Half a million more people died in floods in 1939 and another 2 million died in floods in 1959 (Cooley 2006). And periodic droughts are worsening China’s water-supply challenges, as described. The distribution of water in China, as in other countries, is highly variable in both space and time. While parts of China have abundant natural water resources, other regions are naturally arid and water scarce. For example, in Northern China, the water crisis is apparent.
The effects of pollution on the Great Lakes Region: The Great Lakes are located on the north-eastern border between the United States and Canada. They include lakes Huron, Ontario, Michigan, Erie, and Superior. Together they form the largest fresh water collection on Earth (Wikipedia, 2010). The surrounding American and Canadian population of the Great Lakes basin is 36 million people and covers an area of 75,000 square kilometres (Tremblay & Gilman, 1995). As a result of the large number of inhabitants surrounding the lakes and the many industries that depend on the area, the environment is subject to several ecological hardships such as sewage disposal, agricultural/urban runoff, and industrial effluent (Beeton, 1965).
Assignment #3.1 “Determining Causes and Effects-Draft Version” “Determining the Causes and Effects of Water Pollution in Lake Huron” By: Maricel N. Johnson November 28, 2012 Eng 115 (Tuesday Class) Professor: Michael Hunter Lake Huron is the third largest of the lakes with 3,540 feet of water, with it’s average depth is 195 feet and with maximum depth of 750 feet. The Great Lakes, Lake Michigan, Erie, Ontario, Superior and Huron are our largest freshwater system. Lake Huron contains many wildlife and is in danger of being polluted. This pollution is harmful to fish, wildlife animals, and to humans of the region. Determining the cause and effects of water pollution in Lake Huron contributes to finding solutions for cleaning up our waterways and improving public health.
MPs, bereaved parents, health professionals and junkies themselves say radical measure are needed to stamp out the city’s problem – the worst in Europe. Drugs deaths have risen sharply in recent years. In 1992, 43 young Glaswegians died; last year, the figure was 97 out of total of around 140 north of the border. In a city of 650,000 people the rate is worryingly high. Compared to the rest of Britain, it is shocking.
Two thirds of the fresh water is locked up in glaciers, leaving only 1% of the earth's water for human consumption (The World Water Organization). Global warming, urbanization and increasing demand have posed challenges for the quality and availability of drinking water globally and in the U.S. as well. The U.S. has one of the safest public drinking water system. There are around 60,000 Community Water Systems (CWS) serving 300.2 million people. In addition, there are over 100,000 Transient and Non-transient Non CWS serving 20 million people (EPA).
Over the years the marshlands that served New Orleans against storm surge have been destroyed by off shore drilling. An average of 34 square miles have dissapeared each year for the past 5 decades. New Orleans was made up of low income touristism imployment August 23, 2005 The National Hurricane Center in Miami,issues it first advisory.Hurricane Katrina is avout 350 miles east of Miami (NG) August 24th, The 11th storm of 2005 has been named “ Katrina” Its closing in on Miami, the winds are blowing at about 40 miles an hour. August 25th, Katrina is becoming stronger with winds at about 75 miles a hour and are exceding.Strom Katrine is now a hurricane. Falling trees kill two people.
This meant that any fish that would try to swim down to the bottom of the lake would die due to lack of oxygen. This then cut down a high level of cichild which ate at the bottom of the lake. Some other factors that affected Lake Victoria are the pollutants that are caused by humans such as sewage that were untreated, waste than ran into the lake, and the effects of agriculture. The total of all these activities by humans combined have crushed Lake Victoria’s sensitive ecosystem. Another major provider to the ecological balance of Lake Victoria’s was the initiation of the Nile perch.
This affects the central nervous system of fish so that they are paralyzed and can't breathe. As a result, red tide blooms often result in dead fish washing up on beaches. Red tides often occur when fresh water runoff creates a stratified surface layer above colder nutrient rich waters. Fast growing algae quickly strip away nutrients in the upper layer, leaving nitrogen
So far, this year remains among the top five more active seasons when compared to others this time of year (Holthaus, 2012). Bad weather affects the tourism industry, which is the number one source of income for some countries. Even in the United States, hurricanes will destroy so much of the coastal region that businesses and residents suffer for years. The stock market can be sensitive to hurricane predictions. For example, this past May, futures for orange juice climbed 7% in anticipation of storms Alberto and Beryl, even though Alberto eventually missed land and Beryl caused no damage to citrus groves at all.
For thousands of years, it has been a major _trade_______ route, and central to Chinese life. But for much of China's history, this river has also been responsible for ____destruction__________ on a massive scale. In 1994, the Chinese government began construction on the _____Three Gorges Dam_____________________. At 1.4 miles long and 630 feet high (roughly the height of a 50-story building), it is the world's largest dam.
