This chapter addresses structural and social solutions to the challenges of overpopulation and consumption. Greening an existing business requires a different way of thinking and a different way of conducting commercial activities. The efforts to encourage sustainable living depend on structural changes that require political and corporate leadership. A sharing economy, also called collaborative consumption, involves the new sharing that reduces waste, saves money, and becomes more self-sufficient, all without buying more stuff. Environmental impact is the extent to which certain actions or behaviours change availability of certain resources or energy in the environment or alters certain structures and dynamics of ecosystems. Socially responsible investing steers capital towards companies or projects that generate positive, measurable social and environmental returns. Industrial symbiosis encompasses a network of producers, suppliers, and clients that can foster eco-innovation and social change by continuously sharing mutually profitable transactions and improving technical processes that enable continuous material flow.
