SEA EXPLORATION
REACHING OUT ACROSS THE SEA
REACHING OUTA CROSS THE SEA 跨海越洋
Trade and curiosity have often formed the foundation of mankind's greatest achievements. To complete the great map of the world was a strong passion for the people of early civilisations. Marco Polo’s tales inspired European explorers to search for sea routes from west to east.However, merchants and explorers from the East set sail from east to west many years before Columbus first did.

In ancient times,silk from China found its way overland to India,the Middle East,and Rome , along what became known as the Silk Road.A trading route across the sea was also extended along the coasts of the Indian Ocean, centred around Ceylon (now Sri Lanka).Here,merchants from China and many other places met to negotiate trade deals which also led to more awareness of each other’s cultures. Over the centuries, further trading allowed more exploration of the regions to the west of China,as recorded in Du Huan’s Record of My Travels in the eighth century.
Later, the Ming Dynasty further developed relations with these regions.Between 1405 and 1433, seven large fleets sailed west on voyages of trade and exploration.These fleets were a sight to behold and were in a league of their own at that time.Under the command of Zheng He ,they set sail from the South China Sea across the Indian Ocean to the mouth of the Red Sea,and then to the east coast of Africa.African royal families sent gifts such as giraffes as gestures of friendship in return for gold,silk,and spices.Although China withdrew from further expeditions after1433. these land and sea routes remained active channels between other cultures for centuries.

To reach out across the sea remains a strong desire today.The ancient sea routes travelled by Zheng He are being revisited with the 21st Century Maritime Silk Road,which is part of the Belt and Road Initiative.The aim of this initiative is to encourage cooperation and trade across the historic Silk Road areas and strengthen the bonds between China and the rest of the world.Trading has grown greatly in recent years,and will continue to do so in years to come.China has invested billions in systems and services along these routes,which will help to greatly develop the whole area for the benefit of future trade and cultural exchange.

China has also joined its friends across the sea on other important projects.Although the ancient sea routes of Zheng He have been travelled many times,there are still many other places left to explore. In recent years,China has joined other nations on several expeditions to explore the Arctic.From a scientific point of view,there is an urgent need to study the Arctic in order to understand climate change and its effects.
Hundreds of years on. and with the latest technology in hand.the need to trade and the desire to enhance relationships will drive China to reach out across the sea far into the future.

When people talk of exploring the sea more, they usually mean exploiting it.Sea exploration has caused many problems and will continue to cause more.
More exploration means more pollution. The Deepwater Horizon spilled over 200 million gallons of oil into the sea in 2010. Plastic pollution is also bad, killing many birds and fish, and has even been found in our tap water.
Mining for resources is very damaging, especially in the Arctic. Because of climate change, there is less ice now, which means we can look for more fossil fuels further north. But if we burn these, the ice will melt more and this negative cycle will continue. Climate change is warning us that something is very wrong.
Overfishing is another problem. Whales and dolphins are also hunted for their meat or for so-called research. Although this was banned in 1982, some countries are still"murdering "these intelligent creatures without mercy.
The sea is home to life, not human beings'possessions. It is huge, but it is more sensitive than we think. If we do not protect it, future generations will not forgive us.

To truly understand our planet, we must explore the oceans which cover most of it. Opponents may be concerned, but sea exploration is important for our future. For example, scientific research ships can help address important issues such as climate change. We need to understand what is happening to our planet so that we can take action. Therefore, more research is necessary.
Understanding more about the sea will also help us manage its resources better.Logging new species will improve our understanding of life on the earth. It may help us discover new medicines, as well as new sources of food and energy. Accessing the deep ocean may also help us to predict events such as earthquakes.
The population of the world is growing and we need new resources for future development. There are probably vast amounts of resources under the sea and ice, not just oil and gas but also valuable minerals.
Of course, there are still environmental risks. However these should be balanced with economic needs.
Hopefully, as technology improves, we may have more options for managing this balance.
