Masks are an example of the weaponization of the precautionary principle. “If it saves just one life, it is worth it”. “You can’t be too careful”. Neither of these is true. A correct application of the precautionary principle means considering not only the benefits, but also the negative impacts of an intervention.
… Oxygen is not the problem in most cases … CO2 – carbon dioxide – is actually the gas that we should be discussing.
… the mask is made up of small plastic fibres. Masks break down and these fibres are shed. Guess what happens when you breathe in with a mask on? These fibres may be benign when inhaled. But there is no reason to assume that.
