  Video: Ingenious Video 8: Is the Answer to Overfishing… Algae? Mark as Favorite (3 Favorites)

  Omega-3s are an essential nutrient that humans have to get from fish. But many of the world’s wild fish species are in crisis because we’ve taken too many of them from the ocean. So the answer is to farm more of our fish, right? While fish-farming relieves some pressure on the ocean’s wild species, it also contributes to that pressure, since farmed fish are fed fishmeal made from wild-caught fish. That’s because fish don’t make their own Omega-3s either. Like us, they get them from their diet. Using technology that came out of the space program, scientists have developed a way to cut out the middle-fish from the food chain and harvest Omega-3s for fishmeal directly from the source: algae.

  Activity: Ingenious: Is the Answer to Overfishing… Algae? Video Questions Mark as Favorite (1 Favorite)

  In this activity, students will answer questions while watching the video, Is the Answer to Overfishing… Algae? from the Ingenious series produced by the American Chemical Society. Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates Omega-3’s, the essential nutrient that humans have to get from fish. However, fish don’t make their own Omega-3’s, and like humans, must get them from an important part of their diet, algae. But with over-fishing considerations and fish-farming limitations, scientists are working to develop a new way to harvest Omega-3’s to maintain stability.
