Peru’s guano supply threatened by overfishing 3

Peru is in deep shit. No, seriously: thanks to an exceptionally dry climate, islands off the Peruvian coast are awash in preserved bird guano, which the country has long exported as non-chemical fertilizer. But while 60 million seabirds were pooping on Peru in the 19th century, the birds now number 4 million; with synthetic-fertilizer costs and interest in organic food rising, the Peruvian government is concerned that guano supply will be depleted by high demand. Guano collection has been restricted to two islands per year, lizards have been introduced to eat seabird-bothering ticks, and armed guards have been posted to ward off threats to birds. But guano preservationists despair of keeping commercial fisherfolk from depleting the anchoveta, a fish that's both the seabirds' favorite food and in high demand for factory-farm-bound fishmeal. Without fishing restrictions, biologists estimate that the anchoveta, the seabirds, and the guano could be gone by 2030.

    At one point......nearly all of the world's fertilizer came from these islands.  Reports of guano more than 150 feet deep were common.
    Now, there's hardly any left.

    Meanwhile,fertilizer made directly from fish, without having to go through a bird's alimentary canal, is highly recommended, even by promoters of organic gardening:

    Talk about unsustainable!

    Ugh...In light of revolutionary new farming techniques which don't seem to require fertilizer of any type to be shipped to your farm, it astounds me that we are proving so slow to catch on. I mean, I know that composting is a very new technology and no has really had a chance to get it going, but I still think we could give it a chance.
