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

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

Sustainability

What can you do to be more sustainable??
