42. We do not own the world, and its riches are not ours to dispose of at will. Show a loving consideration for all creatures, and seek to maintain the beauty and variety of the world. Work to ensure that our increasing power over nature is used responsibly, with reverence for life. Rejoice in the splendour of God’s continuing creation.
41. Try to live simply. A simple lifestyle freely chosen is a source of strength. Do not be persuaded into buying what you do not need or cannot afford. Do you keep yourself informed about the effects your style of living is having on the global economy and environment?
40. In view of the harm done by the use of alcohol, tobacco and other habit-forming drugs, consider whether you should limit your use of them or refrain from using them altogether. Remember that any use of alcohol or drugs may impair judgment and put both the user and others in danger.
