What is a carbon frame?

Carbon fiber is a byproduct of petroleum and the more we use it the more oil we consume as a society. I suggest we do not use plastics in our buildings as they are highly toxic to our health. Stick with wood and stone. Metals conduct electricity and are bad for our mental health as they conduct too much energy and it bounces through the building. We need a calm environment to be healthy, and wood and stone are the most calming.
