Most of us are aware that1 we must take care of the environment, and the majority of us take steps to save energy and reduce waste and pollution2. But recently, some “green truths” have been shown to be only half true, or even completely false. Here are some common ones. Which are really green?

我们大部分人都意识到要保护环境，也采取了各种行动节约能源，减少浪费和污染。但是近来，一些“绿色环保真相”被证实并非完全正确，甚至是无稽之谈。下面列举了一些常见的环保观念，其中哪些是正确的呢？

Paper shopping bags are better than plastic ones.

纸质购物袋优于塑料袋？

Plastic bags cause litter and are a danger to wild animals, which3 mistake them for food. It takes hundreds of years for plastic to break down4，but much less time for paper. Because of this, people think paper bags are the better environmental choice.

  However, making a paper bag5 uses four times as much energy as making a plastic bag6 and up to three times the amount of water7. The process also produces more greenhouse gases.

  In fact, both kinds of bags are bad for the environment. So, take a reusable bag with you when8 you go shopping.

塑料袋会变成垃圾，被野生动物误食后会对其造成伤害。塑料需要数百年才能分解，而纸的降解时间要短得多，因此人们认为纸袋是更为环保的选择。

然而，生产纸袋的耗能为塑料袋的四倍，耗水则多达三倍。其生产过程也会产生更多的温室气体。

事实上这两种袋子都不够环保，所以出门购物时请带一个能重复利用的袋子。

When you turn off a device, it stops using power.

关掉的电器不耗电？

When9 we turn off a device, such as television, it goes into stand­by mode. Devices in this mode still use power, and older devices in stand­by mode can use even more. This happens because10 electricity continues to leak from the device, even when11 it is turned “off”. To make sure12 your appliance is in fact off, remove the plug from its power supply.

当我们关掉电视等电器时，它会进入待机状态。这种状态下的电器仍然耗电，而且越旧的电器耗电越多。这是因为电器即使已经被“关掉”了，却依然有电流从电器中流失。为确保电器设备彻底关闭，请从电源上拔下电器插头。

Eating local food is good for the environment.

吃本地食物更利于环保？

It seems like common sense: eating local food13 should be better for the environment, because14 it does not need to be transported long distances and kept cold during transport. Unfortunately, it is not that simple. It is the production of food, not its transport, that15 uses most of the energy and produces most of the greenhouse gases. In some cases，local produce might have used more energy and produced more
