organic contamination. Instead, the decomposition processes caused
by the aerobic bacteria produce toxins, such as hydrogen sulphide,
ammonia or methane, and the stretch of water becomes polluted and
“dies”. This in turn leads to the dying of fish. According to reports
by the U.S. National Oceanographic and Atmospheric Administration
(NOAA), eutrophication of this nature has caused mass mortality of
marine animals in the Gulf of Mexico. Satellite pictures have revealed
a similar phenomenon of colossal dimensions in the northern region
of the Caspian Sea, to the east of the Volga Estuary. These zones are
then referred to as “dead zones” because hardly any marine creatures
can survive there.

There is nothing to be said against using reasonable amounts of
fertiliser which plants would be well able to absorb. Problematic,
however, is intensive agribusiness where farmers have their eye on
profits and no longer pay any attention to collateral damage, their sole
intention being to harvest the largest possible yields in the shortest
possible time. Everywhere, the soil is being exhausted as a result
and then subsequently contaminated by over-fertilisation, as are our
ground water, lakes and rivers.
