How common is lead on earth or in living things?
Unfortunately due to the pervasive motor vehicle, a thin layer of lead is almost uniform in most countries. From the (now mainly abandoned) practice of using tetra-ethyl lead as an anti-knock compound in petrol. Otherwise, lead was used in house paint, and still has a use in lead-acid vehicle batteries. Lead is used as a malleable flashing to waterproof buildings, and is used in solders, bullets, boat keels and many other uses.. Lead is also used to give crystal glass its high refractive index, and it helps make glass more ductile, so a TV CRT will have several pounds of lead in the glass. Lead is a poison, and causes mental retardation. It tastes sweet (lead acetate) and in New Zealand it caused high blood lead levels in the excessively curious alpine parrot, the Kea, which chews lead-head nails.
