Global Warming|

“…We are what is wrong, and we must make it right.”
-Al Gore, Nobel Peace Prize Acceptance Speech,
Oslo, Norway, 10 Dec 2007

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:
CO2; 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

How Global
Warming is Affecting
st
the 21 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

• 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

Current places
affected by
malaria

By 2020 based on a
global temperature
increase of 1ºC & no
human efforts to
contain the spread of
malaria
Cholera & Dengue Fever|
• infectious disease carried by
Aedes aegypti mosquitoes
carrying dengue virus
• diarrheal illness due to the
bacteria Vibrio Cholera
• vector borne disease
• waterborne disease
• from contaminated water
or food

• 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://i271.photobucket.com/albums/jj158/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

Flooding|
• ability for warmer air to hold more moisture
can lead to increase in floods
• disruption of precipitation patterns
• heavy rain can cause disturbance to land and
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-flooding3-2005.jpg
• health conditions depend on the success of
the harvest for some countries; flooding will
wash away crops and encourage growth of
fungi

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-drought1.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

ran%20Desert,%20Mexico;%20Wikipedia.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

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
