"Human activities have approximately doubled the amount of reactive nitrogen cycling though the biosphere compared to pre-industrial conditions, with most of this increase occurring during the last thirty years.3
The largest human additions of nitrogen stem from an increased use of inorganic fertilizers.4"
Why would I want to debate with a troll who hides behind an anonymous address?
You don't need my email address to respond to a newsgroup posting. That's why I don't post it here where harvester bots can find it.
In two years of postings, no one except you has ever mistaken me for a troll. You can find my postings by searching the archives for "replyonlist.com", "organic-earth.com" and, of course, "notarealserver.com" in the sender field of whatever search mechanism your newsreader / web browser permits.
Want to contact me directly? I don't see any reason for that, but here's a tip: I publish enough information to do that in every posting I make. It only takes 3 mouse clicks to get my address into the "To:" line of an email.
