The demands of increasing population magnify demands for natural resources, clean air and water, as well as access to wilderness areas. In the future, when there are not enough resources to go around, we will see significant scarcity, and a backlash of poverty. Left unchecked, the combination of population growth and consumption- along with increasing inequality between rich and poor individuals and nations-will soon threaten not only the well-being, but even the lives of a majority of people on this planet. When population levels reach a critical threshold, we will see both a decline in the resource base, and damage to the environment, which supplies all those resources. These trends reinforce each other - the damaged environment provides fewer resources, and the shortage of resources causes us to further damage the environment. World energy needs are projected to double in the next several decades, but no credible geologist foresees a more...

Being one of the most fatal viruses in the nation, AIDS (Acquired Immunodeficiency Syndrome) is now a serious public health concern in most major countries worldwide. Since 1986 there have been impressive advances in understanding of the AIDS virus, its mechanisms, and its routes of transmission. Even though HIV (Human Immuno deficieny Virus) can be transmitted through sharing of non-sterilized needles and syringes, sexual intercourse, blood transfusion, and through most bodily fluids, it is not transmitted through casual contact or by biting or blood sucking insects. AIDS is defined as a disease, at least moderately predictive of defects in cell-meditated immunity, occurring in a person with no known cause for diminished resistance to that disease. Such diseases include Kaposi's Sarcoma, Pneumocystis carnii pneumonia, and several other opportunistic infections. After the discovery of HIV and the development of HIV-antibody test, the case definition of AIDS was updated to reflect the role more...

Einstein once remarked, "Success is one percent inspiration and ninety-nine percent perspiration. This mantra is often repeated and has been the motto of many desiring such success. 'Yet, in today's world, there have been an increasing number of examples of people who have succeeded without much effort. So then, is hard work still required for success or can it even guarantee success? Judging from evidence present in the world, hard work has never been able to guarantee success but hard work could be needed to ensure success is possible. First, let us look at the idea of success. Success can come in many forms, depending on the individual. Examples include success in one's career, but success is not just limited to the earning of money and power. People can also have a successful family life or successful friendships. An environmental awareness project could be deemed a success, yet the success more...

Cigarette smoking is one of the major killers in the world. The biggest side affect from smoking is cancer. Cancer is a group of many related diseases. All forms of Cancer involve out-of-control growth and spread of abnormal cells. The risk of dying from lung cancer is 22 times higher for males, and 12 times higher for female smokers as oppose to non -smokers. Additionally, smokers are at an increased risk for cancer of the larynx, oral cavity, oesophagus, bladder, kidney and pancreas. Smoking causes a five time increase in the risk of dying from chronic bronchitis and emphysema, and two times increase in deaths from diseases of the heart and coronary arteries. Smoking also increases the risk of stroke by 40-50% in men and 60% in women. Researchers have also proven that mothers who smoke during pregnancy or before they got pregnant usually give birth to babies with birth more...

There are many types of air pollution, one type is acid rain. Scientists have discovered that air pollution from the burning of fossil fuels, mainly in power stations and industry in countries such as Germany, United Kingdom and other economically developed countries, is the major cause of acid rain. Acidic deposition or acid rain as it is commonly known, occurs when emissions of sulphur dioxide  and oxides of nitrogen  react in the atmosphere with water, oxygen and oxidants to form various acidic compounds. Sunlight further accelerates this process with the introduction of heat. These compounds then fall to the earth in either wet form (such as rain, snow, and fog) or dry form (such as gas and particles). There are many effects of acid rain all of which are very negative for the environment. These gases and particles can eat and corrode away the objects which they settle "n, One more...

Asynchronous Transfer Mode (ATM) is a 'high-speed transmission protocol in which data blocks are broken into small cells that are transmitted individually and possibly via different routes in a manner similar to packet-switching technology'. In other words, it is a form of data transmission that allows voice, video and data to be sent along the same network. In the past, voice, video and data were transferred using separate networks: voice traffic over the phone, video over cable networks and data over an Internet work. ATM is a cell- switching and multiplexing technology designed to be a fast, general-purpose transfer mode for multiple services. It is asynchronous because cells are not transferred periodically. Cells are given time slots on demand. What separates ATM is its capability to support multimedia and integrate these services along with data over a signal type of transmission method. The ATM cell is the data unit used more...

In the dictionary, a friend is defined as 'a person whom one knows well and is fond of. A friend is someone who cherishes the special moments and memories of life with another person. A friend is a trustworthy companion. Friendship is a relationship which takes time to build. There are many steps and stages to achieving a true friendship. However, one can think that building a friendship is like planting a garden. Planting a garden needs devotion and leisure. It takes patience to grow a garden. Frustrations and hardships are also involved in the process. Firstly the seed is planted. The seed builds the foundation of a strong and stable plant. It has to be taken care of and watered daily. Then the shoots start sprouting, the plant is finally flourishing. One can see day by day the garden maturing. Then one day the garden starts to wilt, it more...

Few men have ever had as much of an effect in our world as Mohandas Gandhi (1869-1948), as he used the message of peace and love, rather than war and destruction. One time a prominent lawyer in South Africa, Gandhi gave up practicing law and returned to India in order to help ea the suffering of the repressed people of his homeland. Gandhi's love for people and his religious fervour made him a revolutionary in many of his ideas and actions. He desired to see India freed from British rule in a bloodless revolution, similar to the Glorious Revolution of Seventeenth Century England. Knowing that violence only begets violence, he began practising passive resistance, or as he called it, 'Satyagraha' which means holding onto truth In his famous Salt March of 1930, Gandhi and thousands of others marched to a coast where salt lay on the beaches, to protest the more...

Many say that at the current rate of development, we're headed for an environmental disaster. Humans don't exactly hold the best track record for environmental protection and preservation. Throughout time we have exploited nature and its creatures for our own benefit. We have made technological advances that threaten and disrupt the environment with total disregard for that fact. We took slipshod short cuts that are now catching up to us today and we can think of no available alternatives that will remedy the problem quickly and usefully. We have developed a huge and thriving society and in the process we deforest huge sections of land for living and livestock grazing. This decreases oxygen and increases carbon dioxide in the atmosphere possibly adding to global warming though the greenhouse effect.' This massive population produces massive amounts of waste, so to deal with that we just throw it into the ground, which more...
