102. “Skin color is basically a measure of the local ultraviolet levels, and it is controlled by relatively minor adaptive changes in the genome.”

— Bill Nye

106. “We can become a great generation that leaves our world – our home – in better shape than it is now while raising the quality of life for people everywhere. This will not be easy. We’ve already loaded the atmosphere with enough heat-trapping gases of various kinds to cause our planet to keep warming for many, many years to come. But the situation is far from hopeless.”

— Bill Nye

107. “As fascinating and just plain weird as the deep-sea geothermal vent ecosystems are, they have a great deal less diversity than we find in ecosystems that receive direct sunlight. At deep-sea vents we’ve counted about 1,300 species so far. In the Amazon rain forest, we can find 40,000 species of insects, just insects, in a typical square kilometer. Couple that with trees, monkeys, spiders, and snakes, and the rain forest has thousandfold the diversity.”

— Bill Nye

108. “This is a book about everything. It is about everything I know and about everything I think you should know, too.”

111. “If you’re a creationist reading this, and you want to remark something like, “Well, that’s the way he did it,” I’ll tell you right back, that is just not reasonable, nor is it satisfactory. If we were playing on a team right now, I’d say, “Get your head in the game.”

— Bill Nye

112. “A quantum is the smallest amount of energy there is. So when you hear someone say such and such a thing was or is a “quantum leap,” he or she is actually talking about the smallest possible leap of any kind found in nature. It’s an ironic use of the phrase. However, I’ll grant you that the quantum leap represents an enormous step in thought. In a quantum leap, a particle is either here, or it’s there – in an instant. This discovery changed the world.”

— Bill Nye

113. “We all have DNA, and it’s nearly the same. In rhesus monkeys, we’re close to 93 percent the same. In mice, it’s closer to 90 percent overall.”

119. “We cannot predict the behavior of the whole, complex, connected system. We cannot know what will go wrong or right. However, we can be absolutely certain that by reducing or destroying biodiversity, our world will be less able to adapt. Our farms will be less productive, our water less clean, and our landscape more barren. We will have fewer genetic resources to draw on for medicines, for industrial processes, for future crops. Biodiversity.”

— Bill Nye

120. “That line of reasoning also leads to questions – but they’re the exasperating kind. If there was a designer, why did he or she or it create all those fossils of things that aren’t living anymore? Why did the designer put all these chemical substitutions of radioactive elements in with nonradioactive elements? Why did a designer program in this continual change that we observe in the fossil record, if he or she assembled the whole system at once? In short, why mess around with all this messiness?”

— Bill Nye

121. “We have to reengineer our technology, energy source by energy source – the things we really can control – not try to reengineer the whole planet. Our unintentional effect on the planet is how we got into this mess in the first place. We have to learn how to overcome the Second Law of Thermodynamics and find brilliant new ways of making energy without drowning in carbon.”

— Bill Nye

122. “Our ancestors who did not have a fear of heights, who did not have a fear of eating something poisonous, who did not have a fear of venomous snakes and spiders, who were not afraid of drowning, well – they’re dead.”

— Bill Nye

129. “Since the landmark 1972 paper by Gould and Eldredge, many studies have been done both with real populations and with mathematical simulations. The results explain why evolution appears both fast and slow: It is both fast and slow. Large populations tend to stay genetically about the same. Paleontologists say populations tend toward stasis. Small ones can diverge quickly into new species.”

— Bill Nye

130. “No other organism on Earth does that. Yes, yes, I understand that dolphins are very smart, but I don’t think they build libraries or even contemplate such a project.”
