According to Beaver, “tourism is the temporary, short term movement of people to destinations outside the places where they normally live and work, and their activities during their stay at these destinations; it includes movement for all purposes as well as day visits or excursions” (313). Beaver argues that tourism arises from a number of factors (313). “Tourism arises from the movement of people to and their stay in, various destinations” (Beaver 313). Tourism is made up of two major components: “the journey to the destination and the stay including the activities at the destination” (Beaver 313). Usually, the journey and the stay take place in an area that is different from the normal place of work or stay. As a result, tourism gives rise to activities which are different from those done while at work or at home. On the other hand, “Dickson defines ecosystem as a community of living organisms with the physical processes which occur within an environment” (2). Ecosystems often interact in a variety of ways through their biotic and abiotic components. Ecosystems often encounter stresses imposed by human activities and physical environments. In addition, they encounter changes which may be caused by human activities. An example of human activities which cause changes in the ecosystem is tourism. One of the most difficult problem facing environmental scientists is diagnosing the nature of environmental change. Not only is the extent and rate of change often hard to detect, and even harder to predict, but it may also be very difficult to distinguish between those components of change which are part of a natural process and ecosystem dynamics, and those which are as a result of human impacts. Yet unravelling all of these issues is vital if ecosystem function is to be sustained and irreparable damage to the biosphere avoided. This paper attempts to analyse the impact of tourism on the ecosystem. According to Bio Intelligence Service, “people are great consumers when on holiday” (1). Recent studies have indicated that the ecological footprint in some parts of the world is almost same as that of residents. Bio Intelligence Service notes that, when arrival transport account is put into consideration, this ecological footprint escalates. Tourism forms the backbone of many economies around the globe. However, it has been found to exert indirect and direct pressure on species and habitats and, as a result, it poses a significant threat to conservation. Furthermore, tourism often disturbs wildlife and heightens environmental pollution due to increased transportation of people. The negative impacts of tourism on ecosystem are aggravated by the fact that tourists tend to consume more than the local communities. In addition, tourists tend to consume more when they are on vacation. A study was conducted recently in Val di Merse, Italy, to determine the ecological footprint of tourists in this region. This study found out that Val di Merse receives a total of 685 tourists per day. As a result, the local population is increased by 5 percent. The researchers “gathered data on arrival transport, on food and fibre consumption, on accommodation, on land use, utilities and waste, on local transport and on activities of tourists on holiday in Val de Merse region” (Bio Intelligence Service 1).
