As we continue our look at the Earth's oceans we now look at ocean resources. What resources that we use come from the ocean?
How are these resources acquired?
How are these resources used?
What are the effects of humans acquiring and using these resources?
Watch this Discovery Video and answer some of the questions it asks.

Why do plankton float to the top at night?

how does discharge of crude oil into the ocean by cargo ships is hurt the enviroment.
why are all the blue whales dieing if there are so many laws protecting them
if an mairena animal is effected by our effects on the ocen, can they show any symptons to sugest it?
We get fish and shrimp from hanging gigantic nets off the back of fishing boats that are as big as a football field! They also hang huge hooks off the back too.
Something very interesting is seaweed is used for shaving cream, ice cream, cheese, and curing cancer! In ice cream and cheese there is callageen and algin in shaving cream and ligin in some medicine used to help people cope with cancer.
How do animals that live in the bottom of the ocean with high pressure come up to the top of the ocean to breathe with the low presure???
They probably come up really slowly like when scuba divers take a small break every 10 feet while they come up.
How does a vampire octopus flip inside out to scare its attacker?
How do animals from the high pressure part of the ocean come up to breathe when their bodies are adapted to the high pressure on their bones
We know that life started under the ocean. Where did that occur and why?
why do sea turtles lay their eggs by the shore?
why cant they lay their eggs inside the sand in the water in the shore so its easier for the babie turtles? is it cus when the babies hatch they wont be able to breathe?
ok why do the sea turtals get a bunch of attention to stop hurting/catching them? what about indangoured sharks or killer whales? What about the animals that arent so cute and cudaly?
Steven,
the fish that live in high pressure areas do not come up to breathe. they filter the water for dissolved oxygen with their gills
Jake,
maybe they come up for more light. if a certain amount of light is admitted to their area during the day, maybe the area that admits that amount of light at night is closer to the surface. please tell me if that made no sense.
