Until the very latest moment of his existence, man has been
Bound to the planet on which he originated and developed.
Now he had the capability to leave that planet and move 【S1】______
out into the universe to those worlds which he has known
previously only directly. Men have exploited parts of the moon, 【S2】______
put spaceships in orbit around another planet and possibly within
the decade will land into another planet and explore it. Can we be 【S3】______
too bold as to suggest that we may be able to colonize other 【S4】______
planet within the no-too-distant future? Some have advocated 【S5】______
such a procedure as a solution to the population problem: ship the
excess people off to the moon. But we must keep in head the 【S6】______
billions of dollars we might spend in carrying out the project. To
maintain the earth’t population at its present level, we could have
to blast off into space 7,500 people every hour of every day of the
year.
Why are we spending so little money on space 【S7】______
exploration? Consider the great need for improving many aspects 【S8】______
of the global environment, one is surely justified in his
concern for the money and resources that they are poured into 【S9】______
the space exploration efforts. But perhaps we should look at
both side of the coin before arriving hasty conclusions. 【S10】______ [br] 【S9】
