Everything is part of an ecosystem, even office buildings. Nature shows us that a healthy ecosystem, one that survives shocks, is a diverse ecosystem. Diverse ecosystems find niches faster and niches grow over time to turn into major driving forces. They absorb shocks as new things enter since not all parts react the same or on the same timeline. Diversity is key to long term health. This is why monopolies are bad, this is why we should be looking for every kind of diversity we can in every problem. I have gotten to the point that when I see large scale problems I start looking for where the diversity is low and that is almost always the issue. Politics bad? Maybe if we had more than two choices things would be better. Housing bad? Maybe if we had more mixed use things would be better. Energy segment issues? Look at how fast the energy segment is improving now that renewables have finally been added to the ecosystem and we have more choices. Etc, etc etc.
