There's always the danger when you have influenzas that infect chickens, that when you have the close quarters of chickens spreading from one to another and occasionally a human coming into close contact, that there will be the jumping of species from a chicken to a human. This is not something new.
He who is without a newspaper is cut off from his species.
The world has not yet reached the point which, in my view, is an essential condition for the survival of our human species: access by all the peoples to the material resources of this planet.
Evolution doesn't care whether you believe in it or not, no more than gravity does. I want to rekindle excitement over what we've achieved as a species with the space program. We can't afford to regress back to the days of superstition.
I don't think there was a thunderclap or a divine spark that suddenly made one species smart. You can see, in our ancestors, there was a gradual expansion of the brain; there was an expansion of the complexity of tools.
We're the only species who follow unstable leaders. This is true - it has little to do with America - around the world, pack leaders are unstable. Animals don't follow that.
It has adopted the geometry most advantageous to the species or, in other words, the most convenient.
In every advanced mammalian species that survives and thrives, a common anthropological characteristic is the fierce behavior of the adult female of the species when she senses a threat to her cubs. The lioness, the tigress and the mama bear are all examples.
Shelters, conservationists, those concerned about unnecessary cruelty toward the animals we eat, and people working against species extinction fight to preserve the true riches of our planet, our real inheritance. These are big, critical goals.
Going to Mars would evolve humankind into a two-planet species.
The unpredictability of the weather, the increasing possibility of intelligence introducing a species more powerful than ours, the growing uncertainty that animals can or should be slaughtered for our pleasure, has led many of us to start asking more complex questions about what is and isn't normal.
While many alien species are harmless, others pose expensive threats to seas and fields and forests.
Since it is one of the great attributes of our species to be susceptible of improvement and capable of experiencing the most beneficial changes, for this reason what are vulgarly called 'venerable establishments' will often range themselves in opposition to the best interests of the community.
It is a drastic mistake to eliminate the provisions that have to do with the protection of habitat for endangered species. It is my opinion that the Endangered Species Act is 99 percent about protecting critical habitat.
Forecasting is simply not a strength of the species; we are much better with tools and narrative storytelling.
