The root cause of global warming is due to excessive production of CH4, CO2, SO2, NO2 gases in the atmosphere. If not controlled, it will end the future. Biotechnology can be used to minimize these gases by the production of Biodiesel, Biofuels etc. Biodiesel can be produced biotechnologically by algal culture (algal oil production). Micro-algae have much faster growth rates and the per unit area yield of oil from algae is estimated to be from between 5,000 to 20,000 Gallons per acre, per year; this is 7 to 31 times greater than the next best crop, palm oil. Biodiesel reduces emission of CO by approximately 50% & CO2 by 78% on a net life cycle basis in comparison with petroleum diesel. Some fresh water and marine algae are also a good source for Biodiesel, since they contain a high percentage of hydrocarbons for example: Botrycoccus braunii contain as much as 75% of its biomass in form of hydrocarbon. For large scale production of a suitable alga for hydrocarbon yield can be produced by producing new strain varieties of algae by the application of recombinant DNA technology. Next we can reduce the green house gases by eliminating the conventional fuels ( i.e fossil fuel - basically used by village people ) by Biogas and Biohydrogen. Biohydrogen combustion yields only water vapours, no pollutants. Finally, by manufacturing biofertilizers, biodegradable products by the application of Biotechnology we can keep environments clean because all these products are ecofriendly.
