| Acid Rain | .PrinceEcologyApril 3O, 2013 | | | Abstract Acid Rain is a mixture of wet deposition and dry deposition. Acid Rain is caused by a surplus of the chemicals sulfur dioxide and nitric oxide caused by air pollution. Air pollution comes from two main sources man made sources and natural sources. Man made sources come from combustion of coal used in power plants and exhaust pipes and natural

The Long- Term Effects of oil on ecosystems: A comparison of the Exxon Valdez and the BP oil spill The Exxon Valdez was a single hull, 987-foot super tanker built by the National Steel and Shipbuilding Company, out of San Diego, California. The Exxon Corporation commissioned this ship into service on December 11, 1986. After the March of 1989 collision with Bligh Reef, the vessel was towed to the shipyard in San Diego and repaired in June of 1989, more than 1,600 tons of steel needed

maintained a unique combination of chemicals. Absorbing the natural emissions from volcanic action and the life cycle, balancing the chemical composition providing a life sustaining biome. The atmosphere provides both life and protection to the ecosystems on the planet from the sun’s UV rays and a variety of debris from space. The atmosphere acts as a blanket working in a layering system to

Management of water quality addresses the problems that are related to water quality and water valuable uses. The control on water pollution depends on adequate treatment and elimination of wastewater (Krenkel at el, 1980). Goel (2006) refers to pollutant water giving a broader definition depending on the physical and chemical properties and biological characteristics causing harmful effects on human life according to required uses of water. Goel (2006) mentions the changes that occur in the natural

have finished going through extensive restoration, with techniques such as solarization and re-introduction of native species. Most of the ecosystems are now returned to their pre-disturbed state, but continued efforts are needed to preserve the locations. 1.0 Introduction: The term “ecological restoration” is generally defined as “the return of an ecosystem to a close approximation of its condition prior to disturbance” (NRC Report, 1992). Although this term is often oversimplified, it includes

What Water is Worth We Need Clean Water to Survive Thomas Fuller, an English author, once wrote, “We never know the worth of water till the well is dry.” Humans are not the only organisms dependent on water for survival. Plants, animals, and the entire planet Earth are dependent on water. The Earth is made up mostly of water, but only three percent of that water can be considered fresh enough for human consumption. With only three percent of the Earth’s water able to be consumed, it is imperative

of treatment, such as chemical precipitation, do not provide sustainable solutions as the pollutants are merely transferred from the waste water to a sludge residue which is disposed of by land-filling. The pollutants eventually find their way to freshwater supplies thereby contaminating it. Water hyacinth is a noxious weed that has a rapid growth rate and easily congests the water ways in Lagos, a coastal city in Nigeria, thereby creating serious problems in navigation, and irrigation. This can be
