This synergy has enabled a directed and sustained exploitation of A. gossypii as an industrial riboflavin producer.
Only a few occur in quantities large enough for sustained exploitation, notably iron in Pennsylvania's Blue Ridge and Piedmont and the famous granites, marbles, and slates of northern New England.
This is a scientific area in permanent development, where the knowledge of fisheries biology is applied in order to make a rational and sustained exploitation of the fishing resources.
It is possible that the multispecies tropical nature of these fisheries can sustain such exploitation patterns, although if one traces the history of development of fishing in heavily fished countries such as China, one question is how long this can continue.
Populations of a number of wild animal species in protected areas in these countries could sustain some exploitation.
Furthermore, from a strategic point of view, PCDC represents a potentially attractive routeto sustaining economic exploitation of fossil fuels and is a first step on the evolving pathway to an energy economy based on hydrogen.
Perhaps most seriously of all, however, is the fact that the kind of sensationalist reporting that underlies and accompanies league tables around slavery or trafficking distracts attention from more important discussions over the global economic forces that create and sustain poverty and exploitation.
How much finger pointing is possible with so much tyranny, injustice, and greed accompanying the postimperial integration of the planet, and its frantic exploitation to sustain at least seventeen times as many people as inhabited it in 1415?
All three thresher shark species were assessed as Vulnerable by the IUCN in 2007, as their low fecundity cannot sustain high levels of exploitation.
Such impacts are particularly acute in fisheries of deepwater demersal species, both because of the use of non-selective gears that potentially impact fragile habitats, and because they often target marine species with low productivity which cannot sustain high rates of exploitation.
In the late 20th and early 21st centuries, the only mineral resources of West Bengal that sustained nationally significant exploitation were coal and clay for brickmaking.
