Recently our class had a heated discussion on whether space is worth exploring. Students hold different ideas about it.
30% of us think space exploration is not worthwhile, holding the
belief that space exploration is too far away from us and our daily life and is a waste of money. However, 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.
As far as I am concerned, it is worthwhile to explore space. Not only can it promote the development of society but it can also enrich our life.
