Question 1 (The 2 main issue)
1)summer just a few years ago when oxygen-deprived waters killed 296,000 fish in Mattox Creek, Virginia.
2)When there are excessive loads of nitrogen and phosphorus in the water, algae can "bloom" to harmful levels, changing water color, and eventually stripping dissolved oxygen from the water when they die, fall to the bottom, and decay. This dissolved oxygen is critical to the health of Chesapeake critters and waters.
Question 2 (Discuss the negative)
Dead zones are low-oxygen, or hypoxic, areas in the world’s oceans and lakes, Because most organisms need oxygen to live, few organisms can survive in hypoxic conditions Dead zones occur because of a process called eutrophication, which happens when a body of water gets too many nutrients, such as phosphorus and nitrogen
3-The Floods' Lingering Effects: New Study Shows Gulf "Dead Zone" One of the Largest on Record
The Gulf "dead zone" threatens seafood production, recreation and marine life.
Extremely heavy rains and melting snows washed massive amounts of nutrients—particularly nitrogen and phosphorus—from lawns, sewage treatment plants, farm land and other sources along the Mississippi River into the Gulf of Mexico. Once in the Gulf, these nutrients, which are required for plant and crop growth, trigger algae blooms that choke off oxygen in water and make it difficult, if not impossible, for marine life to survive
4-Lake Erie, Chesapeake Bay, northern Gulf of Mexico, and the Baltic Sea.
5-Chesapeake Bay? Many coastal waters like Chesapeake Bay are susceptible to the formation of dead zones due to a combination of biological and physical factors
6- no it does affect us, but it has happened to us once
yes it cam reach our area
8-who/what-Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes, caused by "excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water.
9-What Can We Do to Remedy Dead Zones?, Using less fertilizer,Implement better practices of discharge of chemicals, Finding alternative methods for sewage systems
10- another solutions is that its kill humans because they are messing up our food and when we don't get no food at all than we all die; yes it will cause people are dying everyday because the don't have anything to eat or drink
