First of all, it is obvious that the study will provide us more knowledge on other planets in terms of environment, lives and biology. Such knowledge might be further leveraged into the studies on different subjects, such as genetic engineering, power & energy generating and out space utilization. Human on the earth can eventually benefits from those study outcomes.
Secondly, the out space travel might entertain the increase curiosity from those with open-minded, seeking more exposure to other planets. Thus, it could not only appeal to those potential travels also foster the economic growth on stylized travelling.
Furthermore, with strong pollution as well as significant increasing of population, the earth might not to an ideal place for people to live in. Consequently, even might not be able to afford so many human beings. In this case, some plants offer similar living environment would be a choice to release the burden on our earth.
In spite of above mentioned benefits, there are still lots of uncertainties on space study. For example, the outcome from the study might not be able to transfer to applied technology, which is used to improve people’s lives eventually. Besides, the out space is far away. It is risky to send people to the plants once anything happens and gets out of control.
All in all, I believe the out space study is worthy as to get more knowledge and resources that could leverage into our lives on earth. However, there are uncertainties and risks that need to be addressed.
