• One of the greatest problems that the world is facing today is that of environmental pollution
• Increasing with every passing year and causing grave and irreparable damage to the earth.
• Environmental pollution consists of five basic types of pollution, namely, air, water, soil, noise and light.

• Air pollution is by far the most harmful form of pollution in our environment.
• Air pollution is cause by the injurious smoke emitted by cars, buses, trucks, trains, and factories, namely sulphur dioxide, carbon monoxide and nitrogen oxides.

• Even smoke from burning leaves and cigarettes are harmful to the environment causing a lot of damage to man and the atmosphere.
• Evidence of increasing air pollution is seen in lung cancer, asthma, allergies, and various breathing problems along with severe and irreparable damage to flora and fauna.
• Even the most natural phenomenon of migratory birds has been hampered, with severe air pollution preventing them from reaching their seasonal metropolitan destinations of centuries.

• Of course water is very important for our society, and if we start saving it.
• We will pay less because we consume less and of course we will keep our environment clean.
• After we use water, it is not the same as it was before. It is polluted…

• Water pollution caused industrial waste products released into lakes, rivers, and other water bodies, has made marine life no longer hospitable.
• Humans pollute water with large scale disposal of garbage, flowers, ashes and other household waste.
• Acid rain further adds to water pollution in the water.

• In many rural areas one can still find people bathing and cooking in the same water, making it incredibly filthy.
• In addition to these, thermal pollution and the depletion of dissolved oxygen aggravate the already worsened condition of the water bodies.
• Water pollution can also indirectly occur as an offshoot of soil pollution – through surface runoff and leaching to groundwater.

• Noise pollution, soil pollution and light pollution too are the damaging the environment at an alarming rate.
• Noise pollution include aircraft noise, noise of cars, buses, and trucks, vehicle horns, loudspeakers.

• Industry noise, as well as high-intensity sonar effects which are extremely harmful for the environment.
• Maximum noise pollution occurs due to one of modern science’s best discoveries – the motor vehicle, which is responsible for about ninety percent of all unwanted noise worldwide.

• Library - 35 dB
• Office - 60- 65
• Normal traffic noise 70 - 80 dB
• Airport (plane take off) - 120 dB

• Soil pollution, which can also be called soil contamination, is a result of acid rain, polluted water, fertilizers etc., which leads to bad crops.
• Soil contamination occurs when chemicals are released by spill or underground storage tank leakage which releases heavy contaminants into the soil.
• These may include hydrocarbons, heavy metals,
MTBE, herbicides, pesticides and chlorinated hydrocarbons.

• Light Pollution includes light trespass, overillumination and astronomical interference.
• Effects on animals: Light pollution stops migrating birds of having any way of seeing the moon and stars.
• They use them to navigate the direction of their migration, therefore not being able to migrate to the correct place.

• Also, sea turtles do not come to shore and nest as often, because they are afraid of the lights.
• It also affects animals eyes as a flash of camera weakens the eyesight of animals.
• Effects on humans: Glare causes sleep problems in humans.
• Too much light in an apartment shining in from a nearby billboard will disturb their sleep.

• Also science is being affected by light pollution.
• Astronomers have no way of observing, or making discoveries with too much light to block the night sky.
• It also causes headache as when light directly falls into our eyes and affects the sensory nerves.

• Light pollution is the intrusion of unwanted or unneeded artificial light into a man-made or natural environment.
• A variety of somewhat separate phenomena comprise the overall issue of pollution due to excess artificial light:

• At a domestic level, exposure to smoke while cooking can be curtailed by the adoption of cleaner fuels, improved stoves, better ventilation and the use of biogas.
• The choice of the correct species of tree as fuel.

• For example, Acacia nilotica (babul) and
Casuarinas, produces less smoke as compared to species like mango and neem.
• Utilization of charcoal is relatively safer than burning firewood.
• Utilization of smokeless stoves will reduce exposure to smoke.

• Regular tests for automobile emissions should be made compulsory.
• Environmental groups should pressurize state governments to bring in this legislation.
• Non-leaded fuel alone should be sold.
Environmental groups must get together to pressurize the government.

• To make automobile manufacturers modify their designs to suit non-leaded fuel and stop the sale of leaded fuel.
• People should be encouraged to share their vehicles or use public transport.
• This would mean lesser traffic on the road, and thus, lesser pollution.

• Small pressure groups should be formed to influence industries to install filters, electrostatic precipitators, scrubbers, etc., to control atmospheric pollution.
• Education is the most important solution

• Plan campaigns in schools and colleges on simple issues such as the ill-effects of smoking.
• substitutes for domestic fuel consumption such as smokeless chulhas, etc.
• Mobilize your immediate locality to protest against local polluting industries.

• There are now several groups that are trying to prevent light pollution.
• Light pollution first made news in 1964, when an observatory was specially placed just to avoid light pollution.

• However, it wasn’t brought to the attention of most people until June 6, 2002.
• When the Czech Republic passed the world’s first light pollution law.
• Since then, light pollution is slowly being recognized by the general public as a major problem.

• You can lower the amount of light pollution by having lights off when they are not needed.
• You can also shield yourself from this pollution by putting curtains on a window facing the street or any other disturbing light source.

• It is now time to join hands across the globe to protect and preserve our environment.
• Thereby safeguard human health along with the natural environment: air, water, and land.
We need to preserve our wetlands, our rainforests, our farmlands and arctic zones.
• And we need to save the endangered species.

• The Greenhouse effect is the rise in the temperature of the Earth’s atmosphere.
• Due to certain gases like, methane, water vapour, nitrous oxide and carbon dioxide, which trap the energy and heat from the sun.

• Without these gasses, the heat would escape reducing the temperature of the atmosphere.
• These gases are commonly known as
Greenhouse gases, because they help to maintain the Earth’s average temperature.
• Simply put, it is a natural process which make the Earth’s atmosphere just right for life forms to flourish.

• Carbon dioxide () is one of the greenhouse gases. It consists of one carbon atom with an oxygen atom bonded to each side.
• When its atoms are bonded tightly together, the carbon dioxide molecule can absorb infrared radiation and the molecule starts to vibrate.

• Eventually, the vibrating molecule will emit the radiation again, and it will likely be absorbed by yet another greenhouse gas molecule.
• This absorption-emission-absorption cycle serves to keep the heat near the surface, effectively insulating the surface from the cold of space.

• Carpool.
• Walk or ride a bicycle.
• Shop by phone or mail.
• Ride public transit.
• Telecommute.

• Accelerate gradually.
• Use cruise control on the highway.
• Obey the speed limit.
• Combine your errands into one trip.
• Keep your car tuned and support the smog check program.
• Don't top off at the gas pumps.
• Replace your car's air filter.
• Keep your tires properly inflated.

• Saving the environment is not an issue anymore.
• It is a survival truth. Individuals, organizations and governments need to come together.
• And join hands to protect what is left of our planet so that the future is not wiped out before it’s time for curtain call.

• Global warming is rapid increase in the temperature of earth's atmosphere and oceans in the past few years.
• The negative effects of Global warming are heat waves, unusual warm weather, ocean warming, rise in sea level, and coastal flooding, warming of

• Arctic and Antarctic zones, changes in the pattern and amount of precipitation.
• Species extinction and melting of the glaciers which have proven to be extremely dangerous.
