Kawainui is a big system made up of the plants, animals, sun, and the water. The sun is a very important part of this system. It is the starter of the whole thing. It shines on the pond and makes the algae grow which the little fish eat . The big fish which people and frigates eat eat little fish. The plants give oxygen to the animals and the animals breath out carbon dioxide.
The hyacinths are covering up the ponds. If this continues it will destroy the whole system. All of the animals and plants must work together to keep the system going.
