it can cause irritation and damage the body's immune system (NTSDEC, par 12). That is just a short term effect of burning fossil fuels. Long term effect that burning fossil fuels have even worse effects.Those bad long term effects are caused by the carbon that is released when fossil fuels are burned. As stated by Dr. Richard

be later released to fuel the organisms' activities. And this happen on plants. Photosynthesis can be represented using a chemical equation. The overall balanced equation is... 6CO2 + 6H2O ------> C6H12O6 + 6O2 Sunlight energy Where: CO2 = carbon dioxide H2O = water Light energy is required C6H12O6 = glucose O2 = oxygen As light energy (in the form of photons) reaches a plant, chlorophyll molecules forming a light harvesting complex absorb that energy, exciting electrons. These electrons

Axia College, University of Phoenix [COM 220- 08 March 2009] Have you ever watched a television program, or read an article about Global warming? A person would be hard pressed to find someone who hasn’t. The news is hard to ignore since the information that is given to us comes from scientists or experts in the field of global warming. We are continually bombarded with information that the Earth is experiencing a warming trend, and human activity is to blame. The pollution that man

need to respond to external stimuli, e.g. temperature, oxygen concentration and levels of sunlight. These may be over time, e.g. winter fur to summer fur, or quickly, e.g. changing size of pupils. Internal environments change too- the build up of carbon dioxide as a result of respiration changes the pH of the tissue fluid, and therefore inhibits enzyme activity. Multicellular organisms need to coordinate different organs, so this requires a good communication system which will: • Cover the whole

Change in Uses of Land Increasing carbon storage by using land differently or maintaining carbon storage by avoiding land degradation. • Encouraging the transformation of cropland to forest. • Avoiding the conversion of forest land to settlements. Changes in Land Management Practices Improving management practices on existing land-use types. • Reducing soil erosion to minimize losses in soil carbon storage. • Planting after natural or human-induced forest disturbances

unit of measurement. The values of Americans are polluted by the agendas of politics and entertainment. Subconsciously, the values we hold regarding topics such as Global Warming are intertwined with mass media. For example, we look at Carbon Dioxide and only Carbon dioxide as the villain in global warming. Now, instead of being the subjects of our subconscious, let us delve into our conscious mind and obtain the hard facts that are science. Steven Levitt, in Superfreakonomics details an extremely

essential nutrients from the blood. The body gets rid of waste products, such as carbon dioxide, back into the blood, in order to remove them. The main function of the cardiovascular system is to sustain blood flow across all areas of the body. Veins return used blood (deoxygenated) from the body back to the heart. This blood is low in oxygen as it has been used in the function of the body, and is also high in carbon dioxide (the waste product that the body has gotten rid of). The veins carry this

Year of Forests’. This designation has generated momentum bringing greater attention to the forests worldwide. Forests cover almost a third of the earth’s land surface providing many environmental benefits including a major role in the hydrologic cycle, soil conservation, prevention of climate change and preservation of biodiversity. Forest resources can provide long-term national economic benefits. For example, at least 145 countries of the world are currently involved in wood production. At the

Contribute to Global Warming: this source of energy is not “green” and contains high amount of carbon Non-Renewable: Fossil fuels are a non-renewable energy source. What this means is that there is a limited quantity of fossil fuels that is offered and the energy are not replaced logically; and that fossil fuels are products of masses of years of the regular process like anaerobic breakdown of the carbon-based substance. As divergent to renewable energy foundations such as wind and solar, it can
