The sea is a treasure house of resources, which provides human beings with food, energy, and raw materials for production. The development of marine resources is also inseparable from the concept of green development. China has a coastline of 18,000 kilometers, and many coastal cities are like a string of pearls on the west coast of the Pacific Ocean. The marine economy in the new era has brought well-being to the local people and continued the ecological wisdom of living in harmony with the sea.
