As if the number of probable problems for mankind in the near future (carbon, global warming, fresh water, energy/oil) weren't enough, up pops another scientist with a new problem: build up of Nitrogen... I guess the real problem is we are with too many. But how to regulate that? The Chinese one-child-policy? Although what China did/does might not be necessary / the only solution.

A nice video on the threat of the growing human population from David Attenborough:
Another great video you should watch is Home, a movie by Yann Arthus-Bertrand showing how beautifull our planet is, and how we are 'using' it.
