An envirnonmentalist is someone who thinks they're caring for the environment but in fact just comes over as mental and causes more problems and greater energy expenditure.
People who evoke such stupidness are mental!
Let's have an earth hour at a non earth hour time... so as we can all sit in the office in the dark and strain our eyes. Everyone will think we're great and doing something good.
Everyone else in the office in fact thinks they're crazy and doing more harm than good in turning on and off lights that were performing optimally... therefore everyone in the office feels that they are Envirnonmentalists.
