章节摘录

版权页：插图： A greenhouse is a building made of glass which is used for keeping plants warm when theoutside temperature is how. In a similar way there are several gases in the atmosphere whichtrap（捕捉） the heat produced by the sun and prevent it from escaping. These gases are knownas" greenhouse gases", and the way in which they trap heat in the atmosphere is called the"greenhouse effect". This is not simply air pollution. Most of the main greenhouse gases existnaturally in small amounts in our atmosphere. And without them earth would be 30 degrees col-der and human life would not exist. In other words, the greenhouse effect is a natural coursewhich is to some degree helpful to us.  The problem is that in the last century, and a half, we have been putting too many of thesegases into the earth's atmosphere by burning large quantities of coal and oil and by cutting downforests. The rapid increase in greenhouse gases is making the world warmer. The world's temper-ature has already gone up by half a degree this century, and the sea level has risen by 10 centi-metres. If the amount of carbon dioxide （二氧化碳）in the atmosphere doubles, there will proba-bly be a rise in the earth's temperature of between 1 and 4 degrees. This may seem a small in-crease, but it would be enough to cause major changes in geography and agriculture. Large areasof the world would be flooded, and some areas would become dry and unable to produce crops.It is important , too , to consider that there may be a delay of about 30 years in the greenhouseeffect. This means that we're probably experiencing only now the effect of the gases put into theatmosphere before the 1960s. Since then,our use of these gases has greatly increased.
