There's a clever commercial out now that depicts a middle aged caucasian guy that has been converted to some psuedo-buddhism practice or preserving life, he returns a spider to a plant, puts a floundering fish back into the pond . . . etc. then he sneezes and uses an "anti-bacterial" Kleenex tissue that "kills millions of germs."

In 'Stranger From a Strange Land" the title character is first repulsed at walking on living grass . . . but then comes to understand (grok) that the grass' existence includes being stepped on.
