.... creeks, marshes, panes, mudflats or mangroves, until what once was land is now water. Throughout the tides, the days and the years, an estuary is cradled between outreaching headlands and is buttressed on its vulnerable seaward side by fingers of sand or mud. Estuaries transform with the tides, the incoming waters seemingly bringing back to life organisms that have sought shelter from their temporary exposure to the non-aquatic world. As the tides decline, organisms return to their protective postures, receding into sediments and adjusting to changing temperatures. The community of li .....

.... reality that CFCs were destroying the sensitive but protective ozone layer to encourage large chemical companies to begin a gradual phase-out of these substances, even when scientists had already discovered the terrible effects of the chemical combination. Sagan says that to slowly stop usage of such obviously dangerous substances is not enough, for even with current conditions, it is estimated that the damaged ozone layer will require at least 100 years to repair itself. In the interim, we are risking danger to the food chain, global warming, and increased cases of skin cancer. Rather th .....

.... other hypotheses concerning UFO's. While all astronomers yearn for a concrete explanation on UFO's, their beliefs on their origin contrast. Many looking for a more scientific definition disregard UFO's as nothing more than a mere misinterpretation of a plane, weather balloon, or meteor. Some have gone so far as to say that specific witnesses to UFO's have seen nothing more than a hallucination and "wanted" to see a UFO so their minds adapted that idea into an illusion to satisfy the urge. Personally, I have had two encounters with unexplainable objects in the sky and to disregard them as .....

.... White for it’s ferocity. It might have also been the size of the shark in the movie that’s kept thousands of people off the beaches and out of the water. Better yet, it could have been the overall storyline: A Great White shark with an eating disorder and a taste for human flesh. Perhaps that’s what is keeping vacationers from grabbing their trousers and snorkels. Over all, there have been 1026 attacks on humans by sharks in the last ten years. Only 294 of these attacks have been linked to Great White sharks. That’s roughly the number of people who drown each year in swimming acc .....

.... most basic requirement of an immune system is to distinguish between one's own cells and "non-self" cells. The second job is to eliminate the non- self cells. When a foreign object enters the body, several things happen. Blood stops flowing, the immunity system begins to eliminate unwanted microbes with phagocytic white blood cells. This defensive mechanism is possessed by all animals with an innate system of immunity. Innate cellular immunity is believed to be the earliest form of immunity. Another form of innate immunity is complement, composed of 30 different proteins of the blood. If t .....

.... year than any other on the planet. Brazilian forests are burned or felled at the rate of 1800 hectares (about 4500 acres) every hour! (Dwyer 39) Deforestation started hundreds of years ago, but only became a major problem in the second half of this century, when it increased dramatically. It was enhanced by the Brazilian government which started cutting down the forest to construct a vast network of highways in an effort to establish a good transportation system and improve Brazil's economy. The government wanted to encourage the country's development by transporting poor families from .....

.... issues today. In Roswell, New Mexico, 1947, a strange occurrence arises. An alien craft from outer space crashed in an open field. The issue lay still for almost thirty years, until the thought of a government cover-up arose. Society's opinions have changed over the years. Previous to the 1990's, people have despised the thought of sharing the universe with other intelligent life forms. Now people are interested in this mysterious phenomenon. People think it is the blame of the movies and television. By watching this, people are at a level at which they understand. Not only do .....

.... blood pressure. Result shows that those with normal blood pressure experience no change at all when placed in a extremely low salt diet, or later when salt was introduced, Of the hypertensive subjects, half of those on the low salt diet did experience a drop in blood pressure, which returned to its previous leel when salt was introduced. Of course, these are other researcherswhgich tend to support the findings. A small Indiana study showed that when normal individuals took large amount of salt, the bolld pressure did not consistenly rise into the hypertensive range. Also, study i .....

.... same time not allowing their customers to use complementary treatments such as chiropractic to prevent or cure illness. The more rigid and restrictive the policy provisos, the more assurance for the companies that they will maximize their bottom lines. Therefore, patients of alternative therapies as well as doctors must show that such unconventional treatment provides relief and prevention of illness. “The total projected out-of- pocket expenditure for unconventional therapy plus supplements(such as diet pills and megavitamins)was 10.3 billion dollars in 1990. This is comparabl .....
