... by humanity. Rather, its principle aim is, as of any other technology, to improve the quality of life for the people of this planet. Therefore, it is necessary to weigh the benefits and consequences of this relatively recent breakthrough and determine in which ways it can be used to humanity's best advantage. This speech will investigate the ways in which genetic engineering affects two important areas in today's society. The first one will be the improvement of the world's agricultural techniques. With an ever-increasing growth in world population, the Earth's resources are constantly becoming scarce. The advent of genetic engineering may be used to avert the ...

... difficulty and cost of properly disposing of these products they are often emitted into the atmosphere with little or no treatment. The term was first considered to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century mos ...

... layers in the ice core correspond to times in the more distant past. The air bubbles can be analysed for the relative abundance of carbon dioxide to estimate atmospheric carbon dioxide levels at times extending back 160 000 years. Through the ice sheet, we know that 160 000 years ago, carbon dioxide concentrations were about 180 ppm and have presently exceeded 350 ppm. 5) There are mainly 3 major sources of carbon dioxide presently and historically. They are industrial activity, land use change and cement plants. The carbon dioxide from industrial activity mainly comes from fossil fuel burning and is by far the most abundant of sources. The carbon dioxide ...

... gamma photons are produced. Today's theories of the universe say that there is no such thing as a negative mass. The second and more subtle mistake is the idea that anti-water would only annihilate with ordinary water, and could safety be kept in (say) an iron container. This is not so: it is the subatomic particles that react so destructively, and their arrangement makes no difference. Scientists at CERN in Geneva are working on a device called the LEAR (low energy anti-proton ring) in an attempt to slow the velocity of the anti-protons to a billionth of their normal speeds. The slowing of the anti-protons an ...

... and the other for sustaining flight. The idea of using an airscrew for propulsion was utilized during the late 1700's to early 1800's. Only after experimentation did the inventors conclude that more propulsive power could be obtained by merely straightening out the surface of the airscrew blades. Attempts to utilize the "straight blade" propeller were made by balloonists. These contraptions were quite strange and hardly fulfilled their purpose of actually propelling the balloon. The basic propeller had evolved from the simple concepts of da Vinci, and was slowly becoming an effective means of aerial propulsion. To reach the next plateau of flight an increased kno ...

... long and found trace elements of a big mumbo jumbo word— polycyclic aromatic hydrocarbons. That pretty much means that there once was a warmer climate and maybe even lakes or oceans. Life on Mars is now a real idea. The climate of Mars about 3.8 billion years ago was much similar to the young Earth. Microbes and bacteria probably sprouted everywhere in the warm and wet climate. Although now we only see a cold red planet, which was probably due to a collision of an astroid that would have set back the evolution process of Mars, causing it to be a harsh planet. A Viking spacecraft which landed on Mars in 1976 found that the planet was bathed in ultraviolet radia ...

... burned through bitterbrush and light woody debris, mimicking the natural understory fires of old and thus protecting a stand of mature ponderosas. The fire was moving ionals throughout the U.S. In other words, the present emerging technology is a lot more parochial (meaning practical) than political - a refreshing thought. "Honey, your fire has escaped.!" "There's no guarantee you'll not get a big rip," (see terminology sidebar, page 57) says a Forest Service fire officer on the eastern seaboard. "When you're messing with fire, there's always a chance one will escape," echoes his counterpart in California's Sierras. "The fuels are tricky..." adds Ron Meyers, who di ...

... The sheet flood flows proposed for this area by Shaw et al were about 150 km wide, and the total volume of the meltwater reservoir was estimated as about 84,000 km3. The subglacial flood hypothesis for drumlin origin has been applied to drumlins in New York, southern Ontario, the northeast shore of Georgian Bay in Ontario, and to the interpretation of hummocky terrain in southern Alberta, and other areas, by various workers. Shaw suggested as many as 10 meltwater discharges, similar to those which caused the Livingstone Lake drumlins, would be needed to account for drumlin fields in other areas [Shoemaker, 1995, p. 3]. The subglacial meltwater hypothesis of Shaw ...

... are five classes of types of genetic engineering, agricultural treatment, somatic gene therapy, germline cell therapy, medical treatment, and eugenic therapy. Many people believe that genetic therapy is morally not right, but there are so many benefits for the world because of it. Some of scientist ideals of how to alter this new science to create the perfect human does in-fact sound crazy. But if genetic engineering was regulated to prevent such things the new science could bring wonders to many peoples lives. The first form of genetic engineering began with a man named Mendel, a monk in the late nineteenth century. He was the first to even formulate the conce ...

... constant nuclear fusion reaction that is taking place. The amount of energy at the solar constant, which is at outer edge of the earth's atmosphere, is two calories per minute per cm squared. A calorie is the amount of energy needed to raise one gram of water one degree Celsius. If we could efficiently harness the energy bombarding the earth for twenty-four hours we could power New York for a year. Unfortunately the photovoltaic cells that change the energy into electricity are so inefficient that it would take twenty-five years to pay for it's self in output. There many uses of solar energy. Some homes rely fully on the power of the sun to heat their water. Oth ...
