例文：
As is subtly portrayed in the cartoon, two tourists are taking sightseeing on a small boat while discarding their picnicking leftovers casually into a lake. Unfortunately, the lake is already littered and teamed with flowing rubbish like plastic containers, fish-bones, banana skin, watermelon rind, bottles, tins, food wrappings, and so on. And below the drawing, there is a topic which says: "after" the travel 。
From the portrayal, we can conclude that the painter wants to convey such a message: a good many popular places are flooded with visitors, who spoil the beauty of nature by creating and leaving behind God-knows-how-much trash. On the one hand, tourism, as a multibillion-dollar business, is booming everywhere. Some people, laboring under the belief that tourism serves as an engine of economic growth, seem to ignore its negative effects on the environment.
Nevertheless, it is my view that these are not concerns that we can shrug off lightly. On the other hand, tourism has exerted great pressure on the environment we are living in: water is polluted, the ecological system is disturbed, and natural resources have been excessively used。
Undoubtedly, tourism could not be banned in any country as it does help to shore up the economy in places which offer few sources of income. The significant point is that the unchecked growth of the travel business may render the development of an economy unsustainable. It is high time that we enhanced people's awareness to rectify this by taking the environmental protection into consideration. (255 words)
