The Young Green Consumer Guide says that our world is in danger. We must do something to save Earth. There are many environmental problems. What are they?
《绿色环保指南》这本书述说我们的地球正处于危险之中。我们必须想方设法拯救我们的地球。有许多环境问题等待我们解决，那么它们是什么呢？
The greenhouse effect
The writers ask us to imagine Earth inside a kind of greenhouse. The atmosphere around Earth acts like the glass. It lets sunlight in and keeps much of the warmth from getting out. It is important to us all. 'Without it, Earth would be as cold and lifeless as the surface of the moon .'
'The trouble is that our atmosphere is changing because we are polluting it with chemicals -- in the form of gases -- and it is keeping in too muchheat!' This will cause the level of seas to rise and drown cities and even countries.
第一：温室效应
作者要求我们想象一下我们的地球就好比一个温室。围绕我们的大气层就好比温室的玻璃。它让阳光射进来并不让温度散发出去。这个对我们来说很关键。没有大气层，地球就会像月球那样寒冷而不适合生存。而问题在于因为我们的气体化学污染导致我们的大气层不断变化，致使过多的热量被保存下来。这将会引起全球温度上升而使海平面上升最终淹没沿海城市甚至国家。
Destruction of rainforests
The burning and cutting down of trees is making the greengouse effect worse because tree take in harmful gases. It will also cause floods because trees can help hold soil together,and soil absorbs water when it rains .
第二：热带雨林的毁害
燃烧和砍伐树木导致温室效应更加加剧，那是因为树木能吸收有害气体。此举同时会导致洪流，这是因为树木能固定泥土，而泥土能锁住下雨渗透的水分。
Bad habits
Many of our habits cause pollution, especially our habit of using things once and then throwing them away. this creates mountains of rubbish and it pollutes our land and seas. For example, people throw away as many as ten nillion bottles in the UK every year. That is enough to reach all the way from Earth to the moon.
第三：一些坏习惯
我们许多的坏习惯会污染环境，尤其是使用一次性用品并用完随手乱扔。这导致了数以亿计的垃圾污染我们的土地和海洋。例如在英国，每年人们丢弃的废瓶数量高达1000万个，（楼主打错了是million吧？）叠起来足以覆盖从地球到月球的距离。
How can we save earth?
In prder to save Earth, the book is aksing us to become 'green consumers'. That is, we should only buy and use 'environmentally friendly' things. These things will not damage the environment.
第四，我们如何拯救地球？
为了拯救地球，这本书要求我们成为绿色消费者。也就是说我们应该购买并使用绿色环保的东西。这些物品不至于损害我们的周边环境。
