CHESAPEAKE BAY

THERE ARE MANY PROBLEMS THAT POLLUTES

• The four I picked are:
• Air Pollution
• Blue Crabs
• Oysters
• Stormwater Runoff

AIR POLLUTION

• Air pollution comes from several sources.
• Pollution is released in the air we breathe.
• Nitrogen and chemical contaminants are two pollutants that harm both air and water.
• The process through which air pollution settles onto land or water is called atmospheric deposition.

AIR POLLUTION

• Atmospheric deposition occurs in several stages.
• First, pollution is emitted into the air, where wind and weather can carry it over long distances.
• Airborne pollution particles fall onto the land or into the water, sometimes in the form of dry particles
• and sometimes attached to rain, snow or other precipitation.
• Even pollution that falls onto the land—rather than straight onto the water’s surface and goes into rivers and streams.

BLUE CRABS

• They are aggressive bottom dwelling predators.
• The blue crab population is vulnerable to increased harvest pressure, as well as the effects of habitat loss due to poor water quality
• The main affect of the blue crabs we harvest to many so not all thing are taken care of that they normally do.

OYSTERS

• The interaction of over-harvesting, disease, sedimentation and poor water quality has since caused a
• severe decline in their numbers throughout the Chesapeake.
• Oysters are important to the bay because the filter water, and provide habitats and food.
• We are also harvesting to many oysters too.
• Without them the water may not be filter properly and other animals may die.

STORMWATER RUNOFF

• Any precipitation in an urban or suburban area that does not evaporate or soak into the ground,
• but instead pools and travels downhill, is considered stormwater.
• Stormwater from urban and suburban areas contributes a significant amount of pollutants to the Bay.
• 17 percent of phosphorus, 11 percent of nitrogen and 9 percent of sediment loads to the Bay come from stormwater.

CONCLUSION

• I think all of the things on the website should be taken care of.
• The four I listed were air pollution, blue crabs, oysters, and stormwater runoff.
