Wind Power Generation is green and does not release harmful carbon dioxide or other pollutants. One of the most economical forms of alternate energy today is wind energy. The energy captured by these wind turbines is in fact renewable and a great way to add to solar systems if you have them. Small wind turbines may be one of the lowest cost, and source, of clean electricity for rural America. People have been using them in rural areas for household electricity for many years and in the past...
M. King Hubbert, in Resources and Man said, "It is evident that the fortunes of the world's human population, for better or for worse, are inextricably interrelated with the use that is made of energy resources." Energy is a major input for accelerating the growth pattern of a nation. As in the case of fortunes, sources of non-renewable energy are limited. No community focusing on development can compromise on its energy requirement. Thus the availability and access to the energy...
As clarified in the introductory part of this study, Solid Waste Management is defined as the collection, transportation, processing or treatment, recycling or disposal and finally monitoring of waste materials. The term is usually related to the materials produced by various activities undertaken by humans and is generally carried out to reduce their negative effects on their health, environment and aesthetics. Waste management is also undertaken to recover resources for further commercial or...
In recent decades, lack of recycling of drink containers has become a very real problem for the United States. As the population grows, more demands are being placed on our natural resources, including landfill space. Voluntary recycling programs have been only partially successful in keeping drink containers out of landfills. While some countries outside of the US have instituted stronger measures, the US has lagged behind in mandatory recycling. This paper will be an outline of two of the...
The mild combustion is known as a combustion process that has highly combustion efficiencies with minimization of pollutant emissions. In this review, the definition, characteristic and introduction of mild combustion are elaborated and then the factor causing the reductions of NOx by mild combustion from the numerical and experiments done are collected. In the recent year, there is numerous finding about how to reduce the pollution cause by a combustion process. The usage of catalytic...
The forest is a complex ecosystem consisting mainly of trees that buffer the earth and support a multitude of life forms. Numerous ecological functions are carried out by the forest. Therefore one must be careful in the managing and conserving of the forest. Trees can create environment which in turn affect the kind of animals and plants that can exist in the forest. However the most important role trees carry out is the purification of air. Trees are capable of replenishing supplies of oxygen...
Climate change is a serious issue that needs to be dealt with, if Americans do not act immediately the consequences are likely to be catastrophic. In the early 1800's Jean-Pierre Perraudin described how glaciers may be responsible for the boulders witnessed in the Alpine Valleys. His radical idea at the time was seen as extremely extraordinary and many scientist and scholars disbelieved his theory. However as word spread about this theory a well known scientist named Louis Agassiz discovered...
Earths surface consists of 70 oceans. The oceans enclose roughly 97 of the Earth's water supply. They produce more than half of the oxygen in the atmosphere, and absorb the most carbon from it (Laffoly, 2009). The air that we breathe, the water we drink, the food we eat, the products that keep us warm, safe, informed, and entertained -all can come from or be transported by the ocean (Laffoly, 2009). Estimated, half of the world's population lives within the coastal zone, and ocean-based...
The 1987 Philippine Constitution lays down the basic framework for our policy on the environment. It states that "The State shall protect and advance the right of the people to a balanced and healthful ecology in accord with the rhythm and harmony of the nature. It further mandates the State "to protect and promote people's right to health. DENR is the primary government agency responsible for the conservation, management, development and proper use of the country's environment and...
Forests act as an important part of the global carbon cycle (Dixon et al., 1994) as they store a large part of the total terrestrial organic carbon in both trees and soils (Brown et al., 1999). During photosynthesis forest absorbs carbon dioxide (CO2) and stores it as plant biomass, which provides a natural stock of carbon. Forests also exchange CO2 with the atmosphere. Although forest ecosystems cover only 30% of the land area they contain 81% of the Earth's terrestrial carbon biomass (Dupouey...
