Habitat Destruction
Many fishing and diving areas across the whole of South East Asia, already severely damaged from the impact of dynamite fishing, have been ruined or totally lost through cyanide fishing. Cyanide concentration slows photosynthesis in zooxanthellae, which results in coral reefs losing colour; it also eliminates one of their major food sources. Even at very low doses, cyanide results in higher mortality levels among corals.
Most legal and illegal fishing methods cannot by themselves destroy a stable ecosystem. However, through the effects of synergy, they have led to the breakdown of large coastal areas which were formerly robust fishing grounds.

Famous quotes containing the words habitat and/or destruction:
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
“Despotism may govern without faith, but liberty cannot.... How is it possible that society should escape destruction if the moral tie is not strengthened in proportion as the political tie is relaxed? And what can be done with a people who are their own masters if they are not submissive to the Deity?”
—Alexis de Tocqueville (1805–1859)
