It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself: it is a part of a system (体系) in which all forms of 
life are joined together. If we change one part of the natural order, this will in its turn almost certainly bring about changes in some other part.
The cutting down of forests reduces the supply of oxygen. The killing of weeds and insects by chemicals leads to the wide spread poisoning of animals and birds. The throwing of waste products into the ocean harm to life in the sea, while waste gases change the chemical balance of the atmosphere.
And so we could go on, adding more examples, until in despair (绝望) we might feel like giving up the struggle to control and keep within limits these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but not so clever at looking far ahead, or at thinking about what the future results of
his action might be.

The light from the campfire brightened the darkness, but it could not prevent the damp cold of Dennis’s Swamp (沼泽地) creeping into their bones. It was a strange place. Martin and Tom wished that they had not accepted Jack’s dare. They liked camping, but not near this swamp.
“So,” Martin asked as they sat watching the hot coals. “How did this place get its name?”
“Are you sure you want to hear it ? It’s a scary story,” warned Jack.
“Of course!” cried out Tom. “If there were anything to be scared of, you wouldn’t have chosen this place!”
“Ok, but don’t say I didn’t warn you,” said Jack, and he began this tale.
“Way back in time, a man called Dennis tried to start a farm here. He built that cottage over there to live in. In those days, the area looked quite different ---- it was covered with tall trees and the swamp was a crystal-clear river. After three hard years, Dennis had cleared several fields and planted crops. He was so proud of his success that he refused to listen to advice.
“‘You are clearing too much land,’ warned one old man. ‘ The land is a living thing. It will hit back at you if you abuse it. ’
“‘Silly fool,’ said Dennis to himself. ‘If I clear more land, I can grow more crops. I’ll become wealthier. He’s just jealous!’”
“Dennis continued to chop down trees. Small animals that relied on them for food and shelter were destroyed. He was so eager to expand his farm that he did not notice the river flowing slowly towards his door. He did not notice salt seeping to the surface of the land. He did not notice swamp plants choking all the native plants.”
“What happened?” Martin asked. It was growing colder. He trembled, twisting his body closer to the fire.
“The land hit back ---- just as the old man warned,” Jack shrugged. “Dennis disappeared. Old folks around here believe that swamp plants moved up from the river and dragged him underwater. His body was never found.”
“What a stupid story,” laughed Tom. “Plants can’t …” Before he had finished speaking, he screamed and fainted (晕倒). The other two boys jumped up with fright, staring at Tom. Suddenly, they burst out laughing. Some green swamp ivy (常春藤) had covered Tom’s face. It was a while before Tom could appreciate the joke.
