However, their secondary objective is clearly one of minimizing any environmental negatives which may accompany economic success. An essential pre-requisite for this is to retain the host community's continued agreement that the tourism-induced changes that may occur to their way of life and the landscape around them are broadly acceptable ones. 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 rubbishes like plastic bags into the sea, many jellyfishes and other marine creatures have died and the place is not as clean as it used to be. 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.
