With all the problems in the world, spending money on space exploration is a complete waste or not? Today we have a lot of problems on the world: famine, global warming, armed conflicts in Asia, Africa and so on. With all of these serious issues on the planet, we need to think about this important question: is it reasonable spending money on something like space exploration? Some people maybe say there is no simple answer for that. I understand them but in my opinion the true answer is: No and Yes! It depends how we are going to spend this money. Why should we spend money to find some black holes or stars in very far away at others galaxies. It is completely waste of money because this kind of explorations make no positive differences on our life. For example, NASA discovered a gas giant is 13000 light years away from the Earth in 2015. It is a historical record for NASA but what is the point of spending money and time for finding someplace you can never go or even if someday human can go that place there is no logical reason for going there?! So what should we do about these expensive programs? I think we can determine some practical goals for space exploration so focus on them and make real positive changes on human life which one of them will discuss in following. The global human growth amounts to around 83 million annually. The global population was 7.6 billion in 2017. It is expected to keep growing and put the population at 8.6 by middle of 2030. It means we are going to have much more problems for providing basic needs of human like food or water in the near future. So if space exploration programs focus on finding new planets could support life, It is helpful for making better life or even surviving next generations. In summary, we should care about real problems on the earth so if we are going to continue space exploration programs, it should be the way make positive impact on human life.
