Indeed, a rosy picture is painted for the long-term future of the holiday industry. Every month sees the building of a new hotel somewhere. And every month another rock-bound Pacific island is advertised as the “last paradise (天堂) on earth”.  However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy.
