Aquatic Ecosystems and Conservation

The video discusses the importance of conserving and protecting estuaries and intertidal zones, which are vital components of Earth's aquatic ecosystems. These ecosystems provide ecological balance, food, and raw materials like oil and natural gases. They include coral reefs, salt marshes, mud flats, and mangrove forests. However, industrialization poses a threat to these ecosystems, leading to their destruction and impacting communities that rely on them. The video emphasizes the need to understand the value of these ecosystems and outlines ways to conserve and protect them.
