Until the very latest moment of his existence, man has been bound to theplanet on which he originated and developed. Now he has the capability to 1 leave that planet and move out into the universe to those worlds which he hasknown previously: only directly. Men have explored parts of the moon, put space- 2 ships in orbit around another planet and possibly within the decade will land into 3 another planet and explore it.Can we be too bold as to suggest that we may be able to colonize other 4 planet within the not-too-distant future Some have advocated such a procedure as 5 a solution to the population problem: ship the excess people off to the moon. Butwe must keep in head the billions of dollars we might spend in carrying out the 6 project. To maintain the earth"s population at its present level, we would haveto blast off into space 7500 people every hour of every day of the year.Why are we spending so little money on space exploration 7 Consider the great need for improving many aspects of the global environment, one 8 is surely justified in his concern for the money and resources that they are poured 9 into the space exploration efforts. But perhaps we should look at both sides ofthe coin before arriving hasty conclusions. 10
