[升格作文]

Is it necessary for humans to explore oceans?

Recently our class has had a discussion about whether sea exploration should be carried out.

Some of the students are in favour of sea exploration.They say sea exploration has made it possible for people to discover new medicines as well as new sources of food and energy.

Others are against it.Although sea exploration might help improve our understanding of the life on the earth，it might bring about marine pollution，which finally leads the ocean creatures to death.It also might cause ecosystem destruction.

Personally，sea exploration should be balanced with economic needs.Hopefully，as technology improves，we may have more options for managing this balance.

A discussion about the relationship between economic development and environment protection was held in our class.

【参考范文】

A discussion about the relationship between economic development and environment protection was held in our class.

Some students believe we should never sacrifice environment for economy.They think the present environmental problems are largely caused by rapid economic development.

However，other students think it unnecessary to consider environmental problems now because economic development comes first.They believe that environmental problems can be dealt with later when we have the time and money.

I think the second view is completely wrong.The purpose of economic development is to provide a comfortable and happy life for our people.We should aim at sustainable development and find a balance between the two.
