Playing God with Nature?
There are ALWAYS unforeseen consequences, you know? Case in point: Playing God in Yellowstone. It's been over two decades now, but that book chronicles the attempts of man to play God and manage Nature, to the detriment of Nature.
Building dams up and down the west coast destroyed salmon habitat; creating sea walls have altered the natural sand migration process causing some beaches to disappear while others grow; filling in marsh land for agriculture eliminated natural buffers, filtration and critical wildlife ecosystems.
It takes, in some cases, decades to understand the consequences of our actions; it also may require several decades for Nature to repair itself from the damage man has created.
