1. Exploration causes pollution.
Deepwater Horizon oil spill
Plastic pollution
2. Mining for resources is damaging.
It hurts the Arctic.
Burning fossil fuels adds to climate
change.
3. Overfishing is an issue.
Whales and dolphins are hunted.
Banned, but some countries still doing

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.
人们在谈论扩大海洋勘探的时候，通常指的是海洋开发。海洋勘探已经造成了许多问题，并将继续引发更多问题。
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.
扩大勘探意味着污染加刷。2010年“深水地平线”号钻井平台在海中溢出了两亿多加仑的石油。塑料污染也十分严重，导致许多鸟类和鱼类死亡甚至在我们的自来水中也发现了塑料污染。
谈论，讨论
mean doing v. 意味着
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.
资源开采极具破坏性，尤其是在北极地区。 由于气候变化，现在冰川减少了，这意味着我们可以在更北的地方寻找更多的化石燃料。但是，如果我们烧尽这些燃料，冰川将融化得更多，这一不良循环将持续下去。气候变化正警告我们情况不妙。
开采资源
恶性循环
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.
过度捕捞是另一个问题。鲸鱼和海豚也遭到捕杀，成为盘中美食或用于所谓的研究。尽管早在1982年就已禁止，但有的国家仍在无情地“谋杀”这些聪明的生物。
残忍地；毫无同情地
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.
..的家
海洋是生命的家园，而不是人类的私产。海洋广阔无垠，但比我们想象的更为敏感。 如果我们不保护它，子孙后代将不会原谅我们。

1. Sea exploration is important for our future.
Scientific research ships can help address
important issues like climate change.
2. Understanding more about the sea will also
us manage its resources better.
New medicines, food resources and energy.
Predict events such as earthquakes.

3. We need new resources for future
development.
Vast amounts of resources may be under
the sea and ice.

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.
v. 处理，设法解决
为了真正了解我们的星球，我们必须探索覆盖其表面大部分的海洋。 反对者也许会忧心忡忡，但是海洋探索对我们的未来十分重要。例如，科学考察船可以帮助应对像气候变化这种重要的问题。 我们需要了解我们的星球正在发生什么，这样我们オ能采取行动。因此，有必要开展更多的研究。
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.

深入了解海洋也有助于我们更好地管理其资源。记载新物种将提升我们对地球上生命的了解。这可能还会帮助我们发现新的药物，以及新的食物和能源来源。 深海探索还有可能会帮助我们预测地震等事件。

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.
世界人口正在不断增长，我们需要新的资源来维系未来的发展。 海洋和冰川之下可能蕴藏着大量的资源，不仅仅是石油和天然气，还有珍贵的矿物。

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.
当然，环境风险仍然存在。但是，这些风险应该与经济需求相平衡。随着技术的进步，我们有望会有更多的选择来驾驭这一平衡。

Dear Editor，
Recently our class has had a discussion about whether sea exploration should be carried out. But it is well known that the opinions concerning this hot topic vary from person to person.
As far as I am concerned, it's worthwhile to explore the sea for the benefit of future generations. Meanwhile, we should exploit the sea properly.
40% of the students are in favour of sea exploration. ...
Different people, however, have different opinions on this matter.
