One of the undesirable aspects of tourism development is environmental degradation in destinations. Firstly, more and more natural resources such as water, energy, and soil are exploited due to the increase in visitor numbers, which may lead to the depletion of local resources. Secondly, pollution is also a serious issue making the authorities worried. Obviously, beverage bottles or cans and plastic bags are freely disposed of at the tourist sites, posing a threat to the natural environment. Besides, the growth of vehicles to meet travel demand accidentally triggers or worsens traffic congestion, air and noise pollution in the overcrowded regions. Another bad influence of tourism is the devastation of the wildlife. The habitats of many wild plants and animals have been gradually lost because of building hotels, resorts and recreational zones. In brief, these negative impacts on the environment will be more serious if there are not appropriate measures.

So many places in the world rely heavily on tourism as a key source of income and employment nowadays, however, tourism can also be a source of problems too.  One of the drawbacks of tourism is the pressure on population. For example, the number of  arrival raises the number of people in an area, which causes traffic jams and social vices. Many cities and towns become overcrowded with tourists, their vehicles increase traffic jams as well as air and noise pollution.Besides, tourists consume a lot of local resources such as water, food, energy, etc., which results in many other depressions. Secondly, Things like ancient buildings, monuments, and temples often struggle to cope with the vast amounts of tourist traffic and they suffer wear and tear or damage.. Some areas can be inundated with visitors during busy times, and then virtually deserted for many months. In conclusion, the development of tourism has both benefits and disadvantages, we need to have the right control over it and prevent the damage caused by tourism.
