From the perspective of national conditions of resources or regional economic development, it is urgent for junior high school clubs to develop marine economy!

In recent years, marine science and technology have advanced by leaps and bounds, and new exploitable marine resources have been continuously discovered. The ocean has become a huge source of wealth, which shows a new dawn for solving the two major problems of resources and environment that plague human survival and sustainable development. First, the marine new energy resources represented by submarine natural gas hydrate resources and submarine polymetallic nodule resources are huge. Second, the family of marine new drug resources is huge. Third, the extraction, development and utilization of deep-sea gene resources have broad prospects. It is estimated that the market potential of deep-sea genetic resources can reach $3 billion/year. Fourth, the prospect of comprehensive utilization of seawater resources is optimistic. With the sharp drop in the cost of seawater desalination, the world seawater desalination market has been expanding at an annual rate of 10%. In a word, in the last 10 year of the 20th century, the development of marine science with multi-disciplinary linkage made new marine resources continuously discovered, which triggered the arrival of a worldwide "marine century" characterized by comprehensive development and protection of the ocean.

The ocean is the treasure house and the last space for human survival and development. The eyes of developed countries will turn from outer space to the ocean, and human society is marching into the ocean with a brand-new attitude. Ocean will become the main field of international competition, including economic competition led by high technology. It has formed four major marine pillar industries in the world-offshore oil industry, coastal tourism, modern marine fishery and marine transportation. The development of marine industry in the world has experienced the upgrading of industrial structure from resource consumption to technology and capital intensive, and marine economy is and will continue to become a new growth point of global economy.
