...where else are the accumulating? The opposite (Alleged) effect to DDT.
Birds reinvent the mallet to enable the chicks to escape from the Egg.
Seriously, you do have a very good point there.

Well, you know, the meek will inherit the Earth. We just didn’t know until now how it could come about...

There are challenges ahead, of course. Nobody has discovered an efficient way to harvest spider silk, although not for lack of trying. Hummingbirds have been harvesting spider silk for ages...

A single layer of graphite has the carbon atoms arranged in hexagons.
It you magnified it A LOT it would look a bit like a sheet of chicken wire fencing.
Now imagine you cut off a few inches of chicken wire and rolled it into a tube and lined up and welded the raw ends.
You'd have a tough, flexible tube.
Shrink it back down and make the wires strong carbon-carbon bonds, and you've got one heck of a robust material!
