Testing the waters
Testing the waters Michael Markels, a chemical engineer from
Virginia, USA, believes that he can encourage the population growth
of fish in the open oceans by adding nutrients such as phosphorus
and iron to the water. He hopes that larger numbers of fish
available in the oceans will help to feed the world. As well, a
benefit of concentrating on fish farming would be that burning of
fossil fuels used in agricultural farming would be reduced and this
would help global warming. However, oceanographers are saying that
all this sounds too good to be true. One of Markels' biggest
critics says his plan could trigger the world's worst-ever toxic
tide and risks making global warming worse, not better. At best, it
might marginally increase production, while destroying the entire
ecosystem. Even so, Markels has been using his own money plus funds
from investors, with the aim to commercialise the idea. 2 OCTOBER 1999, P. 34-37
