The problem is that if you are advocating that asbestos be banned, you must know that this fibre has been studied over and over again by the Government of Canada. We know that, according to the scientific community, when asbestos is used in a safe manner, it poses no danger. On the other hand, we are not sure what the case is with replacement fibres.
If asbestos were to be banned, what should we do about these replacement fibres when we don't know anything about the dangers they may pose for human health? Are we not placing ourselves in a precarious position?
