• 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
![Page 8: Environmental Problems and Solutions](https://reader038.fdocuments.net/reader038/viewer/2022102717/55a89f1f1a28abe7588b4569/html5/thumbnails/8.jpg)
Noise pollution
• 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.
![Page 9: Environmental Problems and Solutions](https://reader038.fdocuments.net/reader038/viewer/2022102717/55a89f1f1a28abe7588b4569/html5/thumbnails/9.jpg)
• 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.

Soil pollution
![Page 11: Environmental Problems and Solutions](https://reader038.fdocuments.net/reader038/viewer/2022102717/55a89f1f1a28abe7588b4569/html5/thumbnails/11.jpg)
Soil pollution
• 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.

Industrial Pollution
![Page 15: Environmental Problems and Solutions](https://reader038.fdocuments.net/reader038/viewer/2022102717/55a89f1f1a28abe7588b4569/html5/thumbnails/15.jpg)

Industrial 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.

Environmental Protection
![Page 22: Environmental Problems and Solutions](https://reader038.fdocuments.net/reader038/viewer/2022102717/55a89f1f1a28abe7588b4569/html5/thumbnails/22.jpg)
Environmental Protection
• 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.

Greenhouse Effect
![Page 24: Environmental Problems and Solutions](https://reader038.fdocuments.net/reader038/viewer/2022102717/55a89f1f1a28abe7588b4569/html5/thumbnails/24.jpg)
Greenhouse Effect
• 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.
![Page 25: Environmental Problems and Solutions](https://reader038.fdocuments.net/reader038/viewer/2022102717/55a89f1f1a28abe7588b4569/html5/thumbnails/25.jpg)
• 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.

Greenhouse Gases
![Page 27: Environmental Problems and Solutions](https://reader038.fdocuments.net/reader038/viewer/2022102717/55a89f1f1a28abe7588b4569/html5/thumbnails/27.jpg)
Greenhouse Gases
• 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.

Try combining driving with alternative modes of transportation
• Carpool.
• Walk or ride a bicycle.
• Shop by phone or mail.
• Ride public transit.
• Telecommute.

Driving smart keeps pollution at a minimum
• 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.

Global Warming On The Rise
• 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.

Saving the Environment
• 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.
