“We’re running up to and beyond the biophysical boundaries
that enable human civilization as we know it to exist,” says Professor Stephen
Carpenter, director of the Center for Limnology at the University of Wisconsin,
Madison. “Everything important to civilisation,” Carpenter contends, took place
prior to 1914. “The development of agriculture, the rise and fall of the Roman
Empire and the Industrial Revolution” were some of the best thing that happened
to our world – until about 100 years ago when the activities of man began to
destroy the earth.
Carpenter and his team of researchers examined the problems
and impact of carbon-driven global warming and how it affects sea level rise
and biodiversity loss among others; and they came up with a discovery that
“We’ve changed nitrogen and phosphorus cycles vastly more than any other
element. [The increase] is on the order of 200 to 300 percent. In contrast,
carbon has only been increased 10 to 20 percent and look at all the uproar that
has caused in the climate.” The researchers stated that the use of artificial
phosphorus and nitrogen to boost agriculture in the US is unnecessary because
the land is already blessed with rich nutrients beneficial for bumper harvests.
Since phosphorus and nitrogen do not have even distribution
in the soil, it is richer in the United States than in places like Africa,
hence the problem Africans face with growing food without artificial
fertilizers. “We’ve got certain parts of the world that are overpolluted with
nitrogen and phosphorus, and others where people don’t even have enough to grow
the food they need,” he says. He advised industrial farmers to cut down on the
wanton use of phosphorus and nitrogen because it is upsetting the ecosystem.
