Should We Colonize Other Planets? Exploring New Human Frontiers for Space Exploration and Future Survival

This book is an extended essay, or thesis might be a better word, regarding a specific topic. The author has composed the essay from his individual perspective and has clearly demonstrated extensive thought and consideration for the topic. The question is a "big" one, but as with many big questions, it's easy to arrive at a conclusion with which others might disagree. "Should marijuana be legalized" is one of those questions around which one could write an essay but with which there will always be those who disagree no matter your hypothesis.My goal here was to take note of but essentially ignore the positions while utilizing the essay as a constructive method for formulating my own thoughts on the matter. For instance, while I had already considered the fact that Earth's lifespan is finite, I hadn't considered the fact that our species' lifespan is potentially far more limited, even without any catastrophic interference or dramatic societal errors in judgment. And of course sending a large colony of humans off to another planet will likely result in genetic variations taking hold within the colony while the parent group goes in another direction. If ultimately that group has become another species, what was your point of colonizing another location? Did you meet your goals? From these perspectives, the author provides a well directed course along which you can fly while making your own decisions as you travel. And it's a fascinating and interesting course. The book is fairly short and can be consumed over a two hour airline flight, then thought about repetitively thereafter.
