Teacher: Do you think that governments spend too much on space exploration nowadays?

Student: Well, I think that there are a lot of different factors to take into consideration. For example some countries want to show the rest of the world that  are successful and  can do this with a space exploration program.  seems that  is more important for these countries to impress the world than to look after their own people. Sometimes  is difficult to understand this because every country in the world has  problems and has poor people that need to be looked after because they can't look after  . So, yes, I do think that these countries should look after people first before  start trying to send men to the moon!  are too many other problems here on earth that we need to sort out.
