People should definetly invest money in space exploration because it will give us a chance to colonize other planets. This is very important because we live on one small grain of sand suspended in space and we have no more place we can live. Also if some extremely dangerous event occured we would be doomed but if we establish many self-sufficient colonies in different systems we would secure our species from going extinct. The self-sufficiency is crucial here because they will be able to function just fine with our earth being destroyed not habitable any more. This is why I think we should invest money in it.
