In this work we have shown that the strength or range of the strong force is fine tuned to ±0.5 % by the production of carbon or oxygen and therefore also carbon-based life. This leads to a fine tuning of the sum of the light quark masses as well as the Higgs vacuum expectation value and mass parameter to about ±1 %. One of the most fascinating aspects resulting from this is that life, stars, nuclei and elementary particles seem to be closely interwoven in our universe through this extreme fine tuning. It is not clear if the values of the fundamental parameters corresponding to this anthropic fine tuning will be calculable by a future Final Theory [39] or if some of the parameters of such a Final Theory will have to be chosen from a large or continuous ensemble [36]. In any case it will be one of the challenges for a possible Final Theory to explain the anthropic fine tuning as described in this paper.
