Loss of biodiversity.
Air pollution.
Acoustic pollution.
Deforestation.
Water pollution.
Light pollution.
Solutions
• Creating protected areas where human activity is limited is
the best way to prevent deforestation and exploitation of
organisms and the resources they need to survive.
• Preventing species introduction
• Slowly climate change: Climate change is the documented
cause of several extinctions that we know about.
• Preventing consumism

over the past century, the Global Mean Sea
Level has risen by 4 to 8 inches (10 to 20
centimeters).
ACOUSTIC POLLUTION
Acoustic pollution is displeasing or
excessive noise that may disrupt the activity or
balance of human or animal life.
SOLUTIONS FOR ACOUSTIC
POLLUTION
• Controlling the industries and constructions, limiting the
use of their machinery or placing strategical acoustic
panels.
• Avoiding many peoples dialogues in which all people talk
at the same time.

SOLUTIONS FOR
DEFORESTATION
• Recycling, for avoid the necessity of raw materials.
• Reforestation.
• Agricultural policy: One of the biggest causes of forest loss
is, in the case of the third world, the extention of the
agricultural border by peasants seeking land to grow or
put to graze their cattle.
Water pollution
•
Water pollution accounts for the deaths of more than 14,000 people
daily.
• An estimated 700 million Indians have no access to a proper toilet, and
1,000 Indian children die of diarrheal sickness every day. Some 90%
of China's cities suffer from some degree of water pollution, and nearly
500 million people lack access to safe drinking water. In addition to the
acute problems of water pollution in developing countries, developed
countries continue to struggle with pollution problems as well.
• In the most recent national report on water quality in the United States,
45% of evaluated stream miles, 47% of evaluated lake acres, and 32% of
assessed bays and estuarine square miles were classified as polluted.
Solutions
-Never throw rubbish away anyhow. Always look for the correct waste bin. If there
is none around, please take it home and put it in your trash can. This
includes places like the
beach, riverside and water bodies.
- Use water wisely. Do not keep the tap running when not in use. Also, you can reduce the amount of
water you use in washing and bathing. If we all do this, we can significantly prevent water
shortages and reduces the amount of dirty water that needs treatment.
-Do not throw chemicals, oils, paints and medicines down the sink drain, or the toilet. In many cities,
your local environment office can help with the disposal of medicines and chemicals. Check with
your local authorities if there is a chemical disposal plan for local residents.
-Buy more environmentally safe cleaning liquids for the use at home and other public places. They are
less dangerous to the environment.
-If you use chemicals and pesticides for your gardens and farms, be mindful not to overuse pesticides
and fertilizers. This will reduce runoffs of the material into nearby water sources. Start looking at
options of composting and using organic manure instead.
Water pollution
• Industrial processes
• Oil spills
• Urban waste
• Modern agriculture
• Emission of pollutant gases
THE DESERTIFICATION
• Desertification is the development of desert-like conditions
in regions that have experienced human disturbance such as
deforestation, overgrazing, or poorly managed agriculture.
Effects of Desertification
• -Soil becomes less usable. The soil can be blown away by
wind or washed away rain.
• -Vegetation is Lacked or Damaged. Loosened soil may bury
plants or leave their roots exposed.
• -Causes Famine. Places that have war and poverty are most
likely to have famine occur.
• -Food Loss. The soil is not suited for growing food; therefore
the amount of food being made will decline.
• -People near Affected Areas. Desertification can cause
flooding, poor water quality, dust storms, and pollution.
Solutions for Desertification
• Construct windbreaks which minimize the erosive action of
the wind.
• Control grazing, as far back as possible to transhumance
livestock.
• Make special buildings such as terraces or diversions of river
courses.
What can WE do?
There are many thing we can do, for example:
• Change the lampposts
• Make laws for not enables buildings, for
example, banks, to have the lights on during the
night, when it isn’t necessary.
• Use light emitting diodes (LED) technology with
long wave length light in a red or yellow tint to
minimize impact and save energy.
• Shut off the lights when you can. Use timers,
dimmers, and sensors.
