The six-year long permitting of the Huntington Beach (Calif.) Poseidon desalination plant is being completed. It is time to review the arguments voiced against this iniciative. The most imbecile, I daresay, is that the capitalist financing the plant will be profiting from seawater, which is public property.
Federal and state laws, including the California Coastal Act, treat ocean water as a part of the public commons that must be used primarily for non consumptive uses. One purpose “does not necessarily impair its ability to be used for others,” according to a 2004 analysis by the California Coastal Commission’s research staff. In contrast, privatization advocates treat water as a commodity and more of a human need rather than a human right.
I can assure the persons who fear that Poseidon may be consuming too much sea water, a common property of all humanity, that their fear is without foundation. All the seawater consumed will eventually find their way back to the sea or the atmosphere. Poseidon will not dry up the oceans, and enough sea water will be available for any other use the Californian environmentalists may be entertaining in their minds.

The second stupidest argument is that Poseidon will cause the disminution of fish (see illustration) in the sea. The argument is absurd not only quantitatively, because humanity extracts from the oceans hundred xillions cubic meters of fish per year, with international treaties tightly regulating this industry. Of course Poseidon will do everything to exclude and filter out the fish from the water it needs. Anyway, Poseidon people thought it below their dignity to debate such stupid argument, and agreed to create an artificial wetland where the fish (see illustration once more) theoretically displaced could call home.
The qualitative argument is the one I never understood. Say that before the building and operating of the Poseidon plant, there were two xillion small fishes we call the
schmietzsch. Say the
schmietzsch likes sea water with 30,000 mg salt/lt and the plant will increase salinity in a 100 meter radius of its marine outfall. Some
schmietzschen may have to emigrate. The overall number of
schmietzschen may decrease to only one trillion and nine hundred billion, but a second species called "the
saltwater schmietzsch" that looks exactly like the
schmietzsch will colonize the newly underpopulated waters. The overall biomass will not suffer or even increase. Diversity will increase. By what law of nature there is a need for a fixed number of
schmietzschen to exist? Every living population fluctuates, there are no fixed numbers at all. And the
schmietzsch may even be a Central European immigrant species that arrived to California in 1946. What are its rights? Why Poseidon has to build an artificial
schmietzsch paradise? All ecosystems are temporary and changing all the time, why should the one perturbed by desalination be considered eternal, holy, to be maintained forever? Forever? How long we have to be breeding and feeding
schmietzschkes - 50 years, 100 years, or 1,000 years will be enough and then, what? The
schmietzsch will never die out?
And if it does, what?
