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 serous 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. They 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 the business community must pay attention to these problems and continue discussing them with one another.

某贫困地区领导认为，脱贫不能仅靠政府救济，更要靠自力更生。他们根据其它地区“无工不富”的经验，建起了一些小机械厂，但由于原材料和资金缺乏，结果收效甚微。经过认真分析，他们认识到该地区山场面积大，适宜发展林果业和养殖业，于是因地制宜种起了果树、中药材；饲养起了牛、羊、家兔等，经济情况有了很快的改观。在此基础上，他们又办起了果品和肉类加工厂，几年就摆脱贫困，走上了裕之路。

该地区在脱贫过程中是如何做到“一切从实际出发、实事求是”的？
