How are we affecting the Environment?

1. Air pollution

a. Smoke, dust and exhaust fumes will pollute the air

b. Smog – a form of air pollution that is created when sunlight reacts with pollutant chemicals produced by burning fuels.

2. Acid Rain

a. Acid rain is rain or snow with a pH below 5.6 (it is acidic)

b. Kills plants and can change the pH of lakes and ponds (which can kill the animals)

c. Happens when carbon dioxide gas mixes with water molecules during the formation of rain drops.

d. Pollutants of sulfur and nitrogen oxides will form sulfuric acid and nitric acid

3. Ozone depletion

a. Upper ozone layer of atmosphere blocks out harmful radiation (UV radiation)

b. Ozone depletion – the thinning of the ozone layer due to air pollutants.

4. Greenhouse effect

a. Atmosphere is trapping heat , known as the green house effect

b. Greenhouse gases – carbon dioxide.

c. By-product of burning fossil fuels

Effects of Global Warming

1. Rainfall could decrease – affect food production and wildlife

2. Melt polar ice caps – flood coastal areas

3. Increase number and severity of storms

7. Groundwater pollution

a. Groundwater is water contained in the soil or trapped in underground pockets formed by nonporous rock.

b. Comes from rainfall and runoff that soak down through the soil

c. Can be polluted
