there has been some disputation about whether carbon dioxide, a gas that is so natural, and valuable in our environment, can actually be a pollutant. In 2007, in a case between the state of Massachusetts and the Environmental Protection Agency, or EPA, the supreme court, stated that carbon dioxide did indeed fit the definition of a pollution. An argument I have heard a lot is that carbon dioxide is not toxic, so how could a non-toxic gas be a pollutant. My answer to this is incredibly simple,…

Without any doubt racism is like a still exciting and active Volcano, which can explode any minute without a warning. We know the power of the lava which can destroy people and their homes. A long-lasting problem that is bothering not only our country, but also many individuals all over this planet, is racism. The majority of people may think that racism isn’t a real issue and that it is just a stereotype that certain people are being racist towards black people. Generalized stereotypes are…

As the world population increases day by day, so energy consumption rises also due to the industrial development there are more and more power needs to run these industries and factories. Conventional resources for energy are coal, natural gas, etc. they are form in millions of year so they take long time for their generation so there is need of energy resource that can balance the energy needs and there time of generation. If we take into account the world energy resources then sun would be the…

on a certain volume of fuel or in this case, electrical charge. Electrical cars to date can travel up to 290 miles on a single charge while on the other hand, cars with gasoline engines today can travel over 500 miles on a full tank and refill at a gas station and go again. But because electrical cars are not available on a large scale as…

The Gaia Foundation argues that ‘’contamination of water and ecosystems, disruption of rocks land stability, environment and food production will continue to affect the local people for many of years if the reclamation is not properly done’’ (Gaia Foundation, 2014, p.36). Once the reclamation accomplished, the land is then handle over to the government and the necessary agencies. 2.3 Mining and Health Health is one of the fundamental aspects for the development and survival of all human races…

Consistently the environment is changing and not always for the better. Things we do in regular day to day existence are annihilating our environment. For example, driving automotive vehicles, utilizing power from coal-terminated powerplants, or warming our homes with oil or gaseous petrol, all have terrible and destructive effects on our environment. One of those influences is Global Warming. There are individuals who debate the impacts of Global Warming, yet scientist has demonstrated that…

The ocean circulation can be defined like the global movement of water, which occurs in the ocean basins. These movement of water are the ocean currents, which plays an important role in the climate since store and distribute heat, microorganisms like nutrients and freshwater all over the world. Therefore, any change that modifies the ocean circulation will alter drastically the global climate. In this section it will be broadly explained the factors, which determine the ocean circulation and a…

1. Introduction As we advance in the field of building science and technology, we are increasingly becoming aware of the need for a more sustainable building development. Energy use being the number one contributor to global warming, about 50% of energy is used in buildings, indicating that buildings have a considerable potential for operational energy savings. Climate responsive design provides a comfortable indoor environment in response to the seasonal variations of climate, the direction of…

Climate change refers to the increase in global temperatures. Among the contributors to the rise in temperature is from human activity itself. Warm planets leads and cause the temperature changes and also affect the weather in many ways. Land and sea temperatures are one way to measure the effects of climate change. A global warming has the potential to alter patterns of rain and snowfall, causing severe storms and droughts, reduced ice on the lake, glaciers melts, rising sea levels, and changes…

Crude oil is a complex mixture of various organic compounds, comprising of different hydrocarbons and heteroatomic compounds (Simanzhenkov and Idem, 2003). In addition to carbon and hydrogen, petroleum might contain sulphur, oxygen and nitrogen, and metals such as nickel, vanadium, iron, and copper. Crude oil physical and chemical compositions vary with location, depth and age (Rahimi and Gentzis, 2006). Physical composition of crude oil varies from black liquids of high viscosity to…
