good afternoon, ladies and gentlemen. today i would like to begin with a story.
there was once a physical 1) therapist who traveled all the way from america to africa to do a 2) census about mountain 3) gorillas. these gorillas are a main attraction to tourists from all over the world; this put them severely under threat of 4) poaching and being put into the zoo. she went there out of curiosity, but what she saw strengthened her determination to devote her whole life to fighting for those beautiful creatures. she witnessed a scene, a scene taking us to a place we never imaged we've ever been, where in the very depth of the african rainforest, surrounded by trees, flowers and butterflies, the mother gorillas 5) cuddled their babies.
yes, that's a memorable scene in one of my favorite movies, called gorillas in the mist, based on a true story of mrs. dian fossey, who spent most of bet lifetime in rwanda to protect the ecoenvironment there until the very end of her life.
to me, the movie not only presents an unforgettable scene but also acts as a 6) timeless reminder that we should not develop the tourist industry at the cost of our ecoenvironment.
today, we live in a world of prosperity but still threatened by so many new problems. on the one hand, tourism, as one of the most promising industries in the 21st century, provides people with the great opportunity to see everything there is to see and to go any place there is to go. it has become a lifestyle for some people, and has turned out to be the driving force in gdp growth. it has the magic to turn a backward town into a wonderland of prosperity. but on the other hand, many problems can occur---natural scenes aren't natural anymore. deforestation to heat lodges is devastating nepal. oil spills from tourist boats are polluting antarctica. tribal people are forsaking their native music and dress to listen to u2 on walkman and wear nike and reeboks.
