What's the big secret of marine life? I love you, sea. What's the point?

The ocean accounts for 7 1% of the earth's surface area, and the whole ocean on the earth is a complete and huge ecosystem. Life in the sea is different from life on land, including tiny but abundant phytoplankton, unicellular protozoa and the largest blue whale among mammals. The ocean plays an important role in regulating the global climate and is rich in resources. The ocean will become an important source of energy, nutrition and raw materials for human beings in the future.

There are colorful corals, lovely fish, huge whales, colorful shells and grotesque starfish in the ocean. When human beings ask for rich resources from the ocean, they also bring a lot of damage, which in turn is retaliated by the ocean-typhoons, tsunamis, earthquakes, red tides and so on.

The oceans are mainly divided into four oceans: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean and the Arctic Ocean. The Pacific Ocean is the ocean with the largest area, the deepest depth and the most marginal islands. The Atlantic Ocean is the second largest ocean in the world, which is a bit like an S-shape. The Indian Ocean is the third ocean with a maximum depth of 7,450 meters, and is rich in natural assets. The Arctic Ocean lies in the northernmost part of the earth.

We must protect the marine ecological balance and collect marine resources reasonably.
