Some governments even collude in overfishing.
In addition, incorporating the effects of environmental variation [82], multiple human stressors [83], and linkages in interaction webs [84], [85] with socioeconomic factors that lead to overfishing [86] may improve management and conservation in coral reef systems.
But by far the biggest factor is overfishing, especially by large and often heavily subsidized industrial fleets.
Part of the problem has its roots in past overfishing.
Other factors are also in play, with overfishing killing off the lobster's natural predators and herring bait used in lobster traps being stolen by younger members of the species too small to be caught.
A few minutes later, Mr. Broderick pointed out that press coverage, according to a British study, was a key factor in the effectiveness of "The End of the Line," a documentary about overfishing.
However, anthropogenic factors such as pollution, overfishing and fertiliser run-off pose a more immediate threat to coral.
Thus, the combined factors of susceptibility to overfishing, low annual productivity, and their association with the nearshore zone make for a low resilience for local area populations of copper rockfish and lingcod in the event of a major disturbance.
The impacts of climate change, eutrophication, and other secondary factors (e.g., changes in species composition, overfishing) on the net transfer of atmospheric Hg deposition into the aquatic food chain as CH3Hg are often ignored in model projections of future changes in the global Hg cycle.
There is historical evidence of overfishing in some parts of the Western Mediterranean in the early Imperial period [253].
