ENVIROMENTAL PROBLEMS
Slide 4
AIR POLLUTION: -Carbon dioxide, a greenhouse gas, is the main
pollutant that is warming Earth. Its associated with cars, planes,
power plants, and other human. One possible solution for this
problem can be to reduce pollution and carbon emissions. -Smog is a
photochemical that creates a dark, heavy mist and its formed due to
the reaction of some light with ozone and nitrogen oxides at ground
level. One of the possible solutions for smog, are to transfer
factories outside of the city to avoid the accumulation of smock in
the atmosphere of the city. -The ozone layer is essential to life
because it reduces the intensity of ultraviolet rays. Some holes
are appearing because of the chlorofluorocarbons. One solution is
to stop making CFCs and several other chemicals. -Acid rain is a
rain or any other form of precipitation that is unusually acidic.
One solution is to conserve energy or drive cars less.

WATER PROBLEMS -Water pollution occurs when pollutants are
discharged directly or indirectly into water bodies. Some solutions
for this problem are to buy more environmentally safe cleaning
liquids for the use at home and other public places or to Take
great care not to overuse pesticides and fertilizers. -Water
scarcity already affects every continent. Around 1.2 billion
people, or almost one-fifth of the world's population, live in
areas of physical scarcity. The only possible solution is to
consume less and save more water.

DEFORESTATION Deforestation refers to irresponsible cutting
down of trees in forested areas. Trees are vitally important to the
environment and the climate of the Earth. They are one of the
largest producers of oxygen and habitats and shelters to millions
of species. They act as filters of carbon dioxide. Some of the
reasons why forests are disappearing are overgrazing, forests
fires, mining, agricultural activities, urbanization and illegal
logging. The main consequences of deforestation are the soil
erosion, loss of biodiversity, disruption of the water cycle,
flooding and drought and the climate changes. One solution to
deforestation is to curb the felling of trees, by employing a
series of rules and laws to govern it.

DESERTIFICATION Desertification is a process of ecological
degradation that happen in the fertile and productive soil and lose
all or part of power production. Desertification occurs mainly in
semi-arid areas and bordering on deserts as a result of human
action. Causes: Overgrazing is the major cause of desertification
worldwide Cultivation of marginal land: lands on which there is a
high risk of crop failure and a very low economic return
Destruction of vegetation in arid regions.

Loss Of Biodiversity A major report, the Millenium Ecosystem
Assesment, released in March 2005 highlighted a substantial and
largely Irreversible loss in the biodiversity of the earth, with
some 10-30% of the mammal, bird and amphibian species threatened
with extinction, due to human actions

Important Data
Slide 14
What Can We Do? 1.Find Alternative Areas to plant our crops:
Instead of harvesting the rainforest, We should find any other area
with no Biodiversity Hotspot 2. Identificate the Biodiversity
Hotspots And Protect them. What can Governments do? 1. Collaborate
with Scientists to prevent Multinationals from abusing the Earths
resources 2. Use their founds to help prevent the loss of
biodiversity
Slide 15
Noise Pollution Noise pollution is displeasing or excessive
Noise that may disrupt the activity or balance of human or animal
life. The word noise is similar to the Latin word nauseas, which
means disgust or discomfort.
Slide 16
Important Data This Tunnel, in Melbourne, Australia, is
designed to Reduce Noise Pollution without harming Aesthetics.
Slide 17
What can We do to reduce Noise Pollution? 1. Do not use car
horns unnecessarily. 2. Motors, machines and vehicles also produce
loud noises when not maintained properly. Proper maintenance should
be carried out for better performance. 3. Avoid loud music, which
hurts your ears and others' ears. 4. Walk or cycle to school
Slide 18
LIGHT POLLUTION Light pollution, also known as photopollution
or luminous pollution, is the brightness or glow of light in the
night sky caused by the reflection and scattering of artificial
light in gases and particles from the air by the use of inadequate
lighting or excess lighting. Some solutions are: Lower the wattage
of all outdoor lighting. Use only the light you need to get the job
done. Use timers, dimmers, and sensors. Shut off the lights when
you can. Keep the light on the ground and the skies natural. Use
light emitting diodes (LED) technology.
