Large marine animals key to assessing health of ocean ecosystems.
The article discusses how large marine animals like fish, turtles, birds, and whales can help us understand the health of the ocean. Scientists are using these animals to see if the ocean is in good shape or if there are problems like pollution or litter. They found that big fish can show us changes in the ocean in the short term, while whales give us a long-term view. They also discovered that biomarkers, which are like biological signs, can help us see if the ocean is healthy or not. This research can help us make sure the ocean stays in good condition for the future.
