The need arises for sea transport when one country has a shortage of something‚ such as iron-ore‚ grain or coal‚ and another country has a surplus. These three types of commodities make up the dry-bulk industry. As such‚ when analysing the demand level of sea transport‚ we realize the overall level of demand for sea transport activity has

Part One - Introduction Fossil Fuels are the most important energy sources in our world today. The overwhelming majority of the huge amount of energy used in the world comes from the burning of three major fossil fuels: coal‚ petroleum‚ and natural gas. Fossil fuels are a non-renewable source of energy‚ and there is no other . They are formed over a very long period of time; the fossil fuels on earth today were formed from plants and animals that lived up to 300 million years ago. These fossil

Because they cannot be renewed fast enough to keep pace with consumption‚ they are considered non-renewable and are the most commonly used type’s energy. Fossil fuels were formed over millions of years when decomposed plant and animal matter were buried by layers and layers of the earths crust and then it was transformed into carbon-rich material that is used as fuel.

To what extent does Methane effect climate change and what are the uses and limitations of science in addressing this issue? Methane is influenced by various natural and anthropogenic factors such as landfills‚ farms‚ drilling for natural gas‚ and coal mining. All of these factors that generate Methane emissions create ground level o-zone which is not only hazardous for our health‚ but it is a great concern for our climate. EPA is one of several organizations that plays a significant role in encouraging
