Acid Rain
Acid Rain Acid rain forms when sulfur and nitrogen dioxides combine with moisture in the atmosphere to produce rain, snow, or another kind of precipitation. This kind of pollution may also be suspended in fog or deposited in a dry form. Acid rain is most common in North America and Europe. Acid rain has also been detected in other areas of the world such as tropical rain forests of Africa. Canada has placed limitations on the sulfur emissions. The United States has not, so the emissions may stil

An Ecosystem's Disturbance by a Pollutant Paul Cordova L.

Destiny: the seemingly inevitable succession of events.1 Is this definition true, or do we, as people in real life or characters in novels, control our own destiny? Gustave Flaubert’s Madame Bovary exemplifies how we hold destiny in our own hands, molding it with the actions we take and the choices we make. Flaubert uses Emma Bovary, the main character of his novel, to demonstrate this. Throughout her life, Emma makes many decisions, each one of them affecting her fate and by analyzing these de

William Faulkner Life is fickle and most people will be a victim of circumstance and the times. Some people choose not to let circumstance rule them and, as they say, time waits for no man . Faulkner’s Emily did not have the individual confidence, or maybe self-esteem and self-worth, to believe that she could stand alone and succeed at life especially in the face of changing times. She had always been ruled by, and depended on, men to protect, defend and act for her. From her Father, through the

Chemical warfare is the use of natural and man-made toxic substances to incapacitate or kill an enemy. There are many different types of agents used in chemical warfare, some of which are mustard gases, nerve gases, psychotomimetic agents, tear gases, hydrogen cyanide, and arsines. All of which are very poisonous and lethal when exposed to humans in large amounts. Until the 20th century such warfare was primarily limited to starting fires, poisoning wells, distributing smallpox-infected article

Ernest Hemingway once gave some advice to his fellow writer F. Scott Fitzgerald. If something in life hurts you, he said, you should use it in your writing. In A Farewell to Arms Hemingway followed his own advice.

The first of these experiences was a physical hurt that occurred on July 8, 1918. On this date, two weeks shy of his nineteenth birthday, H

This conclusion has been arrived upon from the study of concrete scientific evidence by way of the study of acid rain and its effects on the environment. Acid rain hurts both lakes and other bodies of water as well as vegetation. Many bodies of water are extremely sensitive to acid rain because they do not have the ability to neutralize it. Such
