cause acid rain to form.
release ozone into the stratosphere.
increase global warming.
Phosphorous and nitrogen from fertilizer wash into bodies of water and cause
ocean acidification.
ground level ozone pollution.
acid rain.
algae blooms.
This air pollutant is formed in the atmosphere when nitrogen oxides react with other compounds when they are activated by the sun's energy.
ozone
acid rain
carbon dioxide
VOC's
What negative effect do algae blooms have on industry?
It clogs the pumps on oil rigs.
Airlines have to fly different routs to avoid it.
Transport ships cannot move through the blooms so they must travel longer routes.

septic tank systems
stormwater runoff
both septic tank systems and stormwater runoff
water treatment plant discharge
What contributes the most to poor air quality?
Overfishing
Deforestation
Industrial factories
Industrial farms
What chemical or chemicals are harmful to the stratospheric ozone layer?
CO2
CFC's, Freon, aerosols
criteria air pollutants
nitrogen oxides
Ocean acidification poses a threat to
coral reefs - the acid eats away at the calcium carbonate that makes up the reef.
algae - the acid makes it harder for the algae to grow.
sea turtles - the acid weakens their shells.
kelp - the acid weakens their ability to keep their roots attached.
A human activity that increases erosion is
fertilizing yards.
commercial fishing.
crop rotation.
urbanization.
