More friendly flora?

I like the bacteria that live in my gut. They're supposed to be there. :-)

Not so sure about Pseudomonas fluorescens, a bacterium that scientists are talking about adding to Lake Mead to kill off an invasive species of mussels. These tricky little guys cause problems for the Vegas water supply by clogging water intakes and damaging pumps, and they seal themselves in their shells if they detect poisons in their vicinity. They remain vulnerable to P. fluorescens, however.

Hmm. Might work. Or we might be smarter than we think we are and end up with some other problem.

There was an old woman who swallowed a cat.
She swallowed the cat to eat the bird.
She swallowed the bird to eat the spider.
She swallowed the spider to eat the fly.
I don't know why... she swallowed the fly.
I guess she'll die.
