Ok, so maybe the title of the post is a bit misleading. Or is it?
After seeing this child, I had to point out the following.
When you ride a bicycle, you generate heat. Your body warms up as you burn calories. You vent most of it out through your head as every Canadian child is taught as a youngster. (wear your hat and all that).
So why do environmentalistas not complain about the heat being generated by bicycle riders? Or worse. Why are they not protesting outside the Olympic games?? How about at triathlons? Do you know how much the water is warmed with all those swimmers? Do they not know how much that can melt our polar ice caps?? For shame.
Ok, so my tongue is in my cheek. But one day soon, I will get enough energy up to burn on presenting some laws of conservation of energy and laws of thermodynamics.

You forgot to mention Co2, when you ride a bike you breath harder expelling more Co2. It’s the human equivalant of an SUV. We must all remember that it is vitally important that we breath as little as possible, preferably not at all. Because it is Co2 (otherwise known as plant food)that will ultimately doom us all, just ask David Suzuki.
