Yes, but the Vinyls with their ultrahigh fertility rate will continue to insure we will have Polyvinyls for a long time to come.
Right up until the entire country is protecting the environment by capping all the oil wells and relying solely (solarly?)on solar, wind, and other boondoggle methods of power production.
When that happens all the Vinyls will starve to death.
*snif-snif*
Oh how sad to die when one is so young and cute. (Pogo Possum)
About the vinyls dying..
To quote Billy Joel- only the good die young.
(I like that song)
