Read an article where they spiced rabbit genes into birch trees to make them grow faster. It had something to do with the birch tree roots being able to break down land fill garbage. My thought was, great give tree disease a way to bridge the gap.
The other I though was interesting was a salmon farm where they were making them grow twice as big. People complained saying if this gets into nature who knows what it will do to the salmon population. The people doing it scoffed noting they were several miles inland and there was no way the salmon could get out. The debate raged, other people noting that fish eggs could and do stick to duck feet and are carried long distances. One day though, a flood hit the salmon facility and all of the salmon vanished. Perhaps dead, perhaps not.
Science will advance the human race in ways we cant conceive yet, that or it will destroy it first.
