I am convinced that humans need to leave
earth and make a new home on another
planet a stay risks annihilation that
could be an asteroid hitting the earth
that got me a new virus climate change
nuclear war
artificial intelligence gone rogue for
humans to survive I believe we must have
the preparations in place within 100
years
but we're next
our species has evolved to live on earth
so our new home must be very similar it
must be a similar sized rocky planet
with similar gravity it must have an
atmosphere with just the right amount of
oxygen and crucially it must be the
right distance from its star that water
exists as a liquid the journey of two
thousand years isn't impossible we
present spaceships where successive
generations live and die in space that
might not sound Pleasant
but there's what me the sacrifice for
the furthering of our species their
descendants would be the ones who
ultimately colonized Proxima be many of
the reasons I think humans need to leave
the earth are down to the way we have
used technology pollution climate change
and even overpopulation spring to mind
in the next 100 years we will embark on
our greatest ever adventure our destiny
is in the Stars space here we come for
me it's not a question of whether we
will become an interstellar species but
only a question of when
you
