I am still wondering about the role of nitrogen, and here is a report on that topic from Mongabay. We are definitely doing a lot of very stupid things on a large scale that is wreaking havoc in the environment.
i grieve for Gail's trees--you deserve the kindest blessings for your witness to them. i've been worrying for our local trees every late winter for a few years now as they look more and more like victims of some Orc attack--i still have this childish notion that if someone only notices and cares, that will help them come back to bud and leaf every spring, the poor beautiful massive beings, so i walk through sometimes, touching the trunks and saying hello.
last, as usual, your post this week performs wonderfully as an ink-blot upon which to see a nice selection of current feelings/hopes/fears projected. i can empathize with most of them. i offer a very old poem, in keeping with my comment on Lord Soil:
Keep walking, though there is no place to get to.
Don't try to see through the distances.
That's not for human beings.
Move within, but don't move the way fear
makes you move.
Today, like every other day, we wake up empty
Don't open the door to the study
and begin reading.
Take down a musical instrument.
Let the beauty we love be what we do.
Let the beauty we love
be what we do.
There are hundreds of ways to kneel and kiss the ground.
