Tourism : our impact on the planet

From beach resort package deals to African adventure holidays, more and more people are spending money on travel.

Tourism has become one of the world's largest and fastest-growing industries, creating enormous wealth but also causing serious environmental, cultural and economic problems in destination countries.

As tourists increase in numbers and venture into ever more remote locations, such negative effects seem set to get worse - unless urgent action is taken. "Tourism" examines the most pressing issues affecting the industry.

Is it advisable for less developed countries to base their economies on tourism? And how can tourists themselves make more responsible, informed choices.

Opposing viewpoints are given throughout to provide opportunities for discussion and debate.
