I don't think we are going to become extinct. We're very clever and extremely resourceful - and we will find ways of preserving ourselves, of that I'm sure. But whether our lives will be as rich as they are now is another question.
Mauna Kea from Hilo has a shapely aspect, for its top is broken into peaks, said to be the craters of extinct volcanoes, but my eyes seek the dome-like curve of Mauna Loa with far deeper interest, for it is as yet an unfinished mountain.
Certainly paleontologists have found samples of an extremely small fraction, only, of the earth's extinct species, and even for groups that are most readily preserved and found as fossils they can never expect to find more than a fraction.
Whether the prayer of Seneca was granted we do not know; but, as we do not again hear of Marcus, it is probable that he died before his father, and that the line of Seneca, like that of so many great men, became extinct in the second generation.
Global climate change has become entangled with the problem of invasive species. A warmer climate could allow some invaders to spread farther, while causing native organisms to go extinct in their traditional habitats and making room for invaders.
Aside from bringing back extinct species, reanimation could help living ones by restoring lost genetic diversity. The Tasmanian devil (aka Sarcophilus harrisii) is so inbred at this point that most species members can exchange tumor cells without rejection.
Most people know that forests are the lungs of our planet, literally playing a critical role in every breath we take. And that they're also home to incredible animals like the orangutan and elephant, which will go extinct if we keep cutting down their forests.
What the fossil record does do is to force us to contemplate our place on the planet. We are but one species of several hominids that inhabited Planet Earth, and like our distant cousins who went extinct fairly recently, our time on Planet Earth is also finite.
All cannot rule, nor can all be ruled. All cannot plow, nor can all sow, nor reap. No more can all neglect such employments, else the race would become extinct. Each has his business to perform, his part to act. It is a duty he owes to the rest as well as to himself.
My first attraction to writing novels was the plot, that almost extinct animal. Those novels I read which made me want to be a novelist were long, always plotted, novels - not just Victorian novels, but also those of my New England ancestors: Herman Melville and Nathaniel Hawthorne.
The Americans will never solve the Indian problem till the Indian is extinct. They have treated them after a fashion which has intensified their treachery and 'devilry' as enemies, and as friends reduces them to a degraded pauperism, devoid of the very first elements of civilization.
Every species becomes extinct; at some point, we will go extinct. The question is, as Homo sapiens, are we going to be able to adapt to the change that we're actually part of? We're causing such dramatic changes to the planet, so yes, you do stop and think, 'I wonder where we're headed.'
I think when you work on fossils, and you realize that a species is there, and it's abundant for quite a long period of time, and then at some point it's no longer there - and so, when you look at that bigger picture, yes, you realize that either you change and adapt, or, as a species, you go extinct.
You don't know how to fix the holes in our ozone layer. You don't know how to bring salmon back up a dead stream. You don't know how to bring back an animal now extinct. And you can't bring back forests that once grew where there is now desert. If you don't know how to fix it, please stop breaking it!
Autumn is much redder in North America and east Asia than it is in northern Europe, and this can't be explained by temperature differences alone. These areas also have a greater proportion of ancient tree lineages surviving: trees have gone extinct at a higher rate in Europe compared with those other areas.
At the close of my visit, my Hawaiian friends urged me strongly to publish my impressions and experiences, on the ground that the best books already existing, besides being old, treat chiefly of aboriginal customs and habits now extinct, and of the introduction of Christianity and subsequent historical events.
CRISPR-enabled 'gene drives' enable us to make changes to the germ-line of organisms permanent such that changes spread through the entire wild population, including making species extinct on demand. Unlike nuclear weapons such technologies are not complex, expensive, and able to be kept secret for a long time.
Life is insanely robust, though we can make species go extinct, and this is the bad thing. So I always make the point that you can't say, 'Is it too late?' That is the terrible question, because either answer promotes inaction. If it's too late, you don't need to act; if it's not too late, you don't need to act.
Asteroids have us in our sight. The dinosaurs didn't have a space program, so they're not here to talk about this problem. We are, and we have the power to do something about it. I don't want to be the embarrassment of the galaxy, to have had the power to deflect an asteroid, and then not, and end up going extinct.
Several times in Earth's history, rapid global warming occurred, apparently spurred by amplifying feedbacks. In each case, more than half of plant and animal species became extinct. New species came into being over tens and hundreds of thousands of years. But these are time scales and generations that we cannot imagine.
1925's 'The Lost World' is... really, everything a dinosaur movie should be. Like a dinosaur, this classic was once extinct too, existing as mere fragmentary footage and stills, but cinemaphile fossil-hunters have painstakingly excavated bits and pieces from obscure archives and assembled them into a nearly-complete animal.
