here's an idea for a business that would have pretty much NO chance of making money whatsoever, but people would love it: Loach rental service. if your tank is infested with snails, but it's not big enough to host a shoal of loaches, they loach rental team comes in, puts them in your tank, and then picks them up once they've dealt with the problem.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
