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.

ECONOMIC ANALYSIS |
|
Economic base analysis was developed by Robert Murray Haig in his work on the Regional Plan of New York in 1928. Briefly, activities in an area divide into two categories basic and non-basic. Basic industries are those exporting from the region; non-basic (or service) industries support basic industries. Because of data problems, it is not practical to study industry output and trade flows to and from a region. As an alternative, basic and non-basic concepts are operationalized using employment data.

ELEVATOR |
|
An elevator is a transport device used to move goods or people vertically. Outside North America, elevators are known more commonly as lifts, although the word elevator is familiar from American movies and television shows, just as some Americans are aware of lift from imported entertainment. Other languages may have loanwords based on either elevator (e.g. Japanese) or lift (e.g. Cantonese). Because of wheelchair access laws, elevators are often a requirement in new buildings with multiple floors.

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.

REAL ESTATE |
|
Real estate or immovable property is a legal term (in some jurisdictions) that encompasses land along with anything permanently affixed to the land, such as buildings. Real estate (immovable property) is often considered synonymous with real property (also sometimes called realty), in contrast with personal property (also sometimes called chattel or personalty).
