The first edition of THE HUMAN POPULATION TSUNAMI was available 2013-2015 and received much constructive criticism. This is the fully revised second edition. During 2015, more than 600,000 people migrated into Europe from Asia and Africa. Most of them were fleeing wars or tyranny, and they deserve a sympathetic welcome, but many were simply seeking a better life. A few were determined to destroy European democracies and impose their own totalitarian form of government. These waves of migrants are only tiny ripples compared with what will happen in future years because every two seconds five more babies are born than people die. That's 8,000,000 more people every five weeks - about the population of London or New York. Is Europe ready to accept perhaps a million refugees in 2016, and maybe two million the year after? Over population is the ultimate driving force of war and tyranny. Before facing that stark fact, we must think about thinking. Accurate human thought is hog-tied by feelings, rules and taboos. This book examines all three. In doing so, we are confronted by what it really is to be a human being. Having understood that, the natures of the individual, immortality and morality become obvious. From that philosophical base we can plan the future for all people. Rational thought is the common ground between all religions and convictions; let us meet on it, and begin by criticising the revision of this book.
