The discovery of an all-water route between Europe and Asia would have lowered prices of Eastern Goods because it would have made the cost of travel and shipping that much cheaper. Travel on land was difficult and laborious. There were huge mountain chains and long journeys to traverse in order to trade goods. An all-water route between Europe and Asia would have made shipping and trading goods a much less expensive venture. If the original price of a jewel in Asia was five dollars, the labor in moving it over thousands of miles of treacherous terrain might raise the price to 15 dollars. If an all-water route were to be found, it would make the traveling of those thousands of miles much cheaper.
4. Man's motives for the exploration of outer space are much the same of the early European's motives for exploration. If people have a good and reliable means of exploring their territory and what they can reach, they will do it. The early European's motives for exploration were many: finding of a Northwest passage, finding new territory to colonize, gold, and the simple yearning to know what is out there that they have not seen before. Man's reasons for exploring outer space and the planets within our solar system are much the same: finding a new planet to colonize, the search for new life, and the desire to see new frontiers.
Although the early Europeans were not really in the search for new life, this is probably because the early Europeans were quite self-oriented, figuring that there was no new life to see, they were it.
