There are no foreign lands. It is the traveller only who is foreign.
Robert Louis Stevenson
Tourism is one of the world’s largest industries, contributing over US$7 trillion to the global economy, nearly a tenth of global GDP, and accounting for 1 in 11 jobs on the planet.
The number of international tourist arrivals per year is now well over 1 million.
Tourism can bring economic benefits to host regions, and social and cultural benefits to hosts and travellers alike. Many countries, such as Nepal, rely on tourism as their primary source of income. But the industry can also bring problems including social disruption, economic imbalances and severe environmental impacts. For example, in places such as Bali and Goa, tourist resorts use huge amounts of water, creating water scarcity for local residents.
Moreover, jet travel especially has a heavy impact on global warming due to emissions of carbon dioxide and water vapour.
To counter these negatives there is now a growing focus on ethical and environmentally sustainable tourism, which requires a shift in values and awareness on the part of tourists as well as tourism operators.
