Tourism-environment relationships are complex. Thailand economics’ growth based on tourism industries has a very large impact on environment. (Peter mason, 2009) Despite the many negative environmental consequences of tourism that this study identifies, the principal aim of tourism planners and the travel industry is to ensure that high levels of visitor enjoyment are achieved at destinations and attractions because of the financial benefits that arise from this. However, many people often criticize tourism for its negative impacts on the environment and on the nature of the places. Take my home town for instance, it used to be well-known for its beautiful and extensive beaches and people like to go swimming in the sea and enjoy seafood at some restaurants near the beaches. However, because many tourists carelessly throw rubbish like plastic bags into the sea, many marine creatures have died and the place is not clean. We have lost our beautiful coastlines and also have less amount of tourist each year. This clearly shows that tourism can cause many bad effects on the environment and on the value of the places.
