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?
Ide lainnya yang saya pikirkan adalah, berawal dari seorang ekologist (ahli lingkungan) -- yang melakukan penghitungan mendasar dari satu liter minyak dan berkata, berapa banyak polusi karbon yang dihasilkan, dan berapa banyak bahan organik?
