5.6 threats to aquatic biodiversity and ecosystem services
ocean ecosystem and economic services
services preformed by the ocean
food
around 40% of the human population get 15-20% of all animal protein from the ocean
essential nutrients are gained from eating seafood
jobs
the ocean creates around 850 million jobs
mostly fishing and tourism
oxygen
the ocean generates more than half the oxygen we breath
costal protection
they are natural barries
mangroves
coral reefs
seagrass beds
protect against tsunamis
climate control
oceans absorbs 25% of all CO2 released
oceans help slow down atmospheric warming
biodiversity in the ocean
biodiversity is greater in coasts that in open seas
example, coral reefs are very biodiverse ecosystems
this happens because of a larger variety of producers and habitats in costal areas
