FACTORY Water pollution
Chemical Steam and smoke- Air pollution
QUANTITY OF co2 EMITTED IN ATMOSPHERE • 24 billionoftons a year
Effects of Air Pollution • Health problems • Damage to the environment • Thinning of the protective ozone layer of the atmosphere which is leading to climate changes
GreenhouseEffect Another serious danger that threatens the planet is the greenhouse effect, caused by the enormous amount of carbon dioxide and other greenhouse gases poured into the atmosphere. The increase of these gases due to the burning of fossil fuels and forest fires, is causing excessive heating of the planet. The consequences are devastating: the melting of ice at the poles, rising sea levels, an increase in desert areas and the drying up of farmlands.
Ozonehole The environment is subjected to severe hazards due to pollution. One of them is due to the placing of chlorofluorocarbons into the atmosphere, the gases contained in refrigerators and in aerosol spray cans. These gases had decreased the thickness of the ozone layer and, at the polar regions, caused even holes in it.
Ouch! What happened to my home?! Water Pollution
How Toxic substances dissolve or deposit in the water. Toxic substances enter lakes, rivers, streams, etc. Pollutants go down into the ground. Sources City sewage Industrial waste Agricultural run-off Water Pollution
Effects of Water Pollution • Devastating to people and animals, fish, and birds. • Unsuitable for drinking, recreation, agriculture, and industry. • Destroys water life.
OUCH!!! WHAT HAPPENED TO MY HOME?!
Types of waste Household waste Industrial waste Biomedical or hospital waste Why Population increases Increased plastics products Changes in lifestyle Landfills not well equipped to protect against contamination Solid Waste

Solutions to control noise pollution • Tree Plantation • Soundproof Homes • Loudspeaker Prohibition • Factory Location • Machine Quality AND…..
Reduce Reuse Recycle
Preserving what remains of the Earth and encouraging its renewal is our last hope of survival…….
