Beware simple solutions

Let’s assume you have a mole problem.

Moles keep digging holes in your lawn.

You don’t want to be cruel to nature, ie: use rat poison or exterminators.

You’d like a natural solution.

So you decide to get a mole snake.

Mole snakes eat moles, no more moles, all natural.

Except it turns out snakes are very territorial.

If you move a snake from one geography to another you risk introducing new diseases to the ecosystem, killing existing fauna.

Not only that, it’s illegal to put a snake into the wild.

You thought your simple solution had solved the problem, but turns out you messed up the local habitat, and you broke the law.

Beware simple solutions.
