We All Cause air pollution
• We cause air pollution when we use
electricity, other home fuels and
transportation .
• We also cause air pollution indirectly,
when we buy goods and services that use
energy in their air production and delivery.
Carbon dioxide (co2) is a good indicator of how
much fossil fuel is burned and how much of other
pollutants we cause to be emitted .
Using co2 as an example ,the united states is one
of the most countries that cause pollution , the
average family in the United states causes air
pollution in the following ways :
• Cars, buses and other modes of transport
• Fossil fuels burning
• Sulphuric acid
• The main effect of air pollution is acid rain
which causes severe damage to fish and
other water animals.
• The acid and causes damage to rocks,
animal and plants
Causes :
The main contributors to pollution are :
Agriculture: which causes pollution by
fertilizer , herbicides and pesticide,
• Industry: industry has potential to cause
serious pollution by dumping material ,
including poisons , into water
• People activities: Sewage plants treat
waste water before it re-enters rivers or
the sea , and they remove some harmful
products
Health effects of
the pollution we
cause :
Like ozone and particular matter,
cause respiratory and other health
problems , particularly in children
and elderly
Environmental effects
Indirect effects include increases in
infection disease ,
Weather-related deaths . And food and
water shortages . All these effects put a
stress on ecosystem and agriculture, and
threaten our planet as a whole
Causes:
Recycle your rubbish , it all ends in a
large hole in the ground certain materials
(e.g plastics ) are non-biodegradable and
do not decay into the soil
Glass , cans , certain plastic and paper
are all materials that are easy to recycle .
Most supermarkets have recycling bins
on their property
Effects
The effects on the human
health , animals , agriculture
and the environment and so
on its effects on the economy
Pollution made a lot of changes on
our environment one of them was
the climate changes which caused
the global warming
What Is global warming
The progressive gradual rise of the earth's
surface temperature thought to be caused by
the greenhouse effect and responsible for
changes in global climate patterns. An increase
in the near surface temperature of the Earth.
Global warming has occurred in the distant past
as the result of natural influences, but the term
is most often used to refer to the warming
predicted to occur as a result of increased
emissions of greenhouse gases
• The main causes are man-made causes
probably do the most damage . There are
many man made causes pollution as one
of the biggest man-made problems
pollution comes in many shapes and sizes
Percent of General information The cause
producing
carbons
40% Carbon dioxide emissions stem Power plants
from the burning of the fuels for
purpose of electricity generation
33% Carbon comes of burning of Cars and trucks
gasoline
12% Building structure account for Buildings
about 12% of carbon dioxide
emissions
15% While carbon dioxide is the Green houses
principal greenhouses gas,
methane, is second most
important according to the IPCC
methane is more than 20 times
as effective as CO2 at trapping
heat in the atmosphear
Sequences of global warming
• 1- natural accidents like twisters , forest ,
fires , heat waves , dryness , flowage and
draughts
Drought in Ethiopia Hurricane
• 2- changes in the food cycle which causes
hunger in many countries
• 3-negative effects on the economic
• 4- health effects
*Global warming made a huge changes in the
climate . Our whether is getting more heat and ice
is melting which made the sea level rise and all of
that was a reason for many natural accident 2
happen
*changes on whether also effected on the
agriculture which normally effected at food cycle
and was a cause a hunger and death at the end .
Climate related catastrophes in poor countries
are likely to spiral out of control unless action is
taken to tackle global warming …
*changes at the food cycle effected and human
health have economic impacts
The impact of global warming in Asia
Heat waves and periods of unusually warm weather
Ocean warming, sea-level rise and coastal flooding
Glaciers melting
Arctic and Antarctic warming
Malcolm Rodgers said “ country is being
devastated by these so-called natural disasters ,
and we and others are simply picking up the
pieces . The terrible irony is that the poorest
countries are suffering and we believe this is
because of pollution by the wealthiest “
he also said “we talk about natural accidents or
disasters , or acts of god , but they are actually the
acts of human beings we have changed nature “
The ozone hole
What is Ozone?
Ozone is a molecule
of three oxygen
atoms bound together
(O3). It is unstable
and highly reactive.
Ozone is used as a
bleach, a deodorizing
agent, and a
sterilization agent for
air and drinking water.
At low concentrations,
it is toxic.
Ozone is found naturally
in small concentrations in
the stratosphere, a layer
of Earth's upper
atmosphere. In this upper
atmosphere, ozone is
made when ultraviolet light
from the sun splits an
oxygen molecule (O2),
forming two single oxygen
atoms Each single oxygen
atom then binds to an
oxygen molecule to form
ozone. Stratospheric
ozone has been called
"good" ozone because it
protects the Earth's
surface from dangerous
ultraviolet light
Although ozone pollution is
formed mainly in urban and
suburban areas, it ends up
in rural areas as well,
carried by prevailing winds
or resulting from cars and
trucks that travel into rural
areas. Significant levels of
ozone pollution can be
detected in rural areas as
far as 250 miles (150 km)
downwind from urban
industrial zones.
Effects of Ozone
When you inhale ozone, it
travels throughout your
respiratory tract.
Because ozone is very
corrosive, it damages the
bronchioles and alveoli
in your lungs, air sacs
that are important for
gas exchange (see How
Your Lungs Work for
details). Repeated
exposure to ozone can
inflame lung tissues and
cause respiratory
infections.
Ozone exposure can
aggravate existing respiratory
conditions such as asthma,
reduce your lung function and
capacity for exercise and
cause chest pains and
coughing. Young children and
the elderly are most
susceptible to the high levels
of ozone encountered during
the summer.
In addition to effects on
humans, the corrosive nature
of ozone can damage plants
and trees. High levels of ozone
can destroy agricultural crops
and forest vegetation.
Protecting the ozone layer a checklist for citizen action :
What you can do to protect the ozone layer.
•Car Air Conditioners
•Old Appliances
•Home Air Conditioners and Other Appliances
•Other Actions
Ozone Depletion is a Fact!
