My hunch is the fish are not to happy about it either.
Fishermen have often joked, after hours of not catching anything, that they wished they had some dynamite. But in the Mentawai Islands in Indonesia, fishing with explosives is no joke: This practice, carried out illegally by visiting fishermen aboard skiffs, is destroying precious reefs that are critical to the health of the marine ecosystem. The reefs also are important for a tourism industry supported largely by surfers, who visit because of the perfect waves that break over the reefs, but also because of the pristine nature of the region.

A petition has been established and those who care about the people of the Mentawais and the marine environment are encouraged to sign.
