I guess some people just don't bother to research. My brother built a high budget system last year and when I recommended a 7800X3D, he was all "really? an AMD? doesn't Intel have something better?"
Some quick searching gave me around 100 tons of carbon for 1 ha of forest and around 5 m^3 of biofuel per year for the same area of arable land. I.e. one liter of biofuel initially releases 20 kg of carbon or around 60 kg of CO2. So biofuel starts to be better for the CO2 levels after about 20 years?
