Today we got to see conservation efforts in Hawaii and go on a hike. We saw a presentation on OTEC, saw a grape farm, learned about seals, and hiked down to a black sand beach. I learned about OTEC, which uses water temperature to generate electricity, how to teach a seal how to eat, and how to grow grapes quickly. My favorite part was the giant rope swing, which was super cool.
