Carbon footprint
我们的日常生活制造了多少二氧化碳?
JUST about everything you do has an environmental impact(影响) on our planet, even small things such as putting on a light or washing a lot of clothes. Your “carbon footprint” is the amount of “greenhouse gases” produced, either directly or indirectly, to support your lifestyle.
For example, when you travel in a taxi, the engine(发动机) burns fuel and releases a certain amount of carbon dioxide into the air.
Carbon dioxide is greenhouse gas related to global warming. When you eat a cheeseburger , you’re indirectly contributing to the production of CO2(二氧化碳) . This is because cooking, transporting and storing that burger all require energy.
How big is your carbon footprint? To get a general idea , take a look at the following numbers.

你所做的一切事情都对我们的星球有环境影响，即使是像开灯或者洗一大堆衣服这样的小事情也会有影响。支持你的生活方式的“碳足迹”就引起一定量的温室气体直接或间接产生。

例如，当你坐出租车旅行，发动机消耗燃料并在空气中释放一定数量的二氧化碳。
二氧化碳是引起全球变暖的一种温室气体。当你食用干酪汉堡包，你就是在间接引起二氧化碳的产生。这是因为做饭，运输和储存这样的汉堡包都需要能量。
