Of course they don't. If they did they would start to ask questions about how many litres of red diesel is required to make one litre of biodiesel.I don’t think non-farming people realise quite how much diesel is sucked up to prepare ground for cereal crops or, as above, recognise the point above ^^^ that not all land can be ploughed up. Animals also use the waste straw and provide excellent natural fertiliser. Mixed farming is the way, and has been for millennia.
Corn is turned into ethanol here and the left over distillers grains are fed to cows, and probably pigs. Soy was introduced as a protein source for animals, but is probably well used for both humans and animals at this point (expensive compared to corn).The devil's crops: maize (to make high fructose corn syrup) and soya (for animal feed)
Same as wind turbines, box ticking. Over 1 tonne of co2 to produce 1 tonne of steel. How many tonnes in the tower of a wind turbine? All BS. Only half the narrative that should be spoken.
