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

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 re-settlement of 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 satellites 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 civilisation.
