AIR POLLUTION It’s is the accumulation of hazardous substances into the atmosphere that danger human life and other living matter. Air pollution can be visible or invisible

WHAT CAUSES AIR POLLUTION? Natural disasters Transportation Industry Greenhouse gases

WHAT ARE THE RESULTS OF AIR POLLUTION? Global warming Acid rain

WATER POLLUTION It’s the introduction of chemical, biological and physical matter into large bodies of water that degrade the quality of life that lives in it and consumes it.

WHAT CAUSES WATER POLLUTION? Chemical pesticides Fertilizers Garbage

LAND POLLUTION It’s pollution of the Earth’s natural land surface by industrial, commercial, domestic and agricultural activities.

WHAT CAUSES LAND POLLUTION? Pesticides Fertilizers Trash

CONSEQUENCES OF AIR, WATER AND LAND POLLUTION ON HUMAN HEALTH Short-term effects Long-term effects

OTHER TYPES OF POLLUTION SOUND or NOISE POLLUTION - human, animal, or machine-created environmental noise that disrupts the activity or balance of human or animal life. LIGHT POLLUTION - is excessive and in most cases unnecessary direct or indirect artificial light that increases the level of brightness in the environment.

REDUCING POLLUTION Reducing pollution requires environmental, political, and economic leadership. Recycling Incineration Filtration of the air Purifying plants

WHAT CAN WE DO TO STOP POLLUTION?

INTERESTING FACTS ABOUT POLLUTION Approximately 1/3 of male fish in British rivers are in the process of changing sex due to pollution. Hormones in human sewage, including those produced by the female contraceptive pill, are thought to be the main cause. Fourteen billion pounds of garbage, mostly plastic, is dumped into the ocean every year. Over 1 million seabirds are killed by plastic waste per year. Over 100,000 sea mammals and countless fish are killed per year due to pollution. Each person in the U.S. produces about 4 pounds (2 kg) of garbage a day. Antarctica is the cleanest place on Earth and is protected by strong antipollution laws.
