Hawaii state officials say they expect thousands of fish to die after 1,400 tons (233,000 gallons) of molasses oozed from a leaking pipe into a Honolulu harbor.
A report from CNN says that while molasses itself is not toxic, the high concentration in the water is making it tough for fish to breathe. So far, several local television crews have already filmed dead fish on the surface and captured underwater footage of the sugary substance settling on the ocean floor, with dead fish, crabs and eels strewn about.
It could take weeks for tides and currents to dilute the molasses and carry it out to sea. Until then the Hawaii Department of Health is warning people to stay out of the vicinity in case the fish kill attracts predators like barracudas and sharks.
