Human Impact and Dependence on the Ocean
4 different types of Human and ocean interactions
positive initially
positive initially
- Positive intentional
- negative intentional
- Positive unintentional
- Negative unintentional
We get minerals, food, and energy from the ocean
We pollute the ocean by runoffs, over fishing and, mining (chemical spills)

Fishing
There are many poeple who have been over fishing
They use nets to catch lots of fish.
There is usually a certain amount of fish that you are allowed to fish so that you don't make that species' population very low in a certain population
Over fishing can ruin the food web in the area that it happens

Run offs
Run off: water from rain or other sources of water that pick up pollution when they are running down a surface
it will pollute the environment (wildlife) where the water runs.
There are urban runoff from storm drains
over 80% of the pollution that enters the ocean is from land- based waster
Ways to help:
use chemicals for your yard carefully
Make sure your oil from your car doesn't leak because it can get into the run off water
it will pollute the environment (wildlife) where the water runs.

Dead Zone
it is a area in the ocean where there is very little oxygen in the water
they are growing around tropical islands
they are caused by runoffs and human population
the second biggest dead zone is the Gulf of Mexico

Artificial Reefs
It is a man-made reef in the ocean
Normally made out of steel or concrete because other materials can damage the reefs
Most of them are put in the ocean on purpose
Sometimes they are there by accident
Affects the population of fish by increasing the population
Overfishing in the artificial reefs will hurt the fish population
provide shelter and homes for fish and other marine animals

Oil Spills
It is a accidental release of oil into a body of water by humans
Affects everything in a ecosystem in a negative way such as fish, plants
Can be caused by oil drills or sunken ships with oil in it
humans are the main cause of oil spilled because we are the ones drilling or one the ships
Most oil spills are accidental but some are on purpose
Can hurt the fish and we might end up eating the fish and get hurt
humans help clean up oil spills, too

Climate Change
it is things such as global warming, pollution
Carbon dioxide is causing the climate change
Causing the oceans to get hotter because the climate is getting warmer
Affects the fish and other marine animals
Some species of organisms will die out because they can't survive in the warmer water
Humans are the main cause of it because we are the people burning the fossil fuels
