The second challenge: Like any other mineral processing industry, production of steel results in a net depletion(用尽) of non-renewable resources of ore and energy and leads to an irreversible degradation (退化) of the global environment. Apparently, this cannot go on for ever. The steel industry must harmonize itself to the needs of both the current generation as well as those of the future, and devise ways to transcend the ecological limits on growth.
The third challenge is the ability to change. Change is a time-tested mechanism for growth, and the ability to change is the hallmark of successful organizations. The steel industry with its large capital investments and long product development life cycles, finds itself very often out of accordance with global trends. The industry in general and individual plants in particular, must reengineer their technological operations, and become flexible enough to manage change, cope with uncertainty and thrive in a dynamic environment.
The image of steel has become one of a sunset industry, which in turn deters(阻止) the best and brightest brains in the land from making a career in iron and steel. If not today, then very shortly, we are heading for an acute scarcity of new ideas with which to overcome our current problems. This is the final and perhaps the most difficult challenge. We must improve our image. We must motivate and assemble the best talents to our cause, if only to have the money to meet all the other challenges which we are facing.
The big potential steel market is ______.
A．in industrialized countries
B．in agricultural countries
C．in Asia, Africa, and South America
D．in European countries

How were you able to come to China in 1979 and study？
I earned my degree in economics and Chinese studies. At the end of university, 12 students were' selected to do a postgraduate program in China in 1979. I think I was chosen because I have a good wuchanjieji (proletariat) class background. I was sent to Nanjing Normal College.
Looking back, what does that experience mean to you？
I stayed for nearly 18 months in Nanjing. I find the experience valuable for me. When I sit with a Chinese official or a partner who is 50 years old, I understand what his life was like because I was there too. I feel like I can quickly get to a point where we feel like we have something in common. To me it's the biggest advantage.
So does it feel like you have never left China？
Yes. After studying in Nanjing, I decided to stay in Asia and went to Taiwan for a while to formalize learning Chinese. I came back to the Chinese mainland hi 1980 and have been involved in negotiations and the founding and running of several of the country's first joint ventures (JVs), including two in the transportation industry.
JVs are not easy. Why do you seem to have the knack for successful JVs？
I'm lucky. I had no work experience in Australia, all my work experience is in China. The way I work leans towards the Chinese way. I tend to focus on relationships and try to build up a consensus on what we want to do.
You had a rock band, one of the earliest in China. Tell us about that？
I always played guitar for fun. In the second half of 1989, we didn't have much business, so my friends and I made a band consisting of the five of us. We played part-time in the bars. The biggest concert was during our tour of Mongolia where there were about 7,000 people in the audience. We were on CNN and things like that. The band lasted for three years and I haven't played much in recent years as I'm busier and have a family.
From rock band to rocks -- the corner stone of BHP Billiton is rocks, in its original sense. What's so exciting about the rock business？
Look around and you'll see that everything is either grown or mined. I like being in an industry that's essential and really creates wealth and adds value.
What is your business in China？
The bulk of our business-in China is sales and we don't have too much investment at the moment. We sell iron ore, aluminum, steel and other products.. BHP was the participant in the first offshore oil contract signed in 1979. Offshore oil exploration in China cost us about US$200 million between 1983 and 1996. We were also the first major foreign company to invest in mineral exploration in China. From 1991 to 2000 we had five joint venture exploration companies. Also during that period we invested about US$23 million into two wholly owned steel fabrication factories.
Has your offshore and mineral exploration been worthwhile？
We did a lot of oil exploration, but didn't find anything. Our five exploration IVs also didn't come up with anything. That's the nature of the mineral business and we accept that. Typically in our business we might have 1,000 exploration projects for one commercial
