WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1.7% in glaciers and the ice caps of Antarctica

Acid Rain Definition: The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852‚ when the English chemist Robert Agnus invented the term. From then until now‚ acid rain has been an issue of intense debate among scientists and policy makers. Acid rain‚ one of the most important environmental problems of all‚ cannot be seen. The invisible gases that cause acid

Philosophers of soft determinism state

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

What is acid rain? Rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm‚ typically to forests and lakes. What chemicals make rain acidic‚ and how does it happen? Besides water‚ and carbonic acid (from carbon dioxide dissolved in the rain droplets)‚ the primary components of acid rain are sulfuric acid‚ which comes from sulfur dioxide derived from the burning of coal‚ and nitric acid‚ which from nitrogen emissions. Where do these chemical come from? These

"In every sense‚ a standing rain forest supplies more economic wealth than if it were cleared yet deforestation continues at an alarming rate." (Tropical Rain Forest Coalition‚ 1996). Rain Forests have played a significant role in shaping modern biology. The destruction of the rain forests will determine the fate of all species humans plants and animals. Many people do not understand the long- term consequences of losing the earth’s rain forests. They have provided all living beings with many

This essay is to examine both the pros and cons of legalizing “soft drugs”. Hard and Soft drugs are terms to distinguish between psychoactive drugs that are addictive and perceived as especially damaging and drugs that are believed to be non-addictive (or minimally addictive) and with less dangers associated with its use. The term "soft drug" implies that the drug causes no or insignificant harm one such drug is cannabis (marijuana).Cannabis is a psychotic drug. The main psychoactive ingredient

The soft drink industry is highly competitive. Characteristics of the industry include slow growth and maturity‚ a phase during which weak companies are weeded out of the market by the strongest corporations. In order to stay competitive‚ soft drink companies must be able to offer their product at a low price. A price that can at least match (or preferably‚ beat) a competitor’s price will allow that product to enter into a consumer’s mental set of possible brands to purchase. Because the pop industry

Oganda‚ who asks for news about when it will rain. Labong’o is cryptically speechless. Notably‚ with Ogot’s immediate presentation of this critical concern about whether or not rain will come‚ the reader may at once expect that this concern will be resolved favorably; the title--and there is no evidence that it is meant ironically--assures that "the rain came." Thus‚ the tension raised by this concern shifts to a different question: the rain will presumably come‚ but at what cost? Labong’o’s attitude signals
