Is travelling dangerous? when we read about famous travellers, we often admire those brave, courageous and resourceful people. travelling has always been dangerous and it will always be. people travelling in the jungle can be strung by mosquitoes, bitten by spiders and snakes or killed by tigers or leopards. in the river they can be eaten by crocodiles, and in the sea – attacked by sharks. it’s logical enough that we try to protect ourselves from our dangerous neighbours. we use different weapons, technical devices and modern technologies against them, which makes travelling much safer. ). loads of cars poison the air, water and earth. planes, delivering passengers from one continent to another, damage the ozone layer of the atmosphere. millions of tons of gas, oil, and coal burnt on the planet for travelling purposes destroy the rainforests and add to the greenhouse affect. ). “ ok, someone can say, what’s bad about that? winters will get shorter and summers will be longer. soon we’ll be enjoying a warmer climate and most people will feel happy about it.” nothing of the kind! the greenhouse effect will raise the temperature slightly, but it will be enough for icebergs and icecaps of the antarctic to start melting. ice melting, in its turn, will raise the ocean level, and some regions, densely inhabited now, may disappear under the water. it will break the balance on the earth, will change the climate, and will drive lots of plants and animals to extinction. ). people are part of nature and can’t escape the global disaster. does everything said above mean that we should stop travelling and should spend our lives in the places where we were born? certainly not. people can’t do without travelling. however, we should consider safer transportation means. safer not only for people, but for nature too. the fragile world we live in deserves love and care. a. the latter means that the polluted atmosphere keeps warmth better, which makes the average temperature on the planet higher. b. this chain of changes will affect our life dramatically. c. people should do more to protect the environment. d. however, few people ever think about how dangerous our travelling is for animals and nature.
