The economic importance of fossil fuels is well established.
The systems for extracting and transporting them have already been developed, and the fossil fuel industry employs millions of workers around the world. Switching from fossil fuels to renewable energy sources is somewhat like changing the direction of a ocean liner, taking time and a large input of extra energy.
However, there is a more important reason to conserve fossil fuels, and that's to help heal the environment.
Burning petroleum, coal and natural gas fills the air with harmful pollutants, including nitrogen oxides, sulfur dioxide, carbon dioxide, ozone and a host of hydrocarbons.
Despite what you might have heard, fossil fuels don't come from decayed dinosaurs, although dinosaurs were roaming the Earth while they were forming.
The main source of coal is decomposed plant matter, and oil comes from decayed plankton, a microscopic sea creature.
Scientists and geo- physicists, using modern prospecting equipment such as the gravimeter, magnetometer and seismograph are discovering more and more new oilfields and are greatly widening the world’s known reserves of oil.
Many of the most recently discovered fields are deep beneath the sea-floor.
The word petroleum is derived from the Latin words petra, meaning rock, and oleum, meaning oil.
It is so called because it is derived from the rocks, where it flows freely in either liquid or gaseous state.
