ENVIRONMENTAL SCIENCE FINAL PROJECT2Environmental Science Final ProjectMy chosen topic is Energy Conservation. The problem with energy Conservation is that our entire technology-driven society is built on the use of fossil fuels. Fossil Fuels are considered non-renewable resources. It took millions of years or the Earth to form the coal, oil, and natural gas supplies that we’ve been usingfor about the last 160 years. At the rate we’re going, we’re going to run out of energy sources, inanother few hundred years. We’ll have burned through millions of years, worth of resources in about a thousand years, even with careful conservation.All this burning of carbon-based materials generates higher levels of carbon monoxide, and carbon dioxide, as well as adding thick soot to the atmosphere. Carbon Monoxide is poisonous to humans and animals. Carbon dioxide is a greenhouse gas, which traps more solar heat in the atmosphere. The soot particles combine with water vapor in the air, to form smog, which makes breathing difficult and increases the risk of lung diseases and infections. Historically, we’ve seen several instances that clearly indicate the severe health risks associated with this type of pollution. Have a look for yourselves: Historic Air Pollution Disasters. There have been several episodes in history which illustrate the harmful effects of acute short-term exposure to air pollution. Among those include: [Belgium's Meuse Valley. During a five-day fog in December 1930, 63 people died, most of the deaths occurring on the fourth and fifth days. Older persons with previously known diseases of the heart or lungs accounted for the majority offatalities. The signs and symptoms were primarily those caused by a respiratory irritant. They include chest pain, cough, and shortness of breath and irritation of the eyes. Sulfur dioxide gas is suspected as the cause of the disaster.
ENVIRONMENTAL SCIENCE FINAL PROJECT3Donora, Pennsylvania: Twenty people died and approximately 7,000 or 50% of the population, experienced acute illness during the week of Oct. 25, 1948, when temperature inversion and air stagnation occurred. Persons of all ages became ill, but those over 55 were more severely affected. Those with previous heart or respiratory disease, particularly bronchial asthma, suffered most. Symptoms were primarily respiratory and secondarily gastrointestinal, and included cough, sore throat, chest constriction, shortness of breath, eye irritation, nausea and vomiting. The onset of the illness for most persons occurred on the evening of the third day. Of the 20 who died, 14 had some known heart or lung disease. London, England: Three episodes during which heavy fogs and air pollution were associated resulted in the death of nearly 5,000 people - in 1948, 1952 and 1956.The episode in December of 1952 alone, resulted in at least
