There can be no doubt that the existing Fauna and Flora is but the last term of a long series of equally numerous contemporary species, which have succeeded one another, by the slow and gradual substitution of species for species, in the vast interva...
Yes, the human race is a small species in an infinite universe filled with many other planets and many other things, but though small; this race is bearer of very great and big things: Destiny, Virtue, Hope, Love... and that's what makes this species...
The human species' foremost task and unshakable duty is survival.
If current technological processes continue without change, the environment will change, and we, the human species, will either have to mutate or even die, to disappear, as many species have disappeared.
The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.
As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species.
Don't you know how hopelessly I need you?
We're endangered by our own success.
There's so much plastic in this culture that vinyl leopard skin is becoming an endangered synthetic.
No protracted war can fail to endanger the freedom of a democratic country.
The whale is endangered, while the ant continues to do just fine.
Liberty may be endangered by the abuse of liberty, but also by the abuse of power.

Crime is a fact of the human species, a fact of that species alone, but it is above all the secret aspect, impenetrable and hidden. Crime hides, and by far the most terrifying things are those which elude us.
Moreover, all our knowledge of organic remains teaches us, that species have a definite existence, and a centralization in geological time as well as in geographical space, and that no species is repeated in time.
I think that my main criticism in that book was directed at the general assumption that adaptation characterizes populations and species, rather than simply the individuals in the populations and species.
An island, on the other hand, is small. There are fewer species, and the competition for survival has never reached anything like the pitch that it does on the mainland. Species are only as tough as they need to be, life is much quieter and more sett...
Vaccines save lives; fear endangers them. It's a simple message parents need to keep hearing.
Perceptual reality is different for different species. In certain species it is a mode of observation, so what we call scientific fact is actually not ultimate truth, it is perceptual experience, and it's a mode of observation.
I fully support the goal of species protection and conservation and believe that recovery and ultimately delisting of species should be the U.S. Fish and Wildlife Service's top priority under ESA.
Eurasia ended up with the most domesticated animal species in part because it's the world's largest land mass and offered the most wild species to begin with.
