apidly. They are no longer restricted by their environment, as they can live in the most hostile of deserts or the bitter cold of Antarctic.Human culture is heavily based on the earth's natural resources -- oil, coal and metals; soil, water and forests. Industrialized society is using increasing amounts of these resources each year. Governments and industrialists strive for economic growth -- for factories and mines to produce more each year than they did in the previous year. But fuels and metals and, to a lesser extent, the soil are nonrenewable resources. Once used they are gone forever. In many cases the lifetime of these resources is coming to an end.Factories and machines create wastes. These wastes are poured into the atmosphere, the water and even into the soil. The damaging effect of this pollution is, in some cases, permanent. To reduce pollution creates further problems. Factories may have to be redesigned or even pulled down. This costs money and may mean loss of livelihood (生计) for many workers.Modern technology is creating an additional problem -- it is making industry more and more automatic (自动化 . This means that fewer and fewer people are needed to operate factories and offices. The consequent loss of jobs is a worldwide problem and western society is still struggling to find the answer.This introduction gives you some idea of the topics to be discussed in detail in this chapter.

business with no food industry experience. "We wanted to make the best gelato in the world and we didn't know how to make any gelato!" Fed recalls. That did not stop them though and the business has become more and more successful.

The word gelato means "frozen" originally. Since ancient Rome, people have been enjoying cold desserts. Many think gelato is just an Italian name for ice cream. But actually it is a different product. According to Fed and Guido, the difference between ice cream and gelato is the amount of fat in the product. In ice cream you have an average of 17-18% of fat, but with Italian gelato you have 10%.

It was Guido who first came up with the idea. He thought that if they got the best materials, they could make top quality gelato. Fed then put a business plan together and the two decided to go for it. The only rule they had when they started out was to stick to their guiding principle—to try to create the world's best gelato. Their efforts paid off. Sales of their gelato have doubled in Italy every year since 2008. It outpaced （超过）the growth of every other type of iced dessert by some way. The company grows from two employees in 2003 to nearly 700 employees today.
