THE GOOD TOURIST GUIDE
Read holiday leaflets before you choose which agency to travel with. Do they
say anything about environmental problems? If not, ask your travel agent for
advice.
Find out about the country you are going to visit. Learn about its customs
and traditions before your trip.
Some tourists take photos of local people without asking permission. In many
countries this is considered to be very impolite.
Try not to waste water and electricity. It can be limited in the country you
are visiting.
Do not buy souvenirs which are made of fur, skin, shells. Not only that tell souvenir sellers why you do not want to buy such goods (they involve
cruelty to animals).
Make notes during your trip. Was your resort polluted? Were the local people
hospitable with visitors? Send a copy of your notes to the travel agency
who organised the tour.
