Welcome to Worth Magazine’s first-ever Sustainability Issue! This magazine reflects our growing understanding that as the world changes, business must change with it. There are new constraints on extractive industries, some by government regulation, but others by consumer demand. Right now, everyone from the nation’s leading financial advisors to consumers at the grocery story are making decisions based on sustainability. All businesses, and business leaders, will have to adapt. In this issue, we chose winemaking as a model for sustainable agriculture, green manufacturing, and consumer product marketing.
