In recent years, there have been more and more cou Essays In recent years, there have been more and more countries involved and interested in long-term space projects. Because of the enormous research expenditures incurred, the value of space 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 space ambition, one should adopt a broader perspective. The investment in space research can be paid off someday in the future.The first reason to support it is that our planet 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, such 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 space research is a promising adventure.Meanwhile, the world's population is now growing to a stage where there are too many people for the planet to support, highlighting the need to seek land suitable for people's resettlement off the planet. Even if new urban developments are able to accommodate the increasing population, water and electricity supply, waste treatment, sewage disposal and sanitation will become unmanageable for the capacity of our planet. As there are countless planets orbiting stars throughout the universe, one can be confident that at least one of them is suitable for our second home planet Mars, for example, bearing a close resemblance to the Earth, is considered a potential backup.In addition to searching for a shelter for future generations, space programmes contribute considerably to the well-being of the Earth in some other aspects. For example, by monitoring the ozone hole, global warming, the loss of rain forests and other environmental threats to human survival, remote sensing satel lites help people trace the recovery from the worst environmental threats and thereby improve the quality of life. Meanwhile, space research provides a new platform on which scientists can carry out experiments and make new discoveries in a variety of fields, such as agriculture.As suggested above, in locating new resources, positioning new settlements, addressing environmental concerns and facilitating scientific discovery, space research will prove to be not only worthwhile, but also crucial to the survival and sustainability of human civilization.
