environment encompasses all living and non-living things occurring naturally on Earth or some region thereof. It is an environment that encompasses the interaction of all living species.[1] The concept of the natural environment can be distinguished by components: * Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms, soil, rocks, atmosphere, and natural phenomena that occur within their boundaries * Universal

1. Discuss spread of communicable diseases and the environment’s mediating role. More people are at risk of communicable diseases than at any other time on history. Communicable diseases are worldwide problem requiring worldwide attention. Communicable diseases can weaken the strength of a nation's resources. In developing nations this poses an even greater threat. Diseases are threatening the economic stability of many developing nations. 50,000 people die everyday from infectious disease. Global

Paper II: Biological Study 1. Abstract 2. Introduction In recent years, stable isotope records in speleothems (i.e., calcium carbonate deposits found in caves) have become more and more important as proxies of past climate variability (e.g., Spotl and Mangini (2002), Fleitmann et al. (2004), Harmon et al. (2004)). Speleothems, whiczare found in most continental areas provide high resolution records and can be precisely dated by U-series (Scholz and Hoffmann (2008))

Forest ecosystem FOREST ECOSYSTEM A forest is more than just the trees. A single forest is a complete, functioning ecosystem that supports innumerable plant and animal species as well as earth, water, and air subsystems. The subsystems provide the essence of life of the forest and are in themselves a byproduct of forest systems, all of which are reciprocal and inter dependent. A forest ecosystem is a complex of living and non-living elements which interrelate. An ecosystem can be small

NEO-POSITIVISM STUART DODD (1900) Contributed the S theory as a qualitative systematic theory of society. The symbol S representing situation. Situations are of 4 components; time, space, population, and characteristics. GEORGE ZIPF (1902-1950) The guiding postulate of his theory is the “principle of least effort”- that is, in situations allowing alternatives, people choose those procedures that result in the "least average rate of probable work” WILLIAM OGBURN (1886-1959)

as polluted. Water is typically referred to as polluted when it is impaired by anthropogenic contaminants and either does not support a human use, such as drinking water, and/or undergoes a marked shift in its ability to support its constituent biotic communities, such as fish. Natural phenomena such as volcanoes, algae blooms, storms, and earthquakes also cause major changes in water quality and the
