There are literally millions of products that could not have been made without sea life. Over 100 years ago, whale oil lit the dark nights of most of the world. Whale oil was made from the fat or blubber of whales. Even whale throw up is used. It is called "ambergris" and is a foul-smelling substance. When a whale throws up, particularly a big sperm whale, apparently the sound of it travels for miles through the water. The substance is worth millions of dollars and is still used today as an ingredient in perfume.
Another product that is widely used today is joint supplements made from shark cartilage. Sea kelp is also found in medicine and supplements for both humans and animals.
