Environmental impacts of tourism on Los angles

you are required to find 4 articles on the environmental impacts of tourism on a destination of your choice. You are free to select any destination in the world (a community, town/city, province/state, country or region).
For instance, for your first paper, you could decide to focus on the island nation of Jamaica. Your next step would be to find four separate readings on the socio-cultural impacts of tourism on Jamaica.
The articles you select for each of your papers must be:
1) one from a scholarly journal;
2) one from a professional periodical (trade publication);
3) one from a book (can be a chapter) but NOT your class text;
4) one from any other source (journals, trade publications, books, magazines, newspapers, etc)
