... are not fully developed. Asthma is more likely to develop with children who breathe secondhand smoke (www.alaw.org). It can also exacerbate frequent attacks. Babies are three times more likely to die form Sudden Infant Death Syndrome (SIDS) if their mothers smoke during pregnancy. Ear infection, coughs, sore throat and even cancer can also develop if children are expose to secondhand smoke. With all these harmful to children, there are ways to protect them from it. First, as a parent, don’t smoke. If you are a smoker, quit! If you can’t, don’t smoke in your house, in the car or near your children. Have a permanent place outside the house just for smoking purpose ...

... have two facets or parts: it is a major source of man-made repercussions as well as being the basis of life support systems. Therefore, we are between two sections in which one is the section of "resource availability and waste", and the other "the continuity of life support systems pertinent to survival." Thus, the environmentalists believe that nuclear energy should not be used for various reasons. First of all, the waste product, i.e. plutonium, is extremely radioactive, which may cause the people who are working or living in or around the area of storage or use, to acquire leukemia and other cancers. They also show how billions of dollars are spent year ...

... Methyl Tertiary Butyl Ether (MTBE) be a required ingredient in gasoline formulas with the goal of increasing combustion efficiency. A fuel oxygenate, MTBE enhances the octane in gasoline and decreases carbon monoxide emission by increasing burning efficiencies. In its haste to declare MTBE as a required ingredient in gasoline, the EPA failed to consider a basic chemical property of MTBE and its long-term effects upon the environment. Because MTBE is highly water-soluble, it dissolves in water, leading to higher concentrations of MTBE in many lakes in the California Sierra Nevada mountains and in many groundwater supplies. Hence, by addressing only one component of ...

... without creating an unmanageable deluge of information. Computer simulations of landscapes provide useful models for gaining new insights into the coexistence of species. Although many ecologists have found fractal geometry to be an extremely useful tool, not all concur. With all the new insights gained through the appropriate application of fractal geometry to natural sciences, it is clear that fractal geometry a useful and valid tool. New insight into the natural world is just one of the results of the increasing popularity and use of fractal geometry in the last decade. What are fractals and what are they good for? Scientists in a variety of disciplines have be ...

... it is these substances - very beneficial from the economic and production aspects of farming - which can pose risks to human health and the environment if not properly used. Pest problems are not new; in fact, they have been around as long as agriculture itself. But the pest pressure faced by farmers is now as great as it ever was: the world's fast-growing human population needs to be fed from an always shrinking base of agricultural land, and the substantial damage that can be inflicted by pests (e.g. insects, diseases, weeds, rodents, birds) on crops is the margin between a good harvest and a bad one. Pests can reduce the quality of a harvest as well as its qua ...

... do in some form or another. This took a lot of time researching, as there are so many to choose from. I also wasn't real sure of where to begin. I decided to begin with location and money, which are important when deciding a college. Next I decided to visit the few I singled out which greatly helped me choose this for my education. Next I had to perform and even harder task, choosing a major. It's very difficult to decide what you want to do with the rest of your life in just a short time. I had the plans of working in the woods, so I talked with some friends who work with wildlife conservation and they told me parks and recreation was the way to go. After t ...

... understanding development of wind shear below the bases of convective clouds is a good knowledge of the characteristics of a typical precipitation-induced downdraft. Not all precipitation-induced downdrafts are associated with critical wind shears. However, there are two types of down drafts that are particularly hazardous to flight operations because of there severity and small size. Professor T. Fulita, an atmospheric scientist from the University of Chicago, coined the term downburst for a concentrated, sever downdraft that induces an outward burst of damaging winds at the ground. He also introduced the term microburst for a downburst with horizontal dimensions o ...

... not about the tiny blood vessels that you can easily see on the surface of the eye. It's to do with the larger vessels All I had to do was take a person into a dark room with my flashlight. I had them cover their left eye and look down at the floor with their right eye. I held the flashlight up towards the ceiling under their right eye, but they kept looking at the floor, not the light. RESULTS I am writing down what everyone recorded for me. I am first: JOSH: I could see black blood vessels with orange in the background...it looked like a lot of dead tree. BRENDA: The blood vessels resembled jagged lighting bolts or trees in the winter time. LAURA: I saw ...

... and a change in the person’s voice. If the tumor occurs in the supraglottis, or the section above the vocal cords, it may cause a lump in the throat, sore throat, or earaches. When the tumor develops in the area where the larynx and trachea join, subglottis, the person experiences trouble in breathing, very noisy breathing. Constant coughing or a feeling of a lump that doesn’t go away are also signs of larynx cancer. Tumor development in the subglottis is very unusual and rare. As a tumor grows it may cause pain, weight loss, bad breath, frequent choking on food, and hard swallowing. Only qualified doctors are able to tell if any of the si ...

... bronchitis; blocking of stomata, reducing CO2 absorption; erosion of limestone and sandstone buildings; increased susceptibility to respiratory infections; throat and eye irritation; leaf necrosis, reduced growth and growth abnormalities and drowsiness. Increasing levels of air pollution, particularly particulates from vehicles, are linked to increasing respiratory problems including asthma and this air pollution is thought to cause up to several thousand deaths and up to 20,000 hospital admissions every year. Acid rain is another serious problem, helped along with the increased usage of motor cars. The increased acidity of the precipitation is down to contamination ...
