ENVIRONMENTAL IMPACT RATING OF FOSSIL FUEL POWER STATIONS

Environmental Effects of the Fossil Fuel AgeBy John McNeill Over the last two centuries, human activity has transformed the chemistry of Earth’s water and air, altered the face of Earth itself, and rewoven the web of life. Why has this time period, mo[r]

As in a past decades, the world today continues to be at crossroads in terms of energy. Shortages and rising prices of fuel, accompanied by environmental damage are leading to a poor quality of life. Fossil fuel consumption is increasing, and our sear[r]

arguable that the increase in CO2 concentration may not be induced byfossil fuel consumption since the carbon cycle is always operating, itcould be due largely to a reduction of the biomass. However, Kraushaarand Ristinen suggested that the net biotic pool of CO2 has not beenmod[r]
