CONTENT : CONTENT SL.NO INDEX 1. INTRODUCTION WATER POLLUTION 2. AIR POLLUTION 3. 4. INTRODUCTION ACKNOWLEDGMENT 5. BIBILIOGRAPHY 6. CONCLUTION 7. INTRODUCTION : INTRODUCTION Water pollution is a major problem in the global context. It has been suggested that it is the leading worldwide cause of deaths and diseases,[1][2] and that it accounts for the deaths of more than 14,000 people daily.[2] An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrheal sickness every day.[3] Some 90% of China's cities suffer from some degree of water pollution,[4] and nearly 500 million people lack access to safe drinking water.[5] In addition to the acute problems of water pollution in developing countries, industrialized countries continue to struggle with pollution problems as well. 2. WATER POLLUTION : WATER POLLUTION Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, groundwater). Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging either to individual species and populations, but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. 3. Slide 5: 4. Slide 6: 5. Slide 7: 6. INTRODUCTION : INTRODUCTION An air pollutant is known as a substance in the air that can cause harm to humans and the environment. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made.[1] Pollutants can be classified as either primary or secondary. Usually, primary pollutants are substances directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories. 7. AIR POLLUTION : AIR POLLUTION Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems. 8. Slide 10: 9. Slide 11: 10. Slide 12: 11 ACKNOWLEDGMENT : ACKNOWLEDGMENT I THANK THE PRINCIPAL, THE SUPERVISOR INCHARGES, AND THE TEACHERS FOR GIVING THIS OPPORTUNITY. 12. BIBILIOGRAPHY : BIBILIOGRAPHY I took from the internet www.Wikipedia.com www.Google.com www.Yahoo.com www.chrismadden.co.uk 13. CONCLUTION : CONCLUTION I conclude that we should not pollute the air and water because that is our natural environment. 14 You do not have the permission to view this presentation.
