Outer Space Explorations ,YES or NO?
We had an argument over whether it was necessary to carry out outer space explorations at a class meeting the other day.Some students were agree to the outer space explorations.Thay believed that through the outer space explorations,people could not only acknowledge new knowledge,but also get new resources from outer space.On the other hand,outer space explorations could enlarge our living space.
However,some students hold the opposite ideas,thay think that it takes a great sum of money to carry out such a grand project.What's more,the safeties of the astronauts could not been guaranteed.
As far as I'm concerned,the advantages of the outer space exploration overweigh its disadvantages.With the rapid development of the industry,the environment we are living in now is becoming worse and worse,besides,the resources on the earth is is exploited excessively.So outer space exploration is of great significance to us.
