Global warming population growth

Regarding the annual population growth, daily energy requirement, environment problems such as air pollution and global warming caused by fossil fuels (mainly due to emission of carbon dioxide and sulfur dioxide), high price of petroleum fuel, and reduction of the petroleum reservoir, experts are trying to find novel biofuel production methods to replace petro-diesel with biofuel. 

Powell, James Lawrence. Dead Pool Lake Powell, Global Warming, and the Future of Water in the West. Berkeley University of California Press, 2011. An excellent, fact-filled account of the myriad issues surrounding the huge growth of population and the competition for water among those in the Colorado River watershed. 

The availability of renewable feedstock is continuously being debated. There are governmental mandates and subsidies that stimulate growth of the field, but also there are public concerns that biofuels do not, or only to a limited extent, contribute to a reduction in global warming. Further, the growing world population needs more agricultural products for food and animal feed, and the competition between food and fuel presents difficult dilemmas. 

Carbon dioxide is considered as a main greenhouse gas. Its contribution to global warming can be pointed up by correlations between the evolution of CO2 in atmosphere and the average earth temperature [1]. Since the eighteenth century the concentration of CO2 has approximately risen from 280-380 ppm when simultaneously temperature has increased by 0.6 K. Anthropogenic sources of carbon dioxide represents currently about 25 Gt per year. If we consider constant industrial development and population growth in the world, the emissions of carbon dioxide will...
