The tourism infrastructure significantly contributes to the release of greenhouse gases in the atmosphere, that trap heat from the sun causing the steady increase in the Earth’s surface temperatures in recent years known as global warming. One of the most significant of these gases is carbon dioxide (CO2), which is generated from the use of non-conventional sources of energy, such as coal, oil and natural gas for many tourism related activities. The aviation industry is an essential element of Cancun’s tourism and also a major contributor to the greenhouse effect. Moreover, the number of international travelers is expected to be increase significantly in upcoming years. The abnormal changes in land use and deforestation can also contribute to the global warming. In a long run, global climate changes have posed a significant threat to the existence of the life on the planet earth (Castillo, 2005).
The maintenance of tourism infrastructure involves extensive use of refrigerators, air conditioners; responsible for the emission of ozone depleting substances (ODSs) such as CFCs (chlorofluorocarbon) further causing the depletion of protective ozone layer. The considerable amount of potable water is being consumed by tourism industry. The state of Quintana Roo depends almost entirely upon ground water for its potable water supply (Pérez and Carrascal, 2000). The heavy use of this resource will lead to the saline intrusion of aquifers which will render them virtually useless as a source for potable fresh water. Further, the decreased amount of water being available for the use of natural ecosystems will result in ecological imbalance.
