How have the oceans been polluted?
What the the consequences of this pollution?
Page 187-192
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?

What can we do to prevent pollution?
Page 201-210
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 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
Biomagnification Biomagnification or bioaccumulation
Increase in the concentration of toxins as they move up the food chain
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
SummaryOcean 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??
