Read the second part of the text about ecotourism and answer the questions.
As for transportation, ecotourists might prefer a biking or walking tour to a bus tour which may contribute to air pollution. They often avoid travelling on a cruise ship, as a cruise ship is a great source of air and water pollution, with harmful emissions sent into the air and passengers' waste dumped into the sea. A cruise ship might also cause damage to coral reefs and the ecosystem that it travels near.
What about accommodation? Ecotourists choose hotels and tourism companies that hire mainly local staff, as a way to contribute to the local economy. They can also directly benefit the local people by staying in their homes and studying local traditions.
What else makes tourists become ecotourists? Ecotourists take part in activities or projects to protect the local environment, such as recycling used products or cleaning up the beach. In general, if they make their trip environmentally and socially responsible, they are ecotourists.
