Read the article and select the best answer. Article: There is much discussion today about whether economic growth is desirable. At an earlier period, our desire for material wealth may have been justified. Now, however, this desire for more than we need is causing serious problems. Even though we have good intentions, we may be producing too much, too fast. Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world's population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease. People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization. This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and business community must pay attention to these problems and discuss them with one another. Question: We may infer from the passage that _ . Options: A: the author describes the case as it is B: the author is for economic growth C: the author is against continued economic growth D: the author is very much worried about the problems of continued economic growth
