Discussion
In groups, discuss the following questions and take notes.
1 What is your opinion about sea exploration Do you agree with one argument more than the other
From my perspective, sea exploration is a wonderful thing, which may well serve us human being in the future.
2 Are there any other aspects of sea exploration not mentioned that you think are important
Yes, there are. We need to explore the ocean so that we can better understand issues such as acidification which leads sea water to become more acidic, and how to deal with such problems.
Discussion
Write an argumentative essay on sea exploration
The following questions may help you.
What is the purpose of sea exploration
How does sea exploration help us to protect the sea
How does sea exploration cause damage to the sea
Is there a good balance between protection and exploitation
Writing
We should explore the ocean, first and foremost, because we do not know what we do not know. We thought we knew much about the ocean, but we were wrong. There could be life forms in the ocean, for example, that fit none of the categories we have for life. We already know many things about the ocean, but we need to learn more. A good example is ocean acidification, which is causing coral reefs to die. We know that using less fossil fuel would cause the process to slow down. We need more research to come up with plans and solutions.
To do the research, we have to enter an extreme environment not friendly to humans. This requires the development of new technologies that can also benefit us in other areas.
All in all, there are many good reasons to explore the ocean. If we care about science, about protecting our oceans, and about developing new technologies, we need to do all we can to support ocean exploration.
