Need to Invent an Appropriate Technique to Extract Hydrogen from Non-polluting Sources - Research Paper Example Human activities are increasing the natural levels of those gases, by emitting carbon dioxide from the burning of fossil fuels such as coal, oil, and natural gas; methane and nitrous oxide produced by agricultural activities and changes in the use of land use; and by some industrial gases that do not occur naturally but are long-lived in the atmosphere. Emissions of poisonous gases from vehicles are also constantly polluting the air. In fact, a large proportion of harmful gases in the atmosphere are being emitted from the vehicles. With the development of civilization, the rate of transportation has also increased. Today, most of the vehicles are run by fossil fuels, like petrol, diesel, coal etc. the burning of these fuels emit hazardous gases in the atmosphere and enhances the risk of global warming. In order to protect the Universes from the curse of global warming, the immediate need is to reduce the emission of those gases that are responsible for global warming. In order to red uce the emission level, the prime requirement is to discover alternative sources of energy other than fossil fuel. The vehicles, therefore also need to be run by the energy whose production does not need petrol, diesel or coal. Scientists are experimenting with several alternatives to the traditional source of energy for the vehicles. Fuel cell cars seem to be an appropriate solution to the problem of global warming.   In the last twenty years, scientific knowledge has led to the understanding that anthropogenic, human-made actions were responsible for the changes in global climate. Those changes are a consequence of the emission and accumulation of greenhouse gases on the atmosphere.
