In terms of the planet's resources, stewardship would simply entail taking care of what one has, whether an individual, family, company, or government. Now we come to the crux of the problem, being the aforementioned. Everyone is different and there is no common agreement in regard to "the needs of the people."
In thinking stewardship, fashion takes a back seat. In developed nations, fashion is part of success. Since each nation and government is divided into sections of differing cultures, we can view the United States as a good example of where stewardship takes on different meanings; The region of the Pacific Northwest carries the trophy for being ecologically aware, having begun some of the nation's first recycling programs for glass, aluminum and plastic back in the '70's. One part of stewardship is responsibly disposing of waste, and as the population grows, so does waste. The term, "reduce, reuse, recycle" abounds in stewardship thinking.
Stewardship is a big inconvenience. It means we must think about what we do, what we use and how we get rid of it.
