Effects of air pollution. (In detail)

Places where there are more pollution (which countries, in What type of area). (In detail)

What can we do to reduce air pollution? (In detail)

Percentage of polluted air in the atmosphere. (In detail)

Answer 1

causes - mostly anthropogenic meaning humans emit the pollution. CO2 (cutting down trees...think about where this happens), carbon monoxide (emmitted from vehicles...not just cars), ozone (O3 gets trapped in the troposphere), you also have to think about other types of greenhouse gases...not many people realize that water vapor is also a greenhouse gas. It's not pollution though.

effects - pollution causes smog which can cause lung cancer if exposed over time if smog is bad enough. also think about the Black Lung disease that plagued many in England over a century ago. (pollution can be indoors too)

places - the most common would be in any urban city (Mexico City, LA, Atlanta, NYC, London, Beijing, Lagos etc)

reduce - CONSERVE ENERGY! that's the simplest answer but it's not that easy especially since alot of the world is so dependent on oil. stop cutting down trees, use less oil, use renewable energy (wind, solar, hydro)

%age - I don't know about the percentage of polluted air but I do know that in the IPCC report it says that CO2 is currently at about 370ppb; in the natural cycles throughout Earth's lifespan it has never gone over 270ppb and that was during interglacial periods. In 100 years it is projected to increase to over 500 ppb. If CO2 keeps increasing, the atmosphere will probably become poisonous. You might want to look up the most recent IPCC report for this one (and possibly impress your teacher)
