Electromagnetic explosions… devastating climate change… mysterious diseases… all carving a deadly path across the globe. Could mankind’s biggest threat come from a natural disaster -- or might the cause be something more sinister − something from out of this world?
TARGET EARTH examines our planet’s complex infrastructure and life-support systems and shows how humans are vulnerable to attack from a variety of threats − be it man-made or extraterrestrial. Leading scientists, government officials, military personnel and others explore where Earth’s abundant resources, telecommunications, food and water supplies, weapons and even the human body could be taken over by a hostile force. Are we susceptible to outside control? Could an enemy use our own planet and its natural resources as a weapon against us?
If we discover we’re not alone in the universe, would an alien invasion be likely? Would Earth’s populations unite to fight a common foe - or would human nature place us at odds − against each other?
