Notice to skippers
There is plenty in all of this to understand that the sea of sustainability, in addition to being very insidious, cannot continue to be shaken (only) by the extremism of a “no”. To persevere in highlighting the un-sustainability of others (true or presumed), it's just smoke in the eyes. It would be better to enter a new dimension, recognising the concreteness of certain continuous improvement programs (those of Italian leather, for example) and seriously roll up their sleeves.
