Living with the blue ocean

Such an ocean, you know?

  The ocean provides food raw materials for the inhabitants of coastal areas. Ocean shipping connects the world, with approximately 90% of the world’s commodities being transported and traded by sea. Offshore wind can free us from our dependence on fossil fuels. The ocean absorbs 1/4 of anthropogenic carbon dioxide emissions every year, and produces 1/2 of the oxygen we breathe. It can also regulate regional and global climates through evaporation and ocean circulation. In addition to this, the ocean is also one of the world’s major repositories of biodiversity, with around 250,000 known species, with many more yet to be discovered.
  Three-quarters of the world’s large cities rely on the ocean for survival, and most of the human settlements are located near the coast. Hundreds of millions of people work in fishing and mariculture, shipping and ports, offshore energy and more, industries that depend on the products and services the ocean provides.

  As a result, the American military theorist Mahan proposed the concept of “sea power”. He believes that sea power determines national power, and whoever can effectively control the sea can become a world power. Throughout the history of the world, the rise of Spain, Portugal, the United States and other countries is inseparable from the control of important maritime hubs through powerful maritime forces, opening trade routes, and then controlling the global trade network.
When the ocean starts to “change”

  However, there are indications that marine ecosystems are deteriorating at an unprecedented rate and magnitude. This is due to both local pressures such as habitat destruction, overfishing and environmental pollution, as well as global phenomena such as climate change, unprecedented rapid changes in ocean temperature and acidity, which make the oceans more unpredictable, and impaired self-recovery ability.
  Ocean acidification will seriously affect the survival and reproduction of marine organisms, especially shellfish. After a series of biological functions are affected, it will also cause serious harm to individual behavior, population structure and marine ecosystems.
  Plastic pollution is also a big challenge to ocean health. Because some plastics degrade slowly, they accumulate in the ocean.

  It is estimated that there are approximately 5.25 trillion plastic particles floating in the world’s oceans, weighing a total of 250,000 tons, including microplastics (plastics less than 5 mm in diameter). Microplastics originate from the weathering and decomposition of larger plastic fragments, pellets used in plastic manufacturing, additives in cleaning and personal care products, and synthetic clothing.
  Due to their small size, microplastics can be mistaken for plankton by marine animals such as bivalves (mussels, clams) and fish and ingested. These marine animals, along with the pollutants they accumulate in their bodies, can be transferred through the food chain. As a result, all marine life faces problems such as poisoning, behavioural disturbances, starvation and suffocation caused by microplastic pollution. And corals, mangroves and seagrass beds are gradually being overwhelmed by plastic waste, depriving them of oxygen and sunlight.

  Climate change will cause ocean glaciers to melt, sea levels to rise, and coastal areas will face more frequent flooding. Studies have shown that if all the Antarctic glaciers melted, the sea level would rise by 66 meters, and the ocean would be like a giant beast, engulfing the human homeland.
Make the future ocean blueprint into reality

  The ocean is vital to humanity. For many years, it has been widely believed that the ocean is vast and that the products and services it offers are inexhaustible and inexhaustible. However, if humans want to take advantage of the direct and indirect products and services provided by the ocean, they must first have a healthy marine environment.
  China has been actively fulfilling its commitment to ocean protection, participating in international cooperation in ocean protection, and putting forward the concept of a community with a shared future for the ocean. Building a community with a shared future for the ocean and making the ocean a beautiful home that human beings can rely on, inhabit and cultivate forever has become a top priority.

  In order to promote international cooperation in the field of marine protection, the United Nations General Assembly has designated June 8 every year as World Oceans Day, and designated 2021-2030 as the “United Nations Decade of Ocean Science for Sustainable Development” to support relevant countries in the application of marine science. Carry out marine environmental protection and sustainable development.
  The world’s oceans are an interconnected whole. In order to achieve the goal of sustainable marine development, all human beings must actively cooperate to protect our oceans and our future!
