It's almost a universal convention in european languages due to the influence of germany to use the capital letter this way. Eastern europeans explicitly use a definite article, "the nature", eg "Природата" (bulgarian) or "Природа" (rest of E. Europe) where germans write "Natur" and don't say Der/Die/Das.
Makes sense. I was just wondering if Satoshi was the one who suggested this convention. Some casual googling suggests it was someone else, and he never addressed this question. https://bitcoin.meta.stackexchange.com/a/22
