleum are other examples of renewable sources. These resources contribute significantly to environmental degradation because of inability to be reused after extraction (Arthur 1510). Humans extract other non-renewable sources of energy such as minerals and metal ores since they exist within the earth’s crust.

The deposits of these metal ores can be extracted by humans for their economic gains w ithin the human-time
