oConstruction of ski resort accommodation and facilities frequently
requires clearing forested land. Coastal wetlands are often drained and
filled due to lack of more suitable sites for construction of tourism
facilities and infrastructure.
oDevelopment of marinas and breakwaters can cause changes in currents
and coastlines. Furthermore, extraction of building materials such as sand
affects coral reefs, mangroves, and hinterland forests, leading to erosion
and destruction of habitats.
Long Term Impacts of Tourism
•Biological diversity is the term given to the variety of life on Earth
and the natural patterns it forms
•It threatens our food supplies, opportunities for recreation and
tourism, and sources of wood, medicines and energy.
•It interferes with essential ecological functions such as species
balance, soil formation, and greenhouse gas absorption.
•It reduces the productivity of ecosystems, thereby shrinking
nature's basket of goods and services, from which we constantly
•The ozone layer, which is situated in the upper atmosphere (or
stratosphere) at an altitude of 12-50 kilometers, protects life on
earth by absorbing the harmful wavelengths of the sun's ultraviolet
(UV) radiation, which in high doses is dangerous to humans and
•Climate scientists now generally agree that the Earth's surface
temperatures have risen steadily in recent years because of an
increase in the so-called greenhouse gases in the atmosphere,
which trap heat from the sun. One of the most significant of these
gases is carbon dioxide (CO2), which is generated when fossil
fuels, such as coal, oil and natural gas are burned (e.g. in industry,
electricity generation, and automobiles) and when there are
