If you take water from the ground and there is no replenishment of the aquafer, your wells go dry.

If you grow crops that deplete the soil and don't replenish the soil nutrients, your farm fails.

If you take money from a business and don't reinvest in it, your business goes belly up.

There is no such thing as an "open ended cycle."

What's hard about these things? Take a little, put a little back in, and you're okay. Take it all and don't put any back, you're dog food. What part of "growth" don't you understand?
