Atmospheric Heating‚ Weather Fluxes‚ and Their Effects on Our Health The article “Is Global Warming Harmful to Health?” states that not many scientists believe in the idea that the atmosphere is heating up. They do‚ however‚ believe that the rate of heating is hastening and that the impacts of the temperature change could begin to be a problem. Problems such as: glacier melts‚ flooding‚ oceans warming up‚ a shift in arable lands‚ and sporadic‚ unpredictable weather patterns and storms. And these

pollutants enter waterways‚ the environment is encouraging for algae and algal blooms which have an invasive property and have the ability to quickly take over the waterway. Should the above scenario occur‚ there would be a very evident decrease of fish life in the water as the algae’s consume large amounts of oxygen therefore deoxygenizing the water making it near impossible for fish to survive. Some forms of algal blooms can fatal‚ and can affect livestock‚ wildlife‚ marine animals and humans.

caused by run-off from agricultural land. Eutrophication is caused by an excess amount of nitrate and phosphate in water bodies. It is usually caused by fertiliser run off and dumping of sewage going into waterways (basically human activity). Algal bloom is the direct result of eutrophication where suffocation of aquatic life and nutrient depletion may occur. Professionals may use a colorimetric analysis to measure the absorption of light from coloured water sample using a colorimeter to determine

The computer was born not for entertainment or email but out of a need to solve a serious number-crunching crisis. By 1880 the U.S. population had grown so large that it took more than seven years to tabulate the U.S. Census results. The government sought a faster way to get the job done‚ giving rise to punch-card based computers that took up entire rooms. Today‚ we carry more computing power on our smartphones than was available in these early models. The following brief history of computing is

With reference to examples you have studied‚ assess the effectiveness of attempts to control water pollution. Water pollution is the contamination of areas of water‚ such as rivers‚ lakes and groundwater. It affects plants and organisms that live in these areas and can be damaging to the health‚ and survival of them. Water pollution occurs when pollutants are directly or indirectly discharged into the water without being treated. The area of Rotorua – New Zealand contains 17 lakes‚ some of which

nutrient supply. The main nutrients that are present in cultural eutrophication are P and N containing compounds coming from sewage. Some algae and blue-green bacteria can live off of these compounds and rapidly grow in number. This phenomenon is called algal blooming. Eventually‚ the rate in growth is so great that it becomes unsustainable in natural systems. Since eutrophication is a worldwide phenomenon and is of great importance economically‚ much effort and money has been put into creating models

24 October 2011 Dam the Politics... Save the Salmon There are some things in this world that mean more to us than we can explain. We as human beings have an existential connection to all of mother earth’s creatures. We are approaching a dark time in the Klamath River‚ soon there will be no natural born salmon spawning up what was once one of the rivers that spawned the most salmon in the Pacific Northwest. The salmon that at one time flourished in the Klamath‚ are not able to reach their natural

Literature Review From the the Encarta encyclopaedia 2010 Water pollution is any chemical‚ physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives in it. Dr. Shachin Cartlon (2009) states Water pollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water. The sources of water pollution are categorized as being a point source or a non-source point of pollution
