One possible version:

Recently, students in our class have had a discussion on whether space is worth exploring.

30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.

On the other hand, 70% think space is worth exploring because we have benefited a lot from it, such as using satellites for communication and weather forecast. What’s more, with further space research, we may solve the population problem by moving to other planets one day. Also, space research will enable us to find new sources to solve the problem of energy shortages on the earth.
