If biochar is such a good thing, why aren't everybody doing it?

That question was posed today at the coffee table. A very non-scientific question perhaps but I think it contains a few points.
1. We (in the west) are too distanced to energy production and consumtion to realize the amount of resources it demands. As long as the light goes on at the turn of a switch and the water is hot in the shower nobody really cares.
2. We have no or very little connection to the food we consume. Some state that we would eat far less meat if we somehow could see the cow behind the beef. All this leads to less interest in conserving farmlands and protecting forests.
