Should mankind invest in exploration of space?

My husband and I have this argument a lot. He believes that space should be explored but not if we have to sacrifice the resources that could be put toward our problems that we have back on earth. In truth he has a good point, however I still tend to take the opposite view. I believe that space should be explored but it should be done in a responsible manor. Currently right now there are hundreds of technologies and medical devices or procedures that have come about because of our involvement in space, including inventions that help fight disease and world hunger. Humans greatest inventions have always come out of it's necessity and the exploration of space forces the necessity upon us. Lastly, that which can not be measured, space has inspired human beings since we could first be considered human. The now reachable stars have filled the dreams, imagination, and aspirations of millions of children and more than a few adults. This is something that can never have a price on it, and it spite of the ever evolving list of problems that humans will have, space exploration shouldn't be something that is too be taken away in order to help solve those problems. Instead it should be ever more pursued, with the hopes of accomplishing the same goal.
