The following is a letter to the head of the tourism bureau on the island of Tria. "Erosion of beach sand along the shores of Tria Island is a serious threat to our island and our tourist industry. In order to stop the erosion, we should charge people for

According to the letter, it is stated that sand erosion jeopardizes the island itself and its tourist industry. It is recommended to implement a policy to collect fees from people for using the beaches and use this revenue to finance replenishing project to preserve buildings and shores. In addition, it is asserted that this proposal will boost the tourist industry of island in the long run despite the fact that charging fee might irritate some of tourists. The recommendation might be plausible, but in order to assess the credibility of proposal, more evidence should be provided.

Further evidence is needed to corroborate the viability of proposal about boosting tourist industry. Implementing a policy to collect fees from people who use beaches might discourage higher number of tourist than anticipated number, and as a result projected income could not be reached.

To validate the argument, the author must provide more information about the cause of erosion. It is possible that the erosion is attributed to the crowd of people using beaches. Therefore, raising money in this way would not be an effective measure since collecting money would need more users and more users means higher damage to the beaches.

Moreover, the viability of replenishing project should be assessed by examining the effect of implementing this proposal in a large scale. The success of this project in another island in small scale would not be sufficient to substantiate the predicted achievement.

In sum, the recommendation should be validated by providing more evidence about the different aspect of project ranging from finances to implications of this proposal.
