Environmental Quotes (8 quotes)
Complex organisms cannot be construed as the sum of their genes, nor do genes alone build particular items of anatomy or behavior by them selves. Most genes influence several aspects of anatomy and behavioras they operate through complex interactions with other genes and their products, and with environmental factors both within and outside the developing organism. We fall into a deep error, not just a harmful oversimplification, when we speak of genes for particular items of anatomy or behavior.
Do you realize weve got 250 million years of coal? But coal has got environmental hazards to it, but theresIm convinced, and I know that wetechnology can be developed so we can have zero-emissions coal-fired electricity plants.
Im not sure what solutions well find to deal with all our environmental problems, but Im sure of this: They will be provided by industry; they will be products of technology. Where else can they come from?
Man, the cutting edge of terrestrial life, has no rational alternative but to expand the environmental and resource base beyond earth.
The most important environmental issue is one that is rarely mentioned, and that is the lack of a conservation ethic in our culture.
There is no gene for such unambiguous bits of morphology as your left kneecap or your fingernail ... Hundreds of genes contribute to the building of most body parts and their action is channeled through a kaleidoscopic series of environmental influences: embryonic and postnatal, internal and external. Parts are not translated genes, and selection doesnt even work directly on parts.
We do live in a conceptual trough that encourages such yearning for unknown and romanticized greener pastures of other times. The future doesnt seem promising, if only because we can extrapolate some disquieting present trends in to further deterioration: pollution, nationalism, environmental destruction, and aluminum bats. Therefore, we tend to take refuge in a rose-colored past ... I do not doubt the salutary, even the essential, properties of this curiously adaptive human trait, but we must also record the down side. Legends of past golden ages become impediments when we try to negotiate our current dilemma.
We do not inhabit a perfected world where natural selection ruthlessly scrutinizes all organic structures and then molds them for optimal utility. Organisms inherit a body form and a style of embryonic development; these impose constraint s upon future change and adaptation. In many cases, evolutionary pathways reflect inherited patterns more than current environmental demands. These inheritances constrain, but they also provide opportunity. A potentially minor genetic change ... entails a host of complex, nonadaptive consequences ... What play would evolution have if each structure were built for a restricted purpose and could be used for nothing else? How could humans learn to write if our brain had not evolved for hunting, social cohesion, or whatever, and could not transcend the adaptive boundaries of its original purpose?
