Water Ocean Water Why are oceans important? What resources do we get from the ocean? How have the oceans been polluted? What the the consequences of this pollution? Page Fresh Water Where does our fresh water come from? What are some of the advantages or disadvantages to surface water? Ground water? How do they become polluted? Which industry using the most fresh water? Why? What can we do to prevent pollution? Page

Human Impact

Garbage Patch

Ocean Pollution “The worlds dumping ground” Toxic chemicals Fertilizers Sewage Oil Thermal pollution Agricultural runoff

So what if the ocean is polluted??

Fish: A Case Study

Who owns the ocean? Who should be in charge of ocean resources?? Should all fisherman from every country have to follow the same rules?

Where are the fish going? Ocean pollution is increasing Overfishing is leading to declining fish stocks Estimated that 90% of all large ocean fish are now gone. New technology> fish Cod and Salmon in Canada

Not enough fish in the sea

What do you think can be done to protect ocean resources? Solutions: Stop eating seafood? Protecting breeding habitat Salmon hatcheries- problems? Aquaculture- problems?

Fresh Water Surface 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

Biomagnification Biomagnification or bioaccumulation Increase in the concentration of toxins as they move up the food chain

Water Transfer Fresh 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

Summary Ocean Pollution - excess chemicals, oil, agricultural runoff, plastics, and sewage are being dumped into our oceans -Overfishing, oil spills and the garbage patch are major impacts of ocean pollution -Biomagnificaiton Fresh Water Pollution Surface water and Ground Water Surface water is easily polluted Groundwater- can lead to naturally occurring chemical poisoning Water Transfer

Sustainability What can you do to be more sustainable??
