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: В мене була також інша ідея, яку мені підказав еколог — він просто зробив розрахунок, в якому він узяв один літр газу і сказав, отже, скільки треба вуглецю, і скільки органіки?
