By January 2015 the world‎'‎s richest 80 people had as much wealth as the poorest 50 per cent of the world‎'‎s population‎.‎ It is a global unevenness through which the barriers to in‎-migration of Third World migrants to wealthy First World nations go ever higher‎,‎ while the barriers to travel in the reverse direction are all but extinct‎.‎ So how exactly does tourism contribute to narrowing this glaring inequality between the rich and poor‎?‎ Are ever‎-expanding tourism markets a smoke‎-free‎,‎ socioculturally sensitive form of human industrialisation‎?‎ Is alternative tourism really a credible lever for reducing global inequality and eliminating poverty‎?‎ Tourism and Sustainability critically explores the most significant universal geopolitical norms of the last half century ‎- development‎,‎ globalisation and sustainability ‎- and through the lens of new forms of tourism demonstrates how we can better get to grips with the rapidly changing new global order‎.‎ The fourth edition has been extensively revised and updated‎,‎ and benefits from the addition of new materi‎.‎‎.‎‎.‎
