However, some human activities may harm ocean systems. For example, shrimp farming can destroy mangrove forests, disrupting marine food webs and releasing stored carbon. Plastic pollution and ocean warming create additional threats, while mangrove restoration, sustainable aquaculture, and responsible seafood choices can help protect ocean ecosystems.Sections:00:00 How can shrimp farming destroy mangrove forests?00:36 Mangrove forests and shrimp farms01:37 Why do mangrove forests matter?03:15 How do human activities affect ocean systems?04:53 How can we protect ocean ecosystems?05:38 Sustainable seafood choices06:05 SummaryTEKS Standards: SCIENCE.7.11, SCIENCE.7.11B------------------Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
