What does Carson mean when she writes that the
poisoning is "irreversible"?
Chemicals or fallout stay in an organism until
its death and are then passed on.
Chemicals have a temporary effect on the
health of living organisms.
Living things are unable to process some
chemicals, but they are not harmful.
The most alarming of all man's assault
the environment is the contamination
earth, rivers, and sea with dangerous a
even lethal materials. This pollution is
most part irrecoverable; the chain of ev
initiates not only in the world that mus
support life but in living tissues is fort
most part irreversible. In this now unix
contamination of the environment, che
are the sinister and little-recognized pa
of radiation in changing the very natur
world - the very nature of life. Strontiu
