India, Oct. 2 -- Plastic. We have all seen it. Felt it. Used it. Learned how it's produced. Some of us have fallen in love with it, and some of us have blamed old people for society's rather prolonged dalliance with it. We have shopped using plastic bags, shared drinks using plastic straws, flicked on and off plastic switches. We have sat in plastic chairs, played with and smashed plastic toys, communicated using phones having plastic bodies, banged our plastic keyboards hard when we had had enough of slow peripherals. And a few of us have sold plastic eggs to the suckers of the world (what's life without a little conning?). And yet we are nowhere near mentioning the gazillion ways in which humans have become all but plastic.

But why shoul...
