Eventually, the Sun will swell to occupy the entire sky as its expansion subsumes the orbit of earth. Earth's surface temperature will rise until it matches the 3,000-degree rarified outer layers of the expanded Sun.... But not to worry.

The humanity and the humility, which are very different than the biological species homo sapiens. Humanity versus homo sapiens - very different things. We are biological creatures, we are animals, no doubt, but when you talk about "humando," you're talking about that particular kind of animals who are aware of their impending extinction, who have the capacity to be sensitive to catastrophe and disaster and calamity and profound crisis.
Along with the possibility of extinction of mankind by nuclear war, the central problem of our age has therefore become the contamination of man's total environment with such substances of incredible potential for harm-substances that accumulate in the tissues of plants and animals and even penetrate the germ cells to shatter or alter the very material of heredity upon which the shape of the future depends.
