6. Global warming
The major cause of global
warming:
The
burning of fossil fuels like
oil and coal cause greenhouse
gases to escape into the air
Deforestation (cutting down
trees).
7. The Greenhouse Effect is the
phenomena where gases in our
atmosphere trap heat from the
Sun and keep the Earth warm.
When operating naturally, the
Greenhouse Effect keeps
Earth's climate relatively
stable.
8. Acid rain
Acid
rain is made when sulfur
compounds react with water and the
oxygen in the atmosphere to create a
sulfuric acid solution.
There's
more acids that can be made
in the atmosphere and fall as acid rain
but they are much less common.
The
biggest component by far is the
sulfur compounds.
9. How Acid Rain Affects
People?
People can become seriously ill, and
can even die from the effects of acid
rain. Many can find it difficult to
breathe, especially asthma patients.
Asthma, along with dry coughs,
headaches, and throat irritations can
be caused by the sulfur dioxides and
nitrogen oxides from acid rain.
10. Acid rain can be absorbed by
both plants and animals (from things
they eat and/or direct contact). When
people eat these plants or
animals, the toxins inside of their
meals can affect them. Brain
damage, kidney problems, and
Alzheimer's disease has been linked
to people eating animals/plants.
12. Air pollution
The sources of air pollution:
Anthropogenic (caused by humans activity)
Mostly related to burning different kinds of fuel. They
include:
•
Dust bowl
•
Industrial activity in general.
•
Coal
•
Paint fumes, or other vapors.
•
Aerosol spray
13. Natural
• Volcanic
activity
•
Dust from natural sources, usually
large areas of land with little or no
vegetation
•
Gases, such as methane, emitted by
the digestion of animals, usually
cattle.
•
Smoke from wildfires.
14. Water pollution
A thing you don't see so easily which
comes out of factories, farms and cities is
the water pollution. This is the stuff that
get dumped into streams, into rivers, into
lakes and into seas.
