A Quote by David Suzuki

We have altered the physical, chemical and biological properties of the planet on a geological scale. We have left no part of the globe untouched. — © David Suzuki
We have altered the physical, chemical and biological properties of the planet on a geological scale. We have left no part of the globe untouched.
The upshot is that most philosophers of biology now hold that biological properties supervene on physical properties (where supervenience is taken to include some kind of "in virtue of" relation), and that fitness and other biological properties are not identical with physical properties.
Scientists and supercomputers have amplified our ability to look ahead. For decades, experts have warned us that human numbers, technology, hyper-consumption and a global economy are altering the chemical, geological, and biological properties of the biosphere.
But the prospects of designing chemical plants for industrial scale chemical processes seemed far less interesting than the chemical events that occur in biological systems.
Any attempt to reduce the complex properties of biological organisms or of nervous systems or of human brains to simple physical and chemical systems is foolish.
The last UN weapons inspectors left Iraq in October of 1998. We are confident that Saddam Hussein retains some stockpiles of chemical and biological weapons, and that he has since embarked on a crash course to build up his chemical and biological warfare capabilities. Intelligence reports indicate that he is seeking nuclear weapons.
The planet isn't improvising, it's creating dynamic tensions between complex living systems in a planetary choreography, a balancing act between physical, chemical, biological, environmental, and human components.
It's a pity we're still officially living in an age called the Holocene. The Anthropocene - human dominance of biological, chemical and geological processes on Earth - is already an undeniable reality.
When human beings have been fascinated by the contemplation of their own hearts, the more intricate biological pattern of the female has become a model for the artist, the mystic, and the saint. When mankind turns instead to what can be done, altered, built, invented, in the outer world, all natural properties of men, animals, or metals become handicaps to be altered rather than clues to be followed.
In the four years since the inspectors left, intelligence reports show that Saddam Hussein has worked to rebuild his chemical and biological weapon stock, his missile delivery capability, and his nuclear program. He has also given aid, comfort, and sanctuary to terrorists, including al Qaeda members... It is clear, however, that if left unchecked, Saddam Hussein will continue to increase his capacity to wage biological and chemical warfare, and will keep trying to develop nuclear weapons.
Pluto is still active four and a half billion years into its history. It was expected that small planets like Pluto would cool off long ago and not still be showing geological activity. Pluto is, in fact, showing numerous examples of geological activity on a massive scale across the planet.
The mechanist is intimately convinced that a precise knowledge of the chemical constitution, structure, and properties of the various organelles of a cell will solve biological problems. This will come in a few centuries. For the time being, the biologist has to face such concepts as orienting forces or morphogenetic fields. Owing to the scarcity of chemical data and to the complexity of life, and despite the progresses of biochemistry, the biologist is still threatened with vertigo.
I also assume that they are not simply the physical properties of things as now conceived by physical science. Instead, they are ecological, in the sense that they are properties of the environment relative to an animal.
We expected, I expected to find actual usable, chemical or biological weapons after we entered Iraq. But I have to accept, as the months have passed, it seems increasingly clear that at the time of invasion, Saddam did not have stockpiles of chemical or biological weapons ready to deploy.
Cellulose has physical and chemical properties that make it difficult to access and difficult to break down.
In the visible world, the Milky Way is a tiny fragment; within this fragment, the solar system is an infinitesimal speck, and of this speck our planet is a microscopic dot. On this dot, tiny lumps of impure carbon and water, of complicated structure, with somewhat unusual physical and chemical properties, crawl about for a few years, until they are dissolved again into the elements of which they are compounded.
The first true antibiotic to be derived from a culture of an actinomyces was isolated in our department in 1940. The organism, Actinomyces antibioticus, yielded a substance which was designated as actinomycin. It was soon crystallized, and its chemical and biological properties were established.
