Dinosaurs had an unbelievably long run. More importantly, there has been no indication that dinosaurs were in trouble when a meteor the size of Mt. Everest decided to hit just off the coast of what is now the Yucatan Peninsula. This book does not examine why the dinosaurs were successful except in the relationship of what humans do. The book looks at various area such as nature, industrialization, and agriculture. For instance, dinosaurs did not build homes, people do. Over a long period of time, what difference does that make? If you want to look at an extremely long period of time you will have to read my other book, "Hard Drive Back-up". I hope this book entertains but I also hope it helps make you think and compare what was truly successful to what we are doing today.
