As for the problem of the environmental load
of the carbon dioxide, it is argued all over the world. But
reactive nitrogen load has the same problem to the environment
that we cannot ignore.
The consumption of the reactive nitrogen increases in form
of the fertilizer, by the expansion of the cultivation area and
with the increase in population adds more problems for us to
face.
As for the surplus reactive nitrogen, possibility to have various
influences on environment is pointed out. The reactive
nitrogen may decrease biodiversity by eutrophication of the
soil, river water, and seawater. The atmospheric reactive
nitrogen causes the acid rain which flows into the ocean and
produces dead zone.
By the way, Sea-plant grows without fertilizer and it takes
underwater reactive nitrogen. We may conclude that Seaplant
is thought of as “Nitrogen-neutral”
Therefore we are proposing the theory called the recycling
society, environment load can reduce by the use of the Seaplant
in various forms that cultivation seems to be possible
even if we do not use new reactive nitrogen.
