Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.

Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.

Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

Exploration also allows minerals and other potential (潜在的) resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品) of technological developments in the space, the chance to save ourselves might not exist.

While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

I came to India a year ago to find a village in which I could live and write but it was many months before I settled down happily in this Himalayan community.I wasted a lot of time looking for the “typical” village, yet no such thing exists. Conditions vary too widely.But the villages I stayed in had much in common—poverty, dirt, ignorance. Often the villagers themselves were puzzled, suspicious. Why had I come? I had put aside my work as a political journalist because my ideas had changed. I had come to believe that what was happening in the Third World was more important than anything else. But to understand how three quarters of the world’s people live, and how their future might affect ours, I felt that I first had to try and share their way of life.In the end I chose a mountain village because it was a little cooler than those in the plains. I took the bus from town along a bumpy road. Then came a rough walk down a steep path to the river. After this I began the climb into the Mils. Whenever I stopped to catch my breath, there was a magnificent view. After several hours’ walk the village came into view.
