Abandoned ships damage the ecosystem(生态系统)long after they‘ve sunk. They produce toxic chemicals harming or destroying sea life and, by entering the food chain, the chemicals are finally digested by humans. Sometimes they help the growth of new sea life that threatens the present local ecosystem. On Palmyra Atoll, for example, a ‘population explosion’ of corallimorph, an aggressive creature similar to coral, killed almost all the coral growing around a fishing boat that sank in 1991. The corallimorph were probably attracted to the leaching iron produced by the abandoned boat, growing fast and threatening other sea life on the reef.
Of course, there are governmental policies to prevent people from abandoning boats and ships. State laws fine (罚款) and sometimes jail those irresponsible ship owners. However, there’s a big financial problem regarding retrieving(回收)and recycling sunken ship: it takes owners on average $5,000 to $10,000 to retrieve a 40-foot yacht, while the fines for abandonment are much lower - only $100. Besides, definitions of ‘abandonment’ are quite different among states, which means that ship owners can sometimes sink boats and get off the responsibility. Meanwhile, federal law deals with only pollution caused by ships, not with ship abandonment itself.
The environmental impact of undersea boats and ships can’t always be seen easily from the shore, says Helton. It would help if owners of small fishing boats as well as big ships could keep in mind that ‘ when a boat or ship is lost, it’s not gone.
