Growing Fish And The Ecosystem
The need to be economical and be able to compete with rising economic giants in Asia, Latin America and elsewhere has led in a natural way to search for alternative energy source to heat greenhouses for crofts and fish.
The fisheries in Alabama pacing the need to be able to grow tilapia for more months then the five months that the weather allow have to start thinking on growing the fish indoor and this takes a lot of heating, which means electricity that is both expensive and bad for the environment.
Searching for a better way has led Dr Chappel to experiment with corn power that can be used for heating is much better for the environment and is much cheaper then the use of standard energy source.
This concern prompted Chappell and other Auburn researchers to consider other alternative sources of energy that, at least potentially, were substantially cheaper than more conventional sources — the electric power grid and LP gas.
They settled on corn power — one in which a burner for heating the house is run off corn kernels.
Chappell says this approach offers growers several distinct advantages. In addition to being a renewable energy source, it’s also versatile.
Right now, Chappell is spending more than $4 per bushel for the corn to run the burners that are heating the two demonstration greenhouses on the Auburn University campus. But that’s only because he doesn’t have the wherewithal to grow the corn on his own. On the other hand, many farmers do — and that’s the beauty of using corn as the alternative energy source.
If the economic consideration and the ecological consideration coincide we might witness the entrance of alternative energy sources to all realms of agriculture on a wider scale.
What can be more natural than to use the local energy source that the field has plenty of to sustain itself, it is simple, environmentally friendly, and cheap.
The other side of the story is explained in the post fish story. Our taste in fish is changing as a result of growing percentage of farmed fish. More and more farmers grow Salmon and Tuna at the expense of the ecosystem. These fish are fed of other fish and the whole process of supplying the demand for them is very harmful to the entire marine food chain. If you are asking what you can do today for the planet one of the answer can be found in using the guide that this site offers for eating fish that are good for you and good for the ocean.
