AGRICULTURE |
|
Agriculture (a term which encompasses farming) is the art, science or practice of producing food, feed, fiber and many other desired goods by the systematic raising of plants and animals. Agri is from Latin ager ("a field"), and culture is from Latin cultura, meaning "cultivation" in the strict sense of tillage of the soil. Thus a literal reading of the English word yields tillage of the soil of a field. In actual usage, Agriculture denotes a broad array of activities essential to food and material production, including all techniques for raising and processing livestock (see Animal husbandry) no less than those essential to crop planting and harvesting.

AUCTIONS AND E-COMMERCE |
|
An auction is the process of buying and selling things by offering them up for bid, taking bids, and then selling the item to the highest bidder. Auctioning can be traced as far back as 500 B.C.[1] In economic theory, an auction is a method for determining the value of a commodity that has an undetermined or variable price. Auctions can be with reserve or minimum, or without minimums, or absolute or no reserve. In reserve auctions, there is a minimum bid or reserve price; if the bidding does not reach the minimum, there is no sale (but the person who puts the item up for auction may still owe a fee to the auctioneer or auction company). In absolute or no reserve auctions, the sale is guaranteed, with only the price left to be determined. In the context of auctions, a bid is an offered price.

BUILDING SURVEYING |
|
Surveying is the technique and science of accurately determining the terrestrial or 3D space position of points and the distances and angles between them. These points are usually, but not exclusively, associated with positions on the surface of the Earth, and are often used to establish land maps and boundaries for ownership or governmental purposes. In order to accomplish their objective, surveyors use elements of geometry (latin: measuring the Earth), of engineering, mathematics, physics, and law.

FARM EQUIPMENT |

Farm equipment is any kind of machinery used on a farm to help with farming. The best-known example of this kind of equipment is the tractor.

HORSES |
|
The horse (Equus caballus or Equus ferus caballus) is a sizeable ungulate mammal, one of ten modern species of the genus Equus. Horses have long been one of the most economically important domesticated animals, and have played an important role in the transport of people and cargo for thousands of years. Most notably, horses can be ridden by a person perched on a saddle attached to the animal, and are also widely harnessed to pull objects like wheeled vehicles or plows. In some human cultures, horses are also widely used as a source of food. Though isolated domestication may have occurred as early as 4500 BC, clear evidence of widespread use by humans dates to no earlier than 2000 BC, as evidenced by the Sintashta chariot burials, thus firmly establishing the domestication of the horse.

POLLUTION |
|
Pollution is the release of environmental contaminants. Carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs), and nitrogen oxides produced by industry and motor vehicles are common air pollutants. Sunlight converts nitrogen oxides and hydrocarbons to ozone or smog. Water pollutants may consist of a wide range of organic and inorganic chemicals such as heavy metals, petrochemicals, chloroform, and bacteria. Water pollution may also occur in the form of thermal pollution and dissolved oxygen depletion. Soil contamination is an important aspect of environmental pollution; this phenomenon occurs when chemicals are released by spill or underground storage tank leakage. Among the most significant soil contaminants are hydrocarbons, heavy metals, MTBE, herbicides, pesticides and chlorinated hydrocarbons. The U.S., Russia, China and Japan are the world leaders in air pollution emissions; however, Canada is the number two country on a per capita basis.
