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: Ďalší nápad, ktorý som mal, mi predložil jeden ekológ. Robil výpočty, v ktorých zobral jeden liter ropy a opýtal sa, aké množstvo uhlíka a organického materiálu by na to bolo potrebné?
