The problem with lists like that is that they make you feel better while really doing very, very little. Even if we could get 25% of the US and European population to do those things, it would have very little impact on the actual amount of CO2 being pumped into the air.
Of course, the original list, as everyone says, is just a ridiculous waste of time.
I wish there were a resource for what actually to do about climate change, instead of this crap. For example, getting politicians elected who takes climate change seriously will be many, many times more impactful than biking to work for a year.
With that in mind, I just started a thread to crown-source a real list: List of actually-meaningful things we can do about climate change
