Deep-Sea Mining: a Manageable Necessity or a Curse?

The dependence of modern societies upon critical raw materials (nearly all metals) is overwhelming. Some believe that demand is growing faster than offer, not only because of geological availability but also for political and economic reasons. For these reasons it is imperative to consider new sources for raw materials.The seafloor stands as a likely candidate. We must create readiness now to be prepared when the need comes. One of the greatest fears is the environmental cost involved in mining the deep seafloor. However, the mining industry no longer deserves its partially not favorable reputation. We need both the resources and the environment. And nIMBY (not In My Back Yard) will not help.
