What is the main idea for Part Two? 4 As a scientist, I want to explore the great wonders our ocean has to offer. As a conservationist, I need to explore the vital human-ocean connection: how the ocean can provide for people and how our impacts affect the health of our oceans. This is critically important for us this century. Our population is rapidly growing toward 9 billion people and our demand for food, fresh water and energy is predicted to double. 5 Healthy oceans can help ease the increasing burden our population is placing on this planet, but we need to be able to explore, observe and learn about the oceans in their entirety in order to protect and conserve them effectively.
