the entire ecosystem is affected by the changes of gravity and radiation caused by the presence of the moon in its orbit around us, from the tides to the blocking effect of the moon shielding us from solar radiation to the rise and fall of gravity due to the alignment/opposition/square relations of the moon relative to the sun
and it affects the magnetic fields as well, there is an entire complex of magnetic flux lines that are constantly changing due to the orbits of the planets and these have big effects on how much radiation hits us both from the sun, from the galaxy around us, and even from such things as jupiter and saturn
