Algae can be used to harness the carbon dioxide, nitrogen, make oxygen and be refined for biofuel.Cyanobacteria is the most common type of microalgae used for biofuel (“Massachusetts company making,” 2011) The biofuel from algae can be cost effective, only costing ten to twenty dollars a barrel to produce....This observation has been an issue of major environmental concern in the view of the potentially devastating effects of climate change on ecosystems and human survival.Recent studies by scientists led by Wei-Jun Cai have served to underscore this fact by showing that the Arctic region and the globe are faced with a major climate challenge due to the continued melting of sea ice in the Arctic Ocean....As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago....[tags: greenhouse gases, climate change, global warming] - Since the industrial revolution, scientists have documented a trend of increasing atmospheric carbon dioxide (CO2), the main greenhouse gas.Although it is known that greenhouse gases are necessary for the survival on earth, without these greenhouse gases such as carbon dioxide the earth would be lifeless.However, we still have to deal with anthropogenic causes which drastically intensified the greenhouse effects in the atmosphere.
Highly polluted areas, such as the Los Angeles area, pose a threat to the elderly, children, and people suffering with COPD (Chronic Obstructive Pulmonary Disease) (“People at Risk,” 2013).
Coal and natural gas fueled electricity generation in 2011 accounted for 80% and 19% of CO2 emissions in the U. Many researchers are now greatly interested in incorporating environmental factors when discussing growth, industrialisation, and trade for reasons that in the end, boils down to the wanting of environmentally sustainable economic growth.
Numerous studies were already conducted all around the world to determine the effect of macroeconomic variables to carbon dioxide emissions....
Sunlight easily passes these gases on it way into the earth’s atmosphere but on its way out the gases reflect the radiation back towards earth....
