Read the following passage and answer the questions.

Travel and tourism are very important to millions of people over the world. In every country you can find people that work in travel and tourism. Some countries need the money from tourism to help their people survive. It is necessary for these places that travel and tourism continue to expand and bring money to their regions.

However, travel and tourism have negative aspects. Planes, buses, boats and other means of transportation that carry travellers and tourists cause pollution. Moreover, some people do things on a holiday they would never think of doing at home. For example, many travellers use lot of water and electricity when they stay in hotels. They forget to turn off the lights or even leave televisions and air conditioning units on when they leave the room. On top of that, it is often difficult or impossible for travellers to recycle items, so they end up leaving large amounts of waste behind. That's why it is important for people to travel wisely and respect the places they visit.

1. Don't throw rubbish on streets, beaches or in the countryside.
