5.6 Threats to aquatic biodiversity and ecosystem services
Biodiversity
We have explored less than 5% of the Earth's ocean. Meaning that there are still many species to be discovered near the deep ocean floor
Services by oceans
Climate Control
Oxygen
Coastal Protection
Jobs
Food
HIPPCO
Excessive use of fertilizers casing euthrophication. exceswsive use of microplastics killing animals that eat it thinking it is plankton
See levels rise. Warmer oceans. Coral bleaching
Introduction of non native species for commercial use or accidentally
Coastal habitats are disappearing at rates 2 to 10 times higher than they should be. Dams alter water flow and destroys some aquatic habitats.
Fresh water damage
pollutant and fertilizers
Dams and Canals
Draing or filling wetlands. Happens due to mining or expanding residential areas
Flood control levees and dikes bult along rivers
Marine Damage
Seagrass beds- coastal development
mangrove- destroyed for firewoood
Coral reefs- dying due to warming up ocena water and human activity
sea bottoms- trawlers
Unsustainable fishing. Uses many techniques that have devastiating effects on the enviroment and on the animals of aquatic ecosystems
