tourRachel:Dad,Ive been searching online for some information about holidays,as you asked.Dad:OK Rachel.So,whats caught your eye?Rachel:I thought we might go on an ecotourism holiday.The idea is that you go to a natural place and help conserve it.To me,thats much better than just sitting on a beach.Dad:Hmm.Im not sure about that.Rachel:Oh,come on,Dad.The fact is that travel does a lot of harm to the environment.Wouldnt you agree that we should do something positive?Dad:If you ask me,lying on a beach is doing something positive!OK,where do you want to go?Rachel:Well,theres is a holiday to Nepal.It looks fantastic.You get to hike in the mountains and plant trees.And you get to count rhinos to help protect them.Dad:Wait,what?There are rhinos in Nepal?Rachel:Yes,Dad!You also eat simple local food,like rice and vegetables.Thats real ecotourism.Dad:Rice and vegetables?I can eat that at home!And I dont think hiking up mountains and planting trees are very relaxing.I would say they sound like hard work!Rachel:Yes,thats true.OK.Lets find a compromise so we can both be happy.How about Thailand?We can look after elephants and sleep in a treehouse.Dad:Look after elephants?What would we have to do?Rachel:Well,we would have to feed them three times a day.In the afternoon,you wash the elephants.Oh,and you also have to play with them-you can swim in a river with them or play with baby elephants.Apparently the older elephants can play a kind of football!Dad:I admit that sounds rather fun.Rachel,is this holiday near the coast?Rachel:Yes,it is.Dad:Then lets meet in the middle.As a compromise,how about we stay nearby in a nice hotel?You can do some ecotourism activities while I lie on the beach and read a book.Then were both happy.Rachel:So I can look after elephants?OK then,I agree,but we both have to go on a one-day bike tour of the jungle.Dad:Fine,its a deal.P67 Activity8 Complete the passage with the expressions in the box As tourism develops,people are becoming
