There are a lot of serious problems around the world.  Especially depletion of resource is one of serious problems.   Thus we tend to expect to get more resource at another planet and want to spend more money to explore outher space.   However I do not think it good idea.  There is more serious problems to deal with, poverty of developing countries. 

 

  There are a large number of people suffering from lack of food and medicine in developing countries.  If we can send more food aid to such countries and teach them adequate technique or know-how of improving their productive condition with more money, they might not only prolong their own lives but manage their own industry without other countries' support.   Although it would take much time for them to be an substantially independent country, it is, I am sure, possible thinking about the remarkable recovery of my county, Japan after the second world war.

 

  Space exploration cost not a little money but the possibility  to fail for us to get fruitful result is high.  Many space scientists have researched outer space for a long lime,  but even now, when our technology is well developed, they can get feasible way to gain resource from outer space. 

 

  Some of us might think that we should respect the slight possibility of successful result from space exploration.  However, what I want to emphasize is that our financial capacity for investment has limitation and people are dying day by day in poor countries.   In short, we have no room to spend money investing uncertain things such as exploration of outer space as long as poverty is actually solved  Therefore, I cannot agree with the idea that space exploration should be promoted instead of using money for tackling several problems like poverty.
