Under the Sea Information

Life is teeming under the sea. On one hand, you have microscopic unicellular diatoms, on the other, enormous whales. Plants of unimaginable beauty grace the mangroves and seagrass habitats, while coral reefs provide home to countless organisms and creatures, with a beauty and serenity rivaling anything in the ocean. Fish and other marine life live close to the ocean’s surface. They live deep in the abyss of the ocean floor depths. All marine life plays an important role in keeping our climate balanced. This is why it is crucial to educate people on the importance of keeping our marine environment safe and clean. Because if one system is damaged, it affects us all.
