Yolonda Agnew While there are many things we do daily to keep ourselves healthy, many environmental factors can adversely affect our health: the air we breathe, the land we live on, and the water we drink. Bad air quality can irritate our eyes, throat, and nose, cause breathing problems, aggravating asthma and other respiratory problems. In addition, breathing bad air for extended periods can cause more severe health problems, such as heart

Many interesting biological facts but usually, when modifications or experiments are tried, the investigator has some reason for doing so. A substance in the gaseous or liquid state consists of molecules or atoms that are independent, rapid, and random in motion. These molecules frequently collide with each other and with the sides of the container. In a period of time, this movement results in a uniform distribution of the molecules throughout the system. This process is called diffusion (Everett

(IRC) raised concerns of an issue Coke experienced which is the claim of overconsumption and pollution of scarce water resources due to plant operations and production. This affected many cities and regions of the country, especially in the communities of Kerala and Mehdiganj (Carroll & Buchholtz, 2012, p. 649). In addition to the scarcity of water, there were also complaints of the water around the soft drink giant’s plants tasting and smelling bad. Donated waste to farmers for fertilizer tested

sustainable use of soils and in the process minimise soil erosion and other forms of land degradation. 3.2.10 Causes of soil degradation in South Africa. Erosion. Erosion is the detachment and transportation of soil materials by wind or water. Soil erosion is a major problem of agriculture in South Africa. Soil erosion is a natural process but it becomes a serious problem when the activities of humans accelerate the process of its occurence. Land degradation caused by soil erosion causes

where the process of mixing sand, water, and chemicals (many which are known to be harmful) are forced under very high pressure down into the shale rock through the horizontal part of the drill. The extreme pressure causes the shale rock to fracture releasing the natural gas within. The added chemicals help reduce problems such as a buildup of bacteria and mineral deposits. Fracking is a very water intensive process and uses up to four million gallons of fresh water for each well, and with about

are, mostly, confined to the parts of biosphere that receive solar radiation during the day. As stated above this includes atmosphere, the surface of land, the few meters of soil and the upper layers of water of oceans, lakes and rivers. The illuminated zone may be a few centimeters in turbid water of a river, and up to about 100 meters in clearest part of an ocean. In the ocean, the biosphere does not end where light ceases as gravity enables the energy flow to continue downward, since fecal pellets

for a location where the earth’s interior heat is brought within our reach. This is most common at plate boundaries. Direct heating systems are designed to supply hot water only with no electricity generation. Borehole drilled to depth of 1800 meters beneath the city of Southampton, UK. Near the bottom of the hole is water at 70˚C. The fluid contains dissolved salts. The fluid is more accurately described as Brine. The Brine is pressurized and so rises unaided to within 100 m of the surface

the top, like a tombstone, definitely dedicated to someone whose name she couldn’t quite read. It didn’t matter anyway. It was raining hard enough to see the rain come straight down like elongated bullets. The bus arrived in the rain, spewing water on both sides. The girl in the black rain coat sauntered up the stairs of the Tri City Transit Bus, paid her fare, and found an empty seat on the crowded bus. Despite the rain coat’s unflattering bagginess, it wasn’t hard to tell she was a beautiful
