    ----------------------------------------------------------------------------------------------- Transcript: What is Eutrophication? It’s a problem that should matter to you, whether you live near the ocean or not. That’s because it begins wherever people live and ends with damage to resources we all use and enjoy.It all starts when nutrients get into lakes and oceans. Remember, what’s waste to humans can be food to plants and other creatures. Nutrients feed algae, like they do other plants. Algae grows and blocks sunlight. Plants die without sunlight. Eventually, the algae dies too. Bacteria digest the dead plants, using up remaining oxygen, and giving off carbon dioxide. If they can’t swim away, fish and other wildlife become unhealthy, or die without oxygen. But it doesn’t have to be this way. Protecting marine resources starts with sound agricultural and waste management practices. Show less

    Ocean Today is an interactive exhibit that plays short videos on ocean related themes. Visitors can select from 200+ videos on topics ranging from deep-­‐sea exploration, marine species, and restoration projects to hurricanes, oceans and human health, and climate science and research. These videos are a free resource and are available on our website at oceantoday.noaa.gov.

    The Ocean Today kiosk was originally developed for the Sant Ocean Hall -- a permanent exhibit at the Smithsonian Institution's National Museum of Natural History. Ocean Today kiosks are now located at 37 aquaria, science centers, museums, and visitor centers in the U.S., Canada, Mexico, and the U.K. To learn more about the program or to get a kiosk at your facility, visit our website.
