Aquatic Food Production (ESS 4.3.1 - .4.3.3)

* Unsustainable use of aquatic ecosystems can lead to environmental degradation and collapse of wild fisheries.
*Aquaculture provides potential for increased food production.
***note: I moved too quickly through the part about Freshwater Ecosystem and the 'zones' found in these areas.
