Nowadays, in the world, billions of dollars are used for space exploration projects yearly. Almost people agree with this because these research have been obtained lots of successities. But some people suppose that, the money which is used for space discovery projects should be used to solve problems on Earth. It is more practical for living.
It can be seen clearly that many developed country invest a great number of money in space research projects. For example, USA spends just over 130 billions dollars on space discovery yearly, or Russia also expends over 90 billions dollars and many many advanced countries in the world. This a large of money were used mainly for research outside the Earth. They want to explore another planets where possiblly exist lives, they are going to find the answer for the question: " How is the Earth construct originally?"... generally these projects's results give us the mainpulaion of the Earth in manner. And acording to most people, The successities of these research will be very useful for living in the future.
However, these projects are not always accepted, other people suppose that a large number of money shoule be used to solve some problems on Earth rather than to invest in space research. For them, there are a mount of hard problems need money to solve such as creating better infrastructure or fighting against invironment pollution... furthermore, money were spent on space discovery projects is so much. As in a given report, the cost for building a discovery plain can save billions of people living miserably. They believe that it will contribute more directly and more practically.
In conclusion, there are two positions oppositely about whether or not better to invest money on universary study or solving social problems. Each own has many persuadsive reasons but for me we should still use money to discover planets. That is the way we open knowlege to higher level and this is also very useful for living after.
