In the future, it seems it will be more difficult to live on the Earth. Some people think more money should be spent on researching other planets to live on, such as Mars. To what extent do you agree or disagree with this statement?

There is a view that
people
should invest more in searching for other livable planets because it looks like living on
Earth
is increasingly challenging.
This
essay will explain why I disagree with
this
view via a discussion of the feasibility of continuing to stay on
Earth
and the challenges of multi-planet travel. To start with, it is not certain that life on
Earth
would be more difficult. The reason for
this
is there are still a lot of resources,
although
they are depleting, and humans still do not utilize all the land.
Therefore
, it would take quite a long time before the need to relocate to another planet becomes obvious.
Furthermore
,
people
are aware of the decline of resources and are focusing efforts on recycling.
For example
, there are many campaigns promoting saving water and stopping wasting food. Industrial companies
also
start using renewable energy sources,
such
as wind and solar power.
Secondly
, travelling from one planet to another is not easy or straightforward.
This
is because, currently,
people
do not have enough technological advancements to make
this
kind of expedition efficient.
For instance
, a journey from the
Earth
to the Mar takes around seven months and is carried out by machines and robots only. If
people
were involved in
this
journey, scientists would need to sort out many related problems,
such
as storing food for a long time and keeping humans in good shape in space.
Moreover
, researching these technologies
also
poses an enormous financial burden, for which the world is not quite ready, given many urgent social issues that need to be looked after. In conclusion, I believe that it is possible to have life on
Earth
sustainably by employing green power sources as well as reducing waste.
Also
, because space travel is costly and complicated,
people
should spend their money prudently.
