Human Interaction
There is a lot of human interaction in the marine biome. There are both good and bad interactions. An example of a good interaction is fishing. (This is also mutualism!) We get the fish and it keeps from overcrowding populations in the ocean. A bad interaction is pollution. Although many people do not understand that they are polluting the ocean, they pollute by throwing their garbage on the beach, flushing it down the toilet, and putting it down the drain. Many people also dive in the ocean and coral reef areas. This really has no impact on the ocean.
