There are maybe a couple hundred
billion galaxies. In our galaxy, there might be 400 billion stars.
About 0.000000045292 percent of the sun's radiation strikes our
planet. Of that, about one third bounces right off, about a quarter
runs the water cycle (ocean currents, clouds, rain, rivers, stuff
like that) and maybe 0.02 percent is used by plants for
photosynthesis. And all our food and also our fuel are minor side
effects of that photosynthetic process. My point is that probably you
shouldn't have invested the energy to tell me my yogurt cup goes in
the recycling, not the trash.
