Ignoring the pyrographic aspects of the pics, they illustrate the brute force engineering solutions that our society has relied on for too long. Complex engineering of systems tends to create systems that are fracture critical, the space shuttle is a prime example, as cost (and other design factors) prohibits redundancy and resilience. In contrast, ecological systems of sufficient biodiversity have the amazing ability to keep on going and to regenerate itself after a disturbance. Unlike engineering, as ecological systems get more complex, they gain in resilience.
