This
Linking Words
essay will explain why I disagree with
this
Linking Words
view via a discussion of the feasibility of continuing to stay on
Earth
Use synonyms
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

start using renewable energy sources,

kind of expedition efficient.
For instance

people

were involved in
this

journey, scientists would need to sort out many related problems,

Also

, because space travel is costly and complicated,
people

should spend their money prudently.
