Even with all our modern technology, we are still helpless when nature unleashes its fury through natural disasters. By creating a collective global system to accurately predict and possibly prevent natural disasters like earthquakes and tsunamis would be of unprecedented benefit to survival of humanity. Such a technological solution would detect a potential disaster and send out warnings, giving ample time for evacuation. Then it would work to avert the disaster by using all available technology to effectively counteract. So countless lives would easily be saved.
