*Waterways receiving nitrogen from human activities are significant source*

What goes in must come out, a truism that now may be applied to global river networks.

Human-caused nitrogen loading to river networks is a potentially important source of nitrous oxide emission to the atmosphere. Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. (more…)

The successive and increasingly frequent occurrences of environmental disasters caused by human activities deserves our utmost attention. Leading us to necessarily suspect that we should have credible and foolproof trials before accepting assertions regarding existing technologies.

The most striking example is the disaster caused by the explosion and sinking of the Deepwater Horizon oil exploration platform by British Petroleum (BP) which happened last April 20, and which day after day has reached catastrophic proportions.
