Besides that, what other options are there to produce light nowadays besides electricity? You're certainly not going to use candles for a bike light. That would result in higher overall emissions anyway.By that logic nothing is zero emission, what did it take to make a bicycle, the steel, the rubber, the paint, the grease lube......
The only way to be zero emissions is to walk naked, cuz making clothes involves emissions too.
Fact is every human being, really every animal, has an impact on the planet. Thankfully, nature has balance. Humans breathe in oxygen, breathe out CO2. Plants do the opposite. Plenty of organisms eat the waste generated by other animals.
Now if only human civilization could function like that. A lot of the waste we generate isn't usable by any life form. Some of it is toxic besides.
