A new study has revealed that the global economic recession could proliferate the spread of invasive species. The term ‘invasive species’ refers to foreign species that adversely affect the habitats they invade, particularly arising from international ships that carry barnacles and sea creatures into domestic water bodies.
According to Oliver Floerl of New Zealand’s National Institute of Water and Atmospheric Research, a large ship could have up to 80 tons of ‘biofouling’ accumulated on its hull. Since biofouling can costs thousands in reduced fuel efficiency—not good in this economy—operators want to clean up the mess as quickly as they can, which stands to potentially “dump a mess of foreign species onto the sea floor,” says Discovery News.
