我们每天出行、吃饭、洗澡等行为都会产生二氧化碳的排放，这也就是我们的“碳足迹”。如今环保观念虽然慢慢开始深入人心，不过生活中还是有些人没什么环保意识，浪费资源的行为看着都让人心痛。

Carbon Bigfoot refers to a person with absolutely zero regard for his or her carbon footprint, the sum of all emissions of CO2 induced by your activities; an anti-environmentalist.

Carbon Bigfoot（碳大脚）指完全不在意自己碳足迹的人或者反环保人士。碳足迹指一个人的行为产生的二氧化碳排放量。

For example:

The elusive office Carbon Bigfoot appears to be Gary. The other day I watched him wad up 600 sheets of computer paper in pursuit of the perfect wastebasket three-point shot.

办公室里隐藏的“碳大脚”原来是Gary。有一天，我眼看着他把600张电脑打印纸揉成纸团对着垃圾筐练三分投篮。
