... appears to be so costly at individual, governmental and corporate levels. It appears that great material loss, as well as visual manifestation, have been the only ways to galvanize action towards altering and limiting technologies so that adverse chemicals and substances are no longer belched into the environment. For example, Sagan is right on the mark when he indicates that it took the 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 eff ...

... formed, how it functions, and the effects it has on the universe. By definition, a black hole is a region where matter collapses to infinite density, and where, as a result, the curvature of space-time is extreme. Moreover, the intense gravitational field of the black hole prevents any light or other electromagnetic radiation from escaping. But where lies the “point of no return� at which any matter or energy is doomed to disappear from the visible universe? The black hole's surface is known as the event horizon. Behind this horizon, the inward pull of gravity is overwhelming and no information about ...

... it causes structural changes in the brain, depresses male sperm counts, causes chromosome damage, lowers testosterone levels, and damages the lungs. Most of these claims, however, have been unreplicated in humans or have been contradicted by other work. This section will address each of these reported negative side-effects. Various studies have claimed that cannabis destroys brain cells. However, several other studies found no structural or neurochemical atrophy in the brain at all. Furthermore, it should be noted that Heath's work was sharply criticized for avoiding safeguards of bias and reporting "changes" th ...

... look more like animal factories than animal farms. The farms usually consist of several metal barns, each containing several hundred to several thousand animals tightly confined. The floors in the barns are slatted so manure can be flushed away. The manure is pumped into open-air lagoons, which are large, shallow pits dug into the ground, where it is stored until it can be pumped out to irrigate fields. The solid manure sinks to the bottom of the lagoon and is broken down by anaerobic bacteria over several months. The liquid rises to the top and is collected and sprayed over nearby fields. Many problems come ...

... these estimated 6,000 are felt but cause no damage and about 35 cause minor damage. The remaining 15, however, can take great tolls in death and suffering. When an earthquake occurs, the earth's crust breaks along a surface known as a fault plane. Faults are not always visible at the surface of the earth. A fault is a fracture within a rocky mass within the earth's crust. The depth and the length of faults vary tremendously. Earthquakes are caused by faults that are active. An active fault is a fault along which the two sides of the fracture move with respect to each other. An earthquake is caused by the su ...

... hole(Filkin 202). After being compressed infinitely, almost to nothing, the point in space that it makes is called a singularity(Filkin 216). The singularity is the bottom of the black hole. Every stellar body has an escape velocity(Intro. to Black Holes 1). The escape velocity is the speed at which one must be going to escape the gravity of the object in question(Intro. to Black Holes 1). The Earth’s escape velocity is seven miles per second(Intro. to Black Holes 1). This means that to leave the Earth’s gravitational pull, you must be able to travel at least seven miles per second(Intro. to ...

... means nourishment--"No muscle nourishment." When a muscle has no nourishment, it "Atrophies" or wastes away. "Lateral" identifies the areas in a person's spinal cord where portions of the nerve cells that nourish the muscles are located. As this area degenerates it leads to scarring or hardening ("Sclerosis") in the region. Over 5,000 Americans are diagnosed with ALS each year. There is great variation in the course of the disease. Symptoms usually appear in individuals between the ages of 40-70, though the disease has been reported in both younger and older persons. Survival after the confirming diagnosis is, ...

... restoring balance to mind and body as well as its specific use in treating a wide range of symptoms. Aromatherapy can help ease a wide assortment of ailments; easing aches, pains, and injuries, while relieving the discomforts of many health problems. Aromatherapy also acts on the central nervous system, relieving depression and anxiety, reducing stress, relaxing, uplifting, sedating or stimulating, restoring both physical and emotional well-being. Although Aromatherapy is consider to be a new and alternative foram of medicine in the western world, however it has been practiced for thousands of years in t ...

... French chemist Claude August again isolated it. Thallium comes form the Greek word "thallos". "Thallos" meant "green twig" or "green shoot". Thallium does not have many uses. It is used in photocells because of the electrical conductivity of thallium sulphide. Thallium was originally used to help treat ringworm and many other skin infections. It was then limited because of the narrow margin between the benefits and its health risks. Thallium bromide-iodide crystals are still used as infrared detectors. Thallium sulphate used to be widely used as a pesticide and an ant killer. It was odorless and tasteless and ...

... The Big Bang was the start of time and space. The matter and radiation of that early stage rapidly expanded and cooled. Several million years later, it condensed into galaxies. The universe has continued to expand, and the galaxies have continued moving away from each other ever since. Today the universe is still expanding, as astronomers have observed. The Steady State model says that the universe does not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the ...
