POLLUTION

ACOUSTIC POLLUTION

• CAUSES

• Traffic noise is the main source of noise pollution caused in urban areas.

• Low flying military aircrafts landing over the national parks, and other vacant areas.

• Plumbing, boilers, generators, air conditioners and fans create a lot of noise in the buildings.

• Household equipments, such as vacuum cleaners, mixers and some kitchen appliances are noisemakers of the house.  

• EFFECTS• Deafness, temporary or permanent.

• Noise pollution acts as a stress invigorator.

• People can be victims of certain diseases like blood pressure, mental illness, etc.

• Most plants require cool & peaceful environment to grow. Noise pollution causes poor quality of crops.

• Animals are susceptible to noise pollution as well. It damages the nervous system of the animals.

• Noise indirectly weakens the buildings, bridges and monuments.

Acoustic pollution, also called noise pollution, is an excessive noise thatmay disrupt the activity or balance of human or animal life.

SOLUTIONS

• 1. To restrict vehicular horns up to a certain frequency

• 3. Educate students, employees, drivers of all vehicles about the noise pollution in masses.

• 4. Start off huge rallies against noise pollution

• 6. Punish those who violate this rule by imposing fine.

• 7. Keep factories far from cities areas.

Light pollution is caused byuncontrolled emissions andreflections.

Some causes of this pollution:

Light trespass  Over-illumination Glare Light clutter Skyglow

• Neurological disorders such as insomnia, migraine and depression.

• It interferes with the biological cycle of nocturnal animals, altering their feeding, migration and reproduction activities.

• Light pollution causes waste of energy and puts a strain on the already depleting resources on earth.

Light pollution, also known as luminous pollution is any illuminationof the night sky caused by obtrusive artificial light. The problem began with

the light bulb an invention developed out of necessity about 125 years ago.

LIGHT POLLUTION

CAUSES EFFECTS

ACOUSTIC AND LIGHT POLLUTION

•Some species like the belugas or the dolphins might be affected when migrating by acoustic pollution produced by all the vehicles from above

SOLUTIONS

• Use lower wattage light bulbs.

• Replace used lights. Don't use any lights when you don't specifically need them.

• Buy fixtures that fully encase bulbs so all the light is shining down where it's actually needed, not shooting off in every direction.

LOW VOLTAGE BULBS

WATER POLLUTION• It´s the contamination of water bodies.• It occurs when pollutants are discharged into water bodies without adequate treatment to remove harmful compounds .

• CAUSES• The industrial processes.• Urban waste.• Oil spills,• Modern agriculture • The emission of pollutant gases.

•EFFECTS•The death of aquatic animals

•Disruption of food chains,

•Deseases

•Destruction of ecosystems.

SOLUTIONS

Water Pollution Water Overexplotation

• The utilization of the wastewater, through debugging techniques such as ozonation or chlorination among others, for reuse in certain types of irrigation.

• Rationalize it’s use.

• Stop the waste.

• Take it to places where it is still lacking.

• Collect rainwater and make it drinkable.

Inside The Home:• Conserve water whenever possible.• Do not deposit any harmful chemicals or

medications down the drain.• Recycle and dispose household waste

properly.

Outside The Home:• Refrain from using fertilizers or pesticides

on lawns or gardens.• Preserve our forest, which are natural

water purifiers, by reducing paper use and by supporting reforestation.

• Don't deposit any waste or litter in any water system.

• Keep all boats and water crafts well maintained.

DEFORESTATIONIt´s the removal of forest, normally due to human activities.The main causes and effects are:

Causes Effects

Explotation of wood for furniture, paper, etc.

Loss of biodiversity

Explotation os minerals and resources under the forest

Erosion of soil

Expansion of urban areas and transport infrastructures

Less absorption of carbon dioxide and less production of oxygen

Clearing land for agricultural use Loss of the way of life of natives

SOLUTIONS

- Use different agricultural practices: Forest are not cut for free space for crops.

- Curb the felling of trees: By employing a series of rules and laws to govern it.

- Reforestation: Try to restocking of existing forests and woodlands that have been depleted through deforestation.

- Creation of wildlife santuaries or reserves: Where animals cannot be caught or hunted

- Reduce greenhouse effects: To prevent temperatures from rising

LOSS OF BIODIVERSITYBiodiversity refers to the number of different species of living

things that inhabitat a specific area.

-CAUSES

Global climate change

-The introduction ofgenetically modified especies.

-Pollution and contaminations

-Habitat loss and destruction

-Alteration in ecosystem compositio•The camalote and transgenic corn

SOLUTIONS

-Protecting Areas: Creating protected areas where human activity is limited or none.

-Preventing Species Introduction.

-Slowing or erradicate Climate Change.

-Promoting Sustainability: Sustainable agriculture is much better for the environment than grazing and cropping,

AIR POLLUTIONAir pollution is the contamination of air at its different levels. There are several problems:

-Smog

-Acid rain

-The hole in the ozone layer

We are going to focuse on acid rain

ACID RAINAcid rain is one of the consequences of air pollution. When any

type of fuel is burnt, various chemicals are released into the air. The factory´s smoke, also have a lot of invisible gases highly harmfull to our environment.

• CAUSES• It´s formed by sulfur oxide plus oxygen : S+O2 = SO2

• Much of SO2 (sulfur dioxide) emitted into the atmosphere comes from natural emission is produced by volcanic eruptions.

• However, a source of SO2 is mainly from general industries.

•EFFECTS

•The destruction of forests due to the effect acid rain causes in the leaves of the trees.

• The contamination of sensitive forest soils making them infertile.

•The contamination of lakes and rivers.

ACID RAIN

SOLUTIONS

• Reducing the maximum sulfur level in different fuels.

• Conversion to gas vehicles and government business enterprises.

• Do not add many chemicals on crops.

• Extension of electric transportation system.

• Follow kyoto protocol

DESSERTIFICATION

• Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife

CAUSES

•Droughts

•Climatic shifts

•Growing populations that increase pressure on fragile land resources

•Removal of vegetation

EFFECTS

• Soil becomes less usable

• Vegetation loss

• No crops can be grown

CONCLUSION

We are destroying a wonderful planet. And the choice to stop this madness is in our hands so little by little we have to start to create a better world for us and for the comming generations.
