Answer:
Critical medical advances and sustainable forms of energy.
Step-by-step explanation:
- In the commentary "Why Exploring the Ocean Is Mankind’s Next Giant Leap", the narrator Philippe Cousteau says that since earth's oceans have been explored to only about 10 %, there is a great potential of finding new discoveries and resources there.
- He claims that we should explore the oceans to yield discoveries in critical medical advances and sustainable forms of energy. He put these claims based on the evidence of finding AZT, a treatment for HIV which is derived from a Caribbean reef sponge and the abundant availability of OTEC (ocean thermal energy conservation) and wave energy.
