Document Summary
Everything caught in that sieve is something that antibiotics is killing. The things falling down through the sieve is something that has escaped being killed by antibiotics. According to picture, couple of the non-resistant ones make it through, but it disproportion to the blue ones. So in the next generation, we get more of the resistant ones. It keeps going happening with repeated antibiotics application to the point where we end up with pure culture of resistant ones. Energy flows through the system, then it is always lost. You can keep them in the same area. You can set up almost little pawns community, you can put plants and animals inside. The new questions become the observation to fill the process over and over: deformity and decline in amphibian populations: a case study, 20 years ago, a group of kids were out to collect frogs. Half the frogs in the ponds there were looking at, have horrible deformities.
