6. Health Effects Frequent asthma attacks Breathing difficulties Premature death Birth defects Hard for body to receive oxygen Tired and dizziness Increase in heart attacks and stokes Lead can loser IQ Lead causes kidney failures Cancer Over exposure to UV rays Respiratory disease Frequent asthma attacks Breathing difficulties Premature death Birth defects Hard for body to receive oxygen Tired and dizziness Increase in heart attacks and stokes Lead can loser IQ Lead causes kidney failures Cancer Over exposure to UV rays Respiratory disease

7. How big of a threat is air pollution to us? Causes 1,600 deaths per yearCauses 1,600 deaths per year 45% of the year is highly polluted45% of the year is highly polluted When air is polluted, you can only see 8 kilometers in front of your faceWhen air is polluted, you can only see 8 kilometers in front of your face Industries are a big cause of pollution, not just cars.Industries are a big cause of pollution, not just cars. Pollution leads to many respiratory diseases and cancersPollution leads to many respiratory diseases and cancers The harmful toxic material in the air thins the ozone layerThe harmful toxic material in the air thins the ozone layer A thinner ozone layer means that more harmful sunlight reaches people and causes skin cancer, etcA thinner ozone layer means that more harmful sunlight reaches people and causes skin cancer, etc Causes 1,600 deaths per yearCauses 1,600 deaths per year 45% of the year is highly polluted45% of the year is highly polluted When air is polluted, you can only see 8 kilometers in front of your faceWhen air is polluted, you can only see 8 kilometers in front of your face Industries are a big cause of pollution, not just cars.Industries are a big cause of pollution, not just cars.
