我們每天出行、吃飯、洗澡等行為都會產生二氧化碳的排放，這也就是我們的“碳足跡”。如今環保觀念雖然慢慢開始深入人心，不過生活中還是有些人沒什么環保意識，浪費資源的行為看著都讓人心痛。

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（碳大腳）指完全不在意自己碳足跡的人或者反環保人士。碳足跡指一個人的行為產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.

辦公室里隱藏的“碳大腳”原來是Gary。有一天，我眼看著他把600張電腦打印紙揉成紙團對著垃圾筐練三分投籃。
