How much faith do you have in humanity as a whole to be able to expand and secure its survival outside of our home planet by colonising other worlds? Do you believe water/food crises, uncontrollable population growth, environmental destruction, war, corruption, religious fanaticism, ecomonic deterioration, disease, climate change, cataclysmic weather and humanity's massive and insatiable appetite for resource consumption will ensure humanity never gets to develop the technology and ability to colonise other worlds and doom us to die here on Earth?
