Problem solving.
This is critical since in marine biology you need to study environments and how to help them or if they are good. but if you find the problem and have no ability to solve any problem your useless.
You need to be able to see how to fix the overpolulation of lion fish. and how to stop people from introducing areas to specific that font normally exist.
You also need to be able to solve overfishing without starving people since so many people use fish to live.
