HA! Ask artificial intelligence to help understand cycling's sustainability issues and like me, you might be surprised when informed, e.g.

• Resource consumption for cyclists: A 2020 BikeRadar article notes that about three-quarters of cycling's greenhouse gas emissions are from producing the extra food required to "fuel" the cyclist, while the rest comes from manufacturing the bicycle. This means a cyclist's overall carbon footprint depends on the sustainability of their diet.

Cheers!
