english: And another idea that I had as well, that was brought forward by an ecologist -- he basically did a calculation where he took one liter of gas and said, well, how much carbon it would take, and how much organic material?
non_english: Još jedna ideja koju sam imao, a koju je predložio jedan ekolog - u principu on je uzimajući u obzir litru benzina proračunao i rekao: "Koliko je potrebno ugljenika i organskih jedinjenja?"
