Millions of dollars are spent on space research every year. Some people argue that the money should be spent on improving living standards on Earth. Do you agree or disagree

In recent years, there have been more and more countries involved and interested in long-term

expenditures incurred, the value of

projects has been disputed. Some people suggest that government funding should be diverted toward improving the living standard of ordinary people. In evaluating the merits of

ambition, one should adopt a broader perspective. The investment in

can be paid off someday in the future. The

reason to support it is that our

is now facing an unprecedented resource problem, which can be tackled only by discovering and mining new resources on other planets. The overuse or scarcity of some resources on the Earth is a severe problem. Rare metals,

as gold or silver, will eventually be depleted, as industrial production expands. These metals and other natural resources,

although

rare on Earth, might abound on other planets. In that case, conducting
