Environmental Issues

One of the biggest disasters that hit the world in the first decade of the 21st century was the terrorists attack on the World Trade Centre twin towers and the pentagon on September 11, 2001. This incident was horribly devastating to the people and national pride of the United States and it left so many people around the world shocked and dumbfounded. It raised fundamental questions on national security of magnitude not seen before in the United States. The attack was a series of co-coordinated...

Human Impact on the Sea The ocean has been one of the most resourceful of all the natural resources man has ever encountered. But in the last couple of centuries human impact on the sea has been enormous and has led to other chain of changes, some of them may prove to be disastrous for the mankind. This paper will discuss the human impacts on the sea in the light of  The Economist  series articles. The resources of the sea are always considered unending, whether it is the food supply...

Home heating and cooling Passive solar heating and cooling technique, which are environmental friendly and cost effective also are used. Propane furnaces, propane water heaters , oil furnaces and solar water heaters are the reliable and energy efficient home heating and cooling systems. Electric generation Coal is used as the major source of generation of electricity in Michigan. Wind energy is also utilized in generating electricity as an efficient renewable source of energy. Nuclear  energy...

Our environment is either clean or littered. With a clean environment, it implies that either the people living in this environment do not litter or if they do, there is a section of the society that takes the responsibility of removing the litter. On the other hand, there are people who throw rubbish irresponsibly littering the environment. These two groups of people differ significantly in terms of their attitudes, personality and backgrounds. People who litter often lack a sense of personal responsibility,...

A change in the distribution of weather within periods of time that could be millions of years or even just decades is referred to as climate change.  It can be a greater or lesser change in weather and its events with either more or less events of weather occurring.  It may be restricted to a particular area or even distributed across the entire globe.  There are a number of factors that can shape or cause climate change and they are called climate forcings (Burroughs). One of...

The current paper discusses the role of renewable energy sources in the context of the current energy consumption. Solar and wind energy, hydropower, and biomass are included into the list of the basic renewable energy sources. The paper shows that the environmental effects of renewable energy can be readily reinforced through energy conservation. The example of Missouri Electric Cooperatives is used to show how renewable energy initiatives are being promoted at the state level. Renewable Energy...

In simple terms, atmospheric pressure is the weight of air at any given point on earth. It is affected by elevation and temperature (Tarbuck and Lutgens, 2004). At higher locations, the pull of gravity is weaker hence the air is less dense and lighter. Towards the center of the earth, atmospheric pressure increases because of the growing pull of gravity. Temperature also affects atmospheric pressure. Air molecules expand when heated, therefore there is less air per unit volume at higher temperatures....

Every hour or every minute of the day we consume a particular amount of energy. Whenever we use our cellular phones or computers to communicate with our friends, or go to the mall for a shopping spree we use energy. Almost everything that gives us comfort, protection, safety, and satisfaction, such as car, air-conditioning unit, laptop, printer, heater, etc. breathes and consumes energy. Innovative technology and new inventions improve our lives and provide us the necessary comfort and protection....

For a period of five decades or more, global players in international food security have tried to convince the world that the only way that humanity can sustainably be fed is by practicing large-scale or industrial agriculture and the use of herbicides and pesticides. During the 1940s, a movement referred to as the Green Movement was established towards this cause. According to St. Peter, The Green Revolution that began in the 1940s promised that advanced technologies in machinery, seeds and chemicals...
