Generally speaking, I think advertisements have dropped in quality over the years. The young blood they are bringing in today have the vision and foresight of about 2 ft. past their desk. I'm pretty sure this all sounded good back at the cubicle. "Wouldn't it be funny if.." goes a long way when you're young.
Right now Sony Pictures is doing a similar thing with the fear of 2012. You can join the lottery to one of the few to be saved. If you don't pay attention, you'll miss the little link for the movie page at the bottom. There are even some commercials on TV leading you to the page. http://www.instituteforhumancontinuity.org/
This is an advertising technique similar to LOST's internet campaign.
I would really like to see the emails myself to see if either Toyota was too far out there or if she was too naive. Either could happen. In her favor, I would not expect a company that has been promoting Earth, Nature and Humanity to pull out this kind of garbage.
