...MINING AND WATER POLLUTION Water is essential to life on our planet. A prerequisite of sustainable development must be to ensure uncontaminated streams, rivers, lakes and oceans. There is growing public concern about the condition of fresh water in Canada. Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend. Water has been called “mining’s most common casualty” (James Lyon, interview, Mineral Policy Center, Washington DC). There is growing awareness of the environmental legacy of mining activities that have been undertaken with little concern for the environment. The price we have paid for our everyday use of minerals has sometimes been very high. Mining by its nature consumes, diverts and can seriously pollute water resources. Negative Impacts While there have been improvements to mining practices in recent years, significant environmental risks remain. Negative impacts can vary from the sedimentation caused by poorly built roads during exploration through to the sediment, and disturbance of water during mine construction. Water pollution from mine waste rock and tailings may need to be managed for decades, if not centuries, after closure. These impacts depend on a variety of factors, such as the sensitivity of local terrain, the composition of...

...Fish farming Fish farming or pisciculture is the principal form of aquaculture, while other methods may fall under mariculture. Fish farming involves raising fish commercially in tanks or enclosures, usually for food. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species used in fish farming are carp, salmon, tilapia and catfish.[1][2] There is an increasing demand for fish and fish protein, which has resulted in widespread overfishing in wild fisheries, China holding 62 percent of the world's fish farming practice.[3] Fish farming offers fish marketers another source. However, farming carnivorous fish, such as salmon, does not always reduce pressure on wild fisheries, since carnivorous farmed fish are usually fed fishmeal and fish oil extracted from wild forage fish. The global returns for fish farming recorded by the FAO in 2008 totalled 33.8 million tonnes worth about $US 60 billion.[4] In 2005, aquaculture represented 40% of the 157.5 million tons of seafood that was produced, meaning that it has become a critical part of our world's food source even though the industry is still technically in its 'infancy' and didn't really become well known until the 1970s. Because of this rise in aquaculture, there has been a rise in the per capita availability of seafood globally within the last few decades.[5] Major categories of...

...In 1989, Exxon Corporation caused one of the worst environmental disasters. The oil tanker Exxon Valdez spilled 250,000 barrels, an amount equal to more than 10 million, into the waters of Alaska’s Prince William Sound after striking Bligh Reef at approximately 12:04 a.m. on March 24. The spill eventually covered 11,000 square miles of ocean and coated 1,300 miles of coastline. Shortly after the incident, different media piled in to begin extensive coverage often pointing out Exxon’s corporate irresponsibility. Company’s efforts to contain the spill were not good enough and slow but Exxon’s response was even slower. In addressing the problem, it tool company officials 10 hours after the accident to deploy booms that will contain the spill. Company executives refused to comment on the accident for almost a week and refusing to acknowledge the extent of the problem. In addition, statements made to the press by high-ranking executives were often inconsistent and contained contradictory information making the press question the credibility and truthfulness of Exxon. After the Exxon Valdez ran aground, the company conducted all its communication from the small town of Valdez, Alaska. This area proved inadequate, having only limited communication capabilities. Exxon seemed unwilling to disseminate its information using any other method or location. But the biggest criticism the company received was the fact that CEO Lawrence Rawl waited nearly six days to make a public statement...

...Introduction to Air Pollution: Air pollution is the presence of foreign substances (pollutants) in the atmosphere, emitted by industries and motor vehicles that cause damage to living organisms. Air pollution is the leading cause of several diseases. During the past few years, air pollution has emerged as one of the leading causes of death worldwide. Air Pollutants: Air Pollutants refer to the liquids, solids and gases that are not normal constituents of air. Presence of such substances beyond tolerable limits may be hazardous to plant, animal and human life. Air pollutants include oxides of carbon, nitrogen and sulphur, halogenated and non-halogenated hydrocarbons, suspended inorganic particulate matters, inorganic and organic acids, insecticides, bacteria, viruses, etc. Also read: Essay on Environmental Pollution: Causes, Effects and Solution Characteristics: Air pollution characteristics in a particular region are influenced by: * The type and amount of pollutant and their source of emission. * The topographical and meteorological conditions affecting dispersion, concentration and trans-boundary transport of pollutants. * The type of technology and various raw materials used in the manufacturing process and the type and quantum of emissions. * The extent of industrialization and population density.

...DEFINITION FROM WIKI (understand and write it yourself) In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbanceby resisting damage and recovering quickly. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation and the introduction of exotic plant or animal species. Disturbances of sufficient magnitudeor duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which a different regime of processes and structures predominates.Human activities that adversely affect ecosystem resilience such as reduction of biodiversity, exploitation of natural resources,pollution, land-use, and anthropogenic climate change are increasingly causing regime shifts in ecosystems, often to less desirable and degraded conditions. Interdisciplinary discourse on resilience now includes consideration of the interactions of humans and ecosystems via socio-ecological systems, and the need for shift from the maximum sustainable yield paradigm to environmental management which aims to build ecological resilience through "resilience analysis, adaptive resource management, and adaptive governance". The concept of resilience in ecological systems was first introduced by the Canadian ecologist C.S. Holling in order to describe the persistence of natural systems in the face of changes in ecosystem variables...

...Chapter 8: Renewable Energy Sources The Sustainability Revolution John C. Ayers "In a sense, the fossil fuels are a one-time gift that lifted us up from subsistence agriculture and should eventually lead us to a future based on renewable resources." Kenneth Deffeyes (2001) "I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that." — Thomas Edison, 1931 We cannot create or destroy energy. We can only capture it. The sun provides either directly or indirectly nearly all of the energy available to us. Plants capture solar energy directly through photosynthesis. Fossil fuels contain the energy of sunlight captured hundreds of millions of years ago. Photovoltaic (PV) cells also capture sunlight energy directly. Other energy sources capture the energy of sunlight indirectly. Heat from the sun powers the flowing air and water. We usually capture the kinetic energy of wind and water by using turbines that transfer the energy to an alternator, an electrical generator that produces alternating current. Geothermal energy is different in that it captures flowing heat energy produced by radioactive decay in the earth’s interior. In this chapter we will see that Wind, Water, and Sun (WWS) energy sources are sustainable because they are renewable, clean, safe, and nearly carbon-free. Although they have low energy densities, meaning that they require large areas of land or water to produce energy...

Irregular Plural Nouns………………………………………………..19 2 The usage of derived abstract nouns in “Oliver Twist” by Charles Dickens…….22 Conclusion………………………………………………………………………....29 Bibliography………………………………………………………………………30 INTRODUCTION The word "noun" comes from the latin nomen meaning "name." Word classes like nouns were first described by Sanskrit grammarian Pāṇini and ancient Greeks like Dionysios Thrax, and defined in terms of their morphological properties. For example, in Ancient Greek, nouns can be inflected for grammatical case, such as dative or accusative. Verbs, on the other hand, can be inflected for tenses, such as past, present or future, while nouns cannot. Aristotle also had a notion of onomata (nouns) and rhemata (verbs) which, however, does not exactly correspond our notions of verbs and nouns. Expressions of natural language will have properties at different levels. They have formal properties, like what kinds of morphological prefixes or suffixes they can take, and what kinds of other expressions they can combine with. but they also have semantic properties, i.e. properties pertaining to their meaning. The definition of nouns on the top of this page is thus a formal definition. That definition is uncontroversial, and has the advantage...

...The Origins of the Chinese Empire, to 220 C.E. these cities, built by rulers to move troops and supplies, were traveled by traders transporting such items as metal tools and utensils, lacquered wood plates and boxes, silk, pottery, gems, salt, and lumber. A money economy emerged, using copper coins called cash, with center holes for stringing them together for counting and carrying. China's towns and cities were likewise linked into a large economic system . Trade between China and distant lands A metal bell from the Zhou era. was difficult and dangerous, but by the era's end commerce was conducted by sea with Southeast Asia and by land routes crossing Central Asia. The Central Asian Connection Central Asia, a vast expanse to China's north and west where the climate was too dry for farming (Map 2), was home mainly to pastoral nomads who grazed herds on its plateaus and plains. Skilled on horseback, the nomads occasionally attacked Chinese settlements to carry off goods and supplies, but they also spread commerce and useful knowledge. Some nomads, for example, exchanged their Central Asian nomads connect China with other cultures Nomads and Chinese adopt horse riding and crossbows from each other Iron tools and weapons spread to China, enhancing farming and warfare hides, wool, and horses for Chinese silk, pottery, metalware, and wood products and then traded these items with other societies across Central Asia.

Banana Musa x paridasiaca Description Origin and Distribution Varieties Climate Soil Propagation Culture Harvesting Yield Handling and Packing Controlled Ripening and Storage Pests Diseases Food Uses Animal Feed Other Uses Folklore The word "banana" is a general term embracing a number of species or hybrids in the genus Musa of the family Musaceae. Some species such as M. Basjoo Sieb. & Zucc. of Japan and M. ornata Roxb., native from Pakistan to Burma, are grown only as ornamental plants or for fiber. M. textilis Nee of the Philippines is grown only for its fiber, prized for strong ropes and also for tissue-thin tea bags. The so-called Abyssinian banana, Ensete ventricosum Cheesman, formerly E. edule Horan, Musa ensete Gmel., is cultivated in Ethiopia for fiber and for the staple foods derived from the young shoot, the base of the stem, and the corm. Most edible-fruited bananas, usually seedless, belong to the species M. acuminata Colla (M. cavendishii Lamb. ex Paxt., M. chinensis Sweet, M. nana Auth. NOT Lour., M. zebrina Van Houtee ex Planch.), or to the hybrid M. X paradisiaca L. (M. X sapientum L.; M. acumianta X M. balbisiana Colla). M. balbisiana Colla of southern Asia and the East Indies, bears a seedy fruit but the plant is valued for its disease-resistance and therefore plays an important role as a ";parent"; in the breeding of edible bananas. ...

...Earthquake From Wikipedia, the free encyclopedia This article is about the natural seismic phenomenon. For other uses, see Earthquake (disambiguation). [pic] An earthquake (also known as a quake, tremor, temblor or seismic activity) is the result of a sudden release of energy in theEarth's crust that creates seismic waves. Earthquakes are measured with a seismometer; a device which also records is known as aseismograph. The moment magnitude (or the related and mostly obsolete Richter magnitude) of an earthquake is conventionally reported, with magnitude 3 or lower earthquakes being mostly imperceptible and magnitude 7 causing serious damage over large areas. Intensity of shaking is measured on the modified Mercalli scale. At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacing the ground. When a large earthquakeepicenter is located offshore, the seabed sometimes suffers sufficient displacement to cause a tsunami. The shaking in earthquakes can also trigger landslides and occasionally volcanic activity. In its most generic sense, the word earthquake is used to describe any seismic event — whether a natural phenomenon or an event caused by humans — that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults, but also by volcanic activity, landslides, mine blasts, and nuclear experiments. An earthquake's point of initial rupture is called its focus orhypocenter. The term epicenter refers to the point at...
