Global Warming| By: Alma Toric “…We are what is wrong, and we must make it right. ” -Al Gore, Nobel Peace Prize Acceptance Speech, Oslo, Norway, 10 Dec 2007 (http: //www. stthomas. edu/recycle/warm. htm)
Global warming is a significant increase in the Earth's climatic temperature over a relatively short period of time as a result of the activities of humans. Factors of contribution are: CO 2; burning fossil fuels, cars, power stations Methane; agriculture, coal-mining, oil exploration Nitrous Oxide; burning rain forests & human/animal wastes, fossil fuel combustion CFCs; found in fridges, air conditioners, aerosols http: //www. geoenergy-solutions. com/images/cars. jpg

How Global Warming is Affecting the 21 st Century…
Malaria| • endemic in 107 countries today; numbers will rise due to warmer temperatures that will attract mosquitoes north • 350 -500 million people get malaria every year and 1 million of these result in death • primary victims are young children, pregnant women and non immune adults http: //graphics 8. nytimes. com/images/2006/06/27/world/malaria. 600. jpg • symptoms: fever, sweats, chills, headache & nausea • transmission of Plasmodium parasite into blood stream causes infection and destruction of red blood cells and clogging of capillaries to vital organs and the brain http: //blog. bioethics. net/images/malaria_mosquito. jpg
Current places affected by malaria http: //www. fda. gov/Cb. ER/blood/malaria 071206 sk. htm By 2020 based on a global temperature increase of 1ºC & no human efforts to contain the spread of malaria
Cholera & Dengue Fever| • diarrheal illness due to the bacteria Vibrio Cholera • infectious disease carried by Aedes aegypti mosquitoes carrying dengue virus • waterborne disease • vector borne disease • from contaminated water or food http: //letsgoeverywhere. files. wordpress. com/2007/ 11/cholera. jpg • symptoms: sever headache, muscle, joint pain, and “dengue rash” • bacteria grows in small intestine • cholera outbreaks typically follow zooplankton blooms • no vaccine/often deadly http: //i 271. photobucket. com/albums/jj 158/derixc/denguefever. jpg • blooms are the result of an excess of nutrients such as phosphorus, excess carbon and nitrogen • warmer conditions allow mosquitoes to survive over a wider area and at higher altitudes • travels in the blood stream and then starts multiplying itself in the whole body http: //www. newsday. com/media/photo/200407/13580641. jpg
Flooding| • ability for warmer air to hold more moisture can lead to increase in floods • disruption of precipitation patterns • heavy rain cause disturbance to land destroy freshwater and marine environments • 80% of flooding increase will affect South and Southeast Asia • water related diseases are causing 80% of all illnesses and deaths; cholera, malaria and water contamination http: //www. swamppolitics. com/news/politics/blog/katrina-new-orleans-flooding 3 -2005. jpg • health conditions depend on the success of the harvest for some countries; flooding will wash away crops and encourage growth of fungi http: //www. medway. gov. uk/print/flooding. jpg
Droughts| • drought temporarily disturbs the ecological regime, creating conditions favorable to the spread of certain insect pests and plant and animal diseases http: //socialistresistance. org/wp-content/uploads/2008/05/kenya-drought 1. jpg • more water could be removed from agriculture and put into urban use • decreased plant growth; no vegetation leading to malnutrition impacts the young and child growth • food supply in 2050 will greatly impact the world population of 9 billion; water shortage for crops http: //www. climatelawupdate. com/Drought, %20 Sono ran%20 Desert, %20 Mexico; %20 Wikipedia. jpeg • high temperatures that cause droughts can also cause heat waves
Air Pollution| http: //www. geography. hunter. cuny. edu/~tbw/wc. notes/13. air. pollution/smoke. stack. pollution. jpg • air pollution kills about 5 900 Canadians each year • main factor is the burning of fossil fuels • others pollutants such as carbon monoxide, nitrogen oxide etc. and increased low level ozone cause problems such as chest infections, asthma, emphysema low level ozone is what creates smog • burning forests increases the number of cases of eye irritation, respiratory illness and cardiovascular disease http: //upload. wikimedia. org/wikipedia/commons/d/d 1/Shanghaiairpollutionsunset. jpg
How Can You Help? | • Recycle • Take the bus/walk/bike • Don’t leave the lights on • Less heat and air conditioning • Buy energy efficient products • Plant a tree
