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?
و یک ایده‌ی دیگری که من داشتم هم این بود، که از طرف یک بوم شناس مطرح شده است -- او ابتدایا یک محاسبه ای انجام داد جایی که او یک لیتر بنزین آورد و گفت، خوب، این چقدر کربن دارد و چقدر مواد عالی دارد؟
