The problem of the ice melting The melting of polar ice is primarily caused by the increasing amount of gas emissions‚ mainly CO2 rising into the atmosphere (global warming) Global warming is the rise in the average temperature of Earth ’s atmosphere and oceans. Since the early 20th century‚ Earth ’s mean surface temperature has increased by about 0.8 °C. Scientists are more than 90% sure that it is caused by rising amount of concentrations of greenhouse gases‚ which are produced by human activities

ETHANOL (E85): Types of fuels are ethanol‚ natural gas‚ diesel and hydrogen. Ethanol is simply grain alcohol obtained from corn. The corn is ground to powder form and mixed into a mash that is distilled to obtain ethanol which is a flammable liquid and then used as fuel. The ethanol could be mixed with gasoline blend in order to obtain reduced cost. In addition‚ the emission of Co2 would be reduced‚ but not completely eradicated because of its content of 90 percent gasoline and 10 percent ethanol

“Modern Technology has improved our quality of life” Modern technology is the use of machines etc to improve our standards of living such as non-materialistic qualities of life (healthcare‚ education etc) or materialistic qualities of life such as the use of smartphones etc. Modern technology has greatly improved our quality of life through the invention of medical technology to provide better and cleaner healthcare services such as the defibrillator and the X-Ray machine. Both the defibrillator

During the process of photosynthesis‚ trees take in carbon dioxide and produce the oxygen we breathe. According to the U.S. Department of Agriculture‚ "One acre of forest absorbs six tons of carbon dioxide and puts out four tons of oxygen. This is enough to meet the annual needs of 18 people." Trees‚ shrubs and turf also filter air by removing dust and absorbing other pollutants like carbon monoxide‚ sulfur dioxide and nitrogen dioxide. After trees intercept unhealthy particles‚ rain washes them

Environmental Sustainability Paper GLG/101 Danita LaSage Rachelle Ann Franko September 10‚ 2011 In today’s world it’s our responsibility as the population to create Sustainability with the earth’s resources. There are only so many resources on earth like timber‚ food‚ petroleum etc. to go around. The more that we use and take in the less it becomes available for us to consume. The world’s budget cannot indeterminately increase on a limited world. As a result the economy develops and the population

warming is the heating of the earth caused by the “greenhouse effect”. The greenhouse effect is the warming that happens when certain gases in the earth’s atmosphere trap heat. Some of these gases occur in nature. For example‚ water vapor‚ carbon-dioxide‚ and methane. Other gases are solely human-made such as the gases emitted from industrial factories. These gases let in light but keep heat from breaking out‚ like the glass walls of a greenhouse. First‚ sunlight radiates onto the surface of the earth

and more rapidly occurring than others do‚ the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels‚ land clearing‚ agriculture‚ and other human activities‚ are believed to be the primary sources of the global warming that has occurred over the past 50 years.

usually through precipitation; this process disrupts ecosystem nutrient flows and may kill freshwater fish and plants dependent on more neutral or alkaline conditions (see acid rain). Acid rain - characterized as containing harmful levels of sulfur dioxide or nitrogen oxide; acid rain is damaging and potentially deadly to the earth’s fragile ecosystems; acidity is measured using the pH scale where 7 is neutral‚ values greater than 7 are considered alkaline‚ and values below 5.6 are considered acid
