Should all fisherman from every country have to follow the same
rules?

Fresh WaterSurface Water- How does contamination occur?
Dumping of chemicals, sewage, and waste into rivers and lakes
Ground Water- How does contamination occur?
Seeping of chemicals through layers of ground above aquifer
Naturally occurring poisonous chemicals

Water TransferFresh water is unevenly distributed with
“have” and “have-not” areas
Diverting rivers into areas that are running lowsssss on water
Change the flow of the river
Increase salinity in oceans and impacts ecosystems around river
We are all CONNECTED- a small change can have a BIG impact

-Overfishing, oil spills and the garbage patch are major impacts of ocean pollution
-Biomagnificaiton
Fresh Water Pollution
