.... are that the planet Earth's water resources are depleted now. How can we allow the population to grow unchecked, when we know that even now, the Earth's water supplies are taxed to the limit? The subject of over-population encompasses many areas of study. Some examples are health, food, pollution and fresh water. The underlying link between all of these areas is water. The following four articles reveal that the water supplies that we all depend on are being used at an unsustainable rate. There is not enough fresh water on this planet for current growth rates to continue. The Public Broadcasting Company has posted on the Internet a timeline detaili .....

.... (Hodges 526). Smog has been a problem in coal-burning areas for several centuries. Smog finally decreased when coal combustion was replaced by oil and gas combustion. Air pollution is caused by a number of different types of pollutants. The first type, particulate matter, consists of solid and liquid aerosols suspended in the atmosphere. These arise from the burning of coal and from industrial processes. Atmospheric particles can scatter and absorb sunlight which reduces visibility. Particles also reduce visibility by attenuating the light from objects and illuminating the air causing the contrast between the objects and their backgrounds to .....

.... settle in the auditory cortex, and memories of its appearance into the visual cortex. Its here in the limbic system they assemble all these memories, gathering them into a cohesive whole. False memories are also commonly in the con drum called "source amnesia". Thanks to the brain's frontal lobes, most people can distinguish the memory of a dream and a real life event. But if the frontal lobes are damaged, people cannot remember where a memory came from. These people retrieve bits of memory and can't remember where they came from and could be remembering a dream. Source memory is highly prone to suggestion and if you imagine it enough and us .....

.... is a bad thing, then I’m sorry. People often question whether or not we have the right to clone. We are all guaranteed rights by the fact that we are human beings. Those rights include the right to pursue areas of scientific study, and also the right to live. They could have argued the fact that man was not meant to walk on the moon. If they did, and the program did not succeed, then we would not have the technology that we have today. Cloning organs can only yield new technologies that will be beneficial to society. Organ cloning is something that would be extremely beneficial to society. Imagine the ability to "create" a liver for James Earl Ra .....

.... or syringes with. AIDS and HIV are two different viruses, but HIV well eventually turn into AIDS. About half the people with HIV develop AIDS within 10 years, but between infection with HIV, the onset for AIDS can vary greatly. The severity of the HIV related illness or illnesses will differ from person to person, according many factors but mostly to the overall health of the individual. The new advances in technology are helping postpone the advancement of the disease. Lets start at the beginning. First, lets learn what AIDS is. AIDS is an acquired defect in your immune system. The passing of any bodily fluids could technically be used as .....

.... feet high traveling hundreds of miles per hour. It would start to slow down crashing ashore through all coastal city. Then, finally wash up hundreds for miles inland. " The mid-Atlantic Ocean impact ranging from 400 meters to 5 kilometers in diameter. This would generate a tsunami that would sweep across the upper East Coast of the United States to the Appalachian Mountains."(Gottschalk 1) The blast of the impact would equal a 300 gigaton blast of T.N.T. Also, 2.4 seconds after impact, a small fireball with a temperature of 5000'C would sweep across long island. A land fall strike would cause total divistation. The asteroid would create a earth tre .....

.... of women in the first trimester of pregnancy. There are many aspects that have to taken care of when an ectopic pregnancy is identified. Not only are there the symptoms, the diagnosis, the treatments, and the results to deal with, but also moral ethics come into play. The term “ectopic� literally means “out of place�. Other things in the human body can also be considered ectopic if it sits in an abnormal position in the body. A heart beat that originates from and unusual part of the heart is an “ectopic� heart beat, and a baby that is not properly nestled in the uterine cavity is an “ectopic� pregnancy. In an ectopic pregnancy the b .....

.... experiment with the pop can is that the can will crush because of a drastic change in temperature. 2) the experiment with the milk jug and the hot water is that the milk jug will remain the same. 3) the experiment with the egg and the bottle is that the egg will not be sucked in the bottle. PROCEDURE: For the first experiment the procedure is: 1) Heat an ordinary pop can on a hot plate. 2) After about fifteen minutes take the can off the hot plate and put it upside-down in a pan of cold water. 3) Record my observations on a piece of paper. 4) Write my conclusions in my science fair logbook. For the second experiment my procedure is .....

.... the islet cells. If the human version of the same gene could be turned on in similar fashion, type I insulin dependent diabetics and type II's who inject insulin might have their natural insulin-producing apparatus restored. What is Diabetes? Well, this disease is known as "diabetes mellitus," diabetes from the Greek word meaning excessive urination, a symptom the Greeks noticed, and mellitus, from the Latin for honey, which is because diabetic urine is filled with sugar and is sweet. Physicians and medical books use the term diabetes mellitus, but is the most commonly called diabetes. There are two major types of diabetes: type 1 and type 2. .....

.... fumes. Like sulphur dioxide, the nitrogen oxides rise into the atmosphere and are oxidized in clouds to form nitric acid. One of the most serious impacts of acid precipitation is on forests and soils. A lot of damages are being done when the sulphuric acid falls onto the earth as rain. All the nutrients in the soils are washed away making it hard for some plants to grow. The presence of nitrogen oxide and nitric oxide also can force trees to grow even though they do not have the necessary nutrients. The trees are sometimes forced to grow during late autumn when it is actually the time for them to prepare for severe winter weather. One .....
