Tourism supply relies on many interconnected factors including natural resources, transportation, accommodations, attractions and activities. It is a composite product made up of various components that may be purchased separately or together. Local governments play an important role in tourism supply by providing infrastructure, visitor attractions, information, environmental stewardship and support for economic and social development. The private sector includes small businesses and large companies, while the not-for-profit sector focuses on conservation and protecting natural and cultural assets without a profit motive.
