Exercise 9. Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions. 
 Tourism will always have an impact on the places visited. Sometimes the impact is good, but often it is negative. For example, if lots of people visit one place, then this can damage the environment. The question is - how can we minimize the problems without preventing people from travelling and visiting places? 
 The main aim of ecotourism is to reduce the negative impact that tourism has on the environment and local people. The idea is to encourage tourists to think about what they do when they visit a place. 
 It's great to talk about protecting the environment, but how do you actually do this? There are a number of key points. Tourists shouldn't drop litter, they should stay on the paths, they shouldn't interfere with wildlife and they should respect local customs and traditions. 
 Some people see ecotourism as a contradiction. They say that any tourism needs infrastructure - roads, airports and hotels. The more tourists that visit a place, the more of these are needed and, by building more of these, you can't avoid damaging the environment. 
 But, of course, things aren't so black and white. Living in a place of natural beauty doesn't mean that you shouldn't benefit from things like better roads. As long as the improvements benefit the local people and not just the tourists, and the local communities are consulted on plans and changes, then is there really a problem? 
 In 2002 the United Nations celebrated the "International Year of Ecotourism". Over the past twenty years, more and more people have started taking eco-holidays. In countries such as Ecuador, Nepal, Costa Rica and Kenya, ecotourism represents a significant proportion of the tourist industry.

Exercise 10. Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions. 
 Ecotourism is a unique way for travellers to engage in sustainable tourism while vacationing. Throughout the years, specific "Eco" organizations, including Eco-resorts, wurs, and Non-Governmental Organizations, have developed across the globe. This specific type of tourism is now increasingly becoming one of the more popular, with growth rates increasing every year. The United Nations, aware of the fact that tourism could be one of the most detrimental activities if not planned in accordance with the threshold imposed by nature, has declared the celebration of the International Day of Ecotourism, to promote sustainable practices in this growing industry.
 Recently, The Division for Sustainable Development, Small Island Developing States Unit, decided that in preparation for the International Day of Ecotourism, it would be beneficial to identify successful practices of ecotourism on small islands. In order for ecotourism to be categorized as successful, it must meet the following criteria: it must combine natural and cultural tourism; it must involve local populations in the program, including providing educational resources to the local community; it must identity, manage, and conserve the natural and cultural environment, as well as the resources on the island; it must generate practices that will lead to the future sustainability of the island. If these criteria are followed by an organization, it deserves to be recognized as successful.
 In order to locate these certain organizations, the SIDS Unit started a thoughtful internet search for ecotourism organizations. The focus was on four different categories: Eco-resorts and hotels, Eco-tours, Non-Governmental Organizations involved in ecotourism, and Government Codes of Conduct and Guidelines regarding ecotourism for travellers. Once an Internet-site that filled the criteria was located, further contact with the organizations was initiated, enabling us to obtain further information directly from the source. Many of the organizations were delighted to correspond with us and are eager to show all that their organization has achieved. 
 The stories presented come from across the globe and vary in success levels. While all of the organizations engage in practicing ecotourism, some focus in different areas than others. This is due to a various number of reasons, including the size of an organization, length of time the organization has been in existence, amount of funding available, and economic/political situations occurring on the island. However, it is important to recognize that although some ecotourism organizations are more developed than others, the ultimate goal of sustainable development, conservation and education through ecotourism remains consistent.
