From its perch on top of Mt. Carmel, the University of Haifa’s Department of Marine Biology has a clear view overlooking the Mediterranean. The oceans, which cover 70% of the Earth, are teeming with life, and represent a treasure trove, which can feed humanity and provide energy and medicines for future generations. But the oceans are also changing as a result of human activity. Marine biologists must fully assume their mandate as stewards of the sea--monitoring the oceans, understanding how they are changing, and guiding citizens and decision makers on how to preserve our natural marine heritage.
