Justifying using a pump (I am going to guess I have given away 50 canisters to the pump crowd, and a like number of tubes to folks who have ripped the valve off the tube on the one tube they brought) for environmental reasons is hilarious. You still have to deal with your tube.

It's hilarious watching people trying to get the last 30 pounds of pressure into a tube so they don't enjoy a pinch flat. Especially when it's 100 degrees outside.

CO2 is convenient and fast.
