Only a few decades ago, renovation was unpopular and generally far more expensive than taking down abandoned building and string from the beginning.A change began in the 1960s with a number of well-advertised projects.They included Ghirardelli Square in San Francisco, where an old chocolate factory was restored and made into shops and restaurants, Trolly Square in Salt Lake, where unused warehouses were made into artists’ studios and apartments. What caused the change？ “One reason is nostalgia,” a San Francisco builder suggests.“Maybe old is better than new, many people are saying.Feelings about preserving attractive or historic buildings have changed a great deal.” A second cause is economy.The cost of tearing down an old building and constructing a new one from nothing now has risen to the point where it is often less expensive to fix a solid older structure.Also builders realize that fixing up an existing building often requires no new permits, sewer lines, or water connections. Even when the costs of restoration are the same as or a bit more than the costs of putting up a new building, fixing the old building may be better.A Boston architect says The advantage comes when you can develop a final project that is more desirable than a new building – one with the right location, more space, more floor area, a special character, materials of a particular quality.” Gradually, architects and builders are developing knowledge about renovation and preservation, bringing imagination and creativity to the job. 16.In the United States, renovating old buildings_____.

During the past 200 years the world population has increased 6 times, the annual world output has increased 80 times, and the distance a person can travel has gone up 1,000 times. There has also been much recent progress in art, culture, learning, and science. Such changes have led to a high rate of production and growth of the economy. Economists fear that within the next 100 to 150 years, the earth's resources will become very scarce. Their fears are partly justified, but we should not be afraid. Industrial civilization adapts to new knowledge. By advancing knowledge, we not only create new forms of resources, but we also find ways to economize their use.
