(06.03 MC) What benefits do wind turbines provide in the marine environment that oil rigs do not? (3 points)

(06.04 HC) You farm kelp and sell the kelp for food and as fertilizer. The wastes from the kelp can be used in an integrated aquaculture system in which kelp farming can be coupled with farming of fish or abalone.
