Hawaii's economy relies on their coral reefs for an estimate $10 million tourism business. Freshwater invasive species also threaten Hawaii's ecosystems. In 2003 Lake Wilson was invaded with the floating water fern Salvinia. The invasive fern competed with native species and fish. It has cost the state over $1 million to clean up the lake. [9]

[ 12 ] Hawaiian monk seals can hold their breath for up to 20 minutes and dive more than 550 m (1,800 ft); however, they usually dive an average of 6 minutes to depths of ...
Hunting and introduced predators, such as small Indian mongooses, pigs, and feral cats, reduced the population to 30 birds by 1952.

This group of birds historically consisted of at least 51 species. Less than half of Hawaii's previously extant species of honeycreeper still exist. [1] Threats to species include habitat loss, avian malaria, predation by non-native mammals, and competition from non-native birds. [2]
