... 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 of the direct effects of acid rain is on lakes and the whole aquatic ecosystems. There are several ways the acidic ...

... is why it should be stopped. Since its discovery, 30% of Brazil's rain forests have disappeared, and the country is still losing more rain forest each 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 wante ...

... and future. Many people go through guilt, crying, or having suicidal thoughts. Unlike a manic episode, the person has lack of energy, and either an appetite loss or gain. Manic depression is a recurrent illness, so a person usually has more than one episode. These episodes can last from weeks to months. They occur whenever and have no certain pattern. Sometimes a stressful life event can trigger an episode, and sometimes they just happen. If a person has more than four episodes a year they are known as “rapid cyclers”. This is more common in women. There is no exact reason for what causes manic depression, but some doctors say that it may be from imbalanc ...

... mutation and a new understanding of genes and DNA, the evidence supporting evolution has greatly increased. Charles Darwin was one scientist who helped to increase the evidence supporting evolution. Darwin developed the idea of “natural selection” where living things that reproduced in large numbers and survived became dominant and other living things adapted to survive, or they died. Francis Crick, a scientist, co-discovered DNA which opened new doors to the idea of evolutionism (History). DNA is the pattern by which people are created as individuals. Now Evolutionism is the only origin of life that can be taught in public schools. However, in pr ...

... cloning is basically an extension of current and accepted prac tices. Also, the general public's fear shows up in the nation's congress and even the president. Who knows the real opinions of the individuals in congress, but as long as the general public is against cloning, politicians will be too, so they can gain support from voters. Even with all these setbacks, there are still major uses for cloning research. Uses that will never present themselves unless people put down their moral, ethical, and religious shields and allow the research to take its course. Regardless of the majority opinion, cloning is just another science. It deserves the time and mi ...

... UFO sightings first started in the late 1800s, but there weren't that many until the 1940s. In the 1940s UFO sightings were being told all over the world. Since the 1940s UFOs are seen every day by people all over the world. Ufologists have come up with a system to divide UFO incidents into three major types of close encounters. First, close encounter of the first kind (CEI) are classified as UFO sightings. Second, close encounters of the second kind (CE2) are sightings and permanent evidence, such as marks in the ground or burns on grass. Third, close encounters of the third kind (CE3) are actual contact with alien beings from a UFO. (Oberg 240) There are ...

... to take place in order to release latent heat and it is the latent heat that initiates the development of the storm and consequently produces heavy rainfall. When the hurricane reaches its maturity an eye develops in the centre, in the eye there is a relative area of subsiding pressure. Which is what causes clear skies, anomalous high temperatures and light winds. Eventually the eye disappears as a result of the descending air increasing instability, which in turn warms and increases the storms intensity. Around the eye there are towering Cumulo-nimbus clouds. The hurricanes decline as soon as the source of heat is lost/or removed. Although it can take bet ...
