Or, get a frame pump. Then you dont need co2. Problem solved.
So where does the CO2 in CO2 cartridges come from? Assuming that it comes from the air, we haven't added or subtracted anything by using it in our bike tires.
Planting trees is only a temporary solution. Eventually the trees will die and decompose, then all of the CO2 they hve absorbed during their lifespan will be reabsorbed into the atmosphere. It's kind of like storing it in a bike tire.
