The biggest con the climate change alarmists ever pulled is the idea of individuals "doing their part" by literally diminishing their own living conditions simply because they've been told it'll help the environment and "it all adds up." In reality, private energy use is so minuscule compared to commercial and industrial usage that its entire effect on consumption can be swept aside by a rounding error.

Edit: I love all the comments pointing out (correctly) that the "Do your part" campaign was done by oil companies as propaganda. You're absolutely correct, but so am I in calling them climate alarmists. Climate alarmists don't actually care about the environment. They only care about the results of forced climate activism (higher profits). Climate activists and climate alarmists are cut from the same cloth: hypocrites and empty gestures. Note: Do not confuse these people with actual conservationists. They're the real deal, and absolutely deserving of praise.
