Tourism involves traveling to places outside one's usual environment for leisure, business, or other purposes for no more than one year. It provides communities opportunities to showcase their unique culture and nature while creating jobs and diversifying their economies. Visitor spending injects new money into local economies and is re-spent, creating a multiplier effect. Tourism also creates many employment opportunities, encouraging young people to stay. While tourism benefits economies and societies, it can also harm the environment if not managed sustainably.
