36、continued Listening 1 Doreen:Sure.Mom,I think Im going to take a walk.Lara:All right.Narrator:Plants and animals are protected here;first,because the Tsingy is a national park,but more importantly because its almost impossible for people to go there.The name of the park means,“place where one cannot
37、 walk barefoot”,and in fact,you need more than a good pair of shoes to enter the Tsingy.The stone peaks at the top are almost as sharp as knives.Down below in the deep canyons,there are caves and water to deal with.This is no place for the casual tourist.On the other hand,this dramatic landscape is
38、an advantage for the plants and animals that live in the Tsingy.Here white lemurs can easily jump from peak to peak,looking for trees in the canyons below and eating leaves.Insects,lizards,and frogs live here,too,To be continued Listening 1 and all of them are free from the effects of human beings.L
39、ara:Youre back already?Doreen:Yeah.Its raining.Narrator:In other ways,however,the lack of people visiting the Tsingy is a problem.Tourism was once a very important part of Madagascars economy,but political violence and other problems now keep many tourists away,and in the Tsingy,the rock formations
40、are simply too difficult for most tourists to reach.Without tourists,there is a lack of money coming into the region.That means little money for research,so scientists arent sure how climate change,for example,is affecting the Tsingy.There is still much to learn about this fascinating place.Listenin
