Despite being one of the most important tourism sectors for the economy, generating jobs, income, contributing to local development, among others, the problems caused by this activity cannot be omitted.

This work provides support for entrepreneurs and managers in the tourism sector, it is also aimed at researchers and academics of the tourism course who can use as references and expand the theme. In addition to sensitising tourists and the general public about these negative impacts and what can be done to avoid them and allow tourists to continue enjoying their holidays without pollution.
