¥ Endocrine disruption refers to the hormone-altering effects of
certain chemical
substances on animal endocrine systems that impair reproduction or
develop-
ment. Endocrine-disrupting chemicals alter the messages sent through
hormones,
an effect that can cause permanent functional changes to a developing
animal,
impair reproduction, and can increase susceptibility to cancer in
adult animals.
Many commonly used pesticides are suspected endocrine disruptors (see
Appen-
dix 1). The rapid decline in bird populations in the 1960s and 1970s
caused by
organochlorine pesticides such as DDT was due to endocrine-disrupting
effects.
Certain pesticides have been shown to mimic or block the action of
estrogen, the
primary female hormone. Exposure of developing animals to these
chemicals, in
utero or in eggs, has been associated with feminization or
demasculinization of
male offspring or masculinization of female offspring. For example,
alligator
eggs from Lake Apopka in Florida produced nearly all female offspring
due to
exposure to high concentrations of the pesticide dicofol.9 Some
pesticides block
the action of androgens (male hormones) as well. In humans, increases
in repro-
ductive abnormalities of newborn children and lowered sperm counts in
men
have been linked to exposures to endocrine-disrupting chemicals.

crine-disrupting pesticides in California are shown in the sidebar.

"Acts of creation are ordinarily reserved for gods and poets,
but humbler folk may circumvent this restriction if they know how.
To plant a pine, for example, one need be neither god nor poet;
one need only own a good shovel. By virtue of this curious loophole in the rules,
any clodhopper may say: Let there be a tree--and there will be one"
