Tourism is booming internationally. Latest annual figures show 1.32 billion tourists roaming the globe – 84 million more travellers than the previous year.
Those travellers are boosting local economies everywhere, but they are also creating problems with too many tourists visiting too many places at the same time.
Australian Chris Flynn is head of the newly formed World Tourism Association for Culture and Heritage, which aims to protect local cultures, heritage and historical sites that are now at risk from over tourism.
A major concern is the impact the cruise ship boom is having on remote island communities, as well as on major cruise ports where thousands of passengers disembark daily for land tours.
Here Chris, who has spent 40 years working in tourism and aviation, most recently as director of the Pacific Asia Travel Association, voices his concerns to Veronica Matheson.
