"Plant a few trees."
Generally, I try to plant 10-20/ year, purchased at the school tree sale; last 2 years, I haven't, due to the drought. I also collect acorns, buckeyes, and bay seeds, and scatter them in the fall. Even planted 3 redwoods behind the Grange.
"Insignificant."
Not insignificant.
Andy Lacis Writes to Steve Koonin
Steven,
Physicists should take the time to understand their physics better.
Only 1% to 2% . . . that may sound small and insignificant . . . but it isn’t.
It is well known that the normal human body temperature is about 310 K. Furthermore, it is also well known that a seemingly small change (up or down) in absolute body temperature by only 1% (3.1 K, or 5.6 F) would make one sicker than a dog, and, that a 2% change in body temperature (up or down by 6.2 K, or 11.2 F) will virtually guarantee a dead body. From this, it should be sufficiently clear that, when viewed in absolute energy terms, the viable margin between life and death in the Earth’s biosphere is remarkably narrow – so much so that a seemingly insignificant 1% to 2% change in the total energy of the global environment will invariably result in serious disruption of the established infrastructure of life in the biosphere....
