In groups, discuss the following questions and take notes.

I think sea exploration is a wonderful idea, because even if there are no immediate rewards for it, to explore and find out more about our world is always a good thing.
Discussion
2. Has your opinion changed after reading the two texts
Why or why not
Yes, my opinion has changed. Before reading Text 1, I did not know that sea exploration could add to sea pollution, via deep sea drilling for example.
3. Are there any other aspects of sea exploration not mentioned that you think are important
We do not know what we don’t know; We need to explore the ocean so that we can better understand issues such as acidification which leads to seawater to become more acidic, and how to fight these problems; Studying the ocean causes the creation of new technologies that can help us in other areas.

The Importance of Protecting Our Oceans
As we all know, there are varieties of resources under the sea. However, the past ten years has witnessed that some creatures have died out due to the marine pollution, which has been greatly concerned by the whole world.
On the one hand, we must make people realize the importance of protecting the ocean. As a matter of fact, to protect the ocean is to protect human beings. On the other hand, the government should take immediate measures to keep the balance of nature. Only by raising people’s awareness of protecting the environment and making joint efforts to prevent pollution can the problem be solved.
