I finished "Pale Blue Dot" by Carl Sagan.
I'll quickly summaraize this book about the universe:
1. First part of the book argues that there is no God and religion is proven false based on how extremely small the earth is in the universe.
2. A few chapters describing all the dust, metal, gasses, and current, past and future environmental conditions of the planets of our solar system.
3. Humans are going to cause their own extinction because we have technology without wisdom.
4. The ozone is depleting. Climate change is coming. We're all doomed.
5. For humans to survive, we have to colonize other planets and asteroids.
6. We should be able to conquer space travel by the 22nd century.
7. There's a small chance the human species destroys itself as soon as 2006, but certainly not long after that. (Book was written in 1994).
8. If we do make it to space before we go extinct, we'll mess space up as much as we have the earth unless we become a much better race of people.
There are several references to things expected to happen "in the next few decades", which is interesting considering the book was written 3 decades ago. Geopolitically and based on world events, it sounds like it could have been written today. Apparently we don't get along with others in 2025 any better than we did in 1994.
