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.
