Limits of Exponential Growth In Nature
True unconstrained exponential growth does not exist in the physical world. In the physical world, every exponential growth curve is really an unfinished sigmoid curve (aka s-curve) as there will be some factor in the system that eventually constrains growth.
We live on planet earth which is a closed system. If you view the inputs and outputs to the earth, you have solar energy and space debris entering and solar energy and space ships exiting. Everything else on earth is stuck within our atmosphere.
If you create a business that sells products, it takes in resources from Earth and outputs products. Most businesses (especially public corporations) have the goal of increasing shareholder earnings. Earnings come from providing value or perceived value to humanity. If the goal of a business is to indefinitely increase shareholder earnings, it must continually grow the amount of value it provides. But businesses take in resources from Earth, which is a finite, mostly closed system. Eventually one of a few failure modes will be reached as exponential growth approaches the constraints of the system. The second and third order effects of these limits are interesting and often neglected.
- The business will run out of input resources (unless the business is capable of recycling its product 100%).
- Because we live in an interconnected system, there are likely other beings or processes that rely on the missing resource, and depleting it will have cascading effects.
- As resources deplete, prices will rise resulting in reduced consumer access or reduced corporate earnings
- We will run out of humans to sell our product to. Every applicable human will own the product.
- We can stop at this point
- We can alter our business models to extract more money for no increased value (Raise prices, subscription models, etc.)
- We can enter an operating model where we sustainably create future users (possibly the most ethical route) by constraining our output at sustainable levels.
- We can start manipulating human perception via marketing (propaganda) to make them think they value the product more than they do. Make them want to purchase two. Build other dependent services on the product to make it more critical.
As we can see, both of these scenarios are not desirable. The only long term solution is to sustainably use resources and be comfortable making profits at the sustainable level of market demand. Unfortunately due to rivalrous games( See
The same principles apply to any type of exponential growth in a closed system. Viruses, bacteria, species population, resource usage, company growth, etc.
