What I am going to tell you today may seem difficult to believe. Indeed, being an optimist, I find it hard bo believe myself. But, being a scientist, I have tried to objactively analyze the data and have come to the following two conclusions: The first is that the oceans are beginning to die from chemical pollution; the second--and even more disturbing---is that NOTHING is being done about it; very few people know about it; -- no one is watching the world. This chemical contamination ias begun to wipe out some species of oceanic birds. If left uncontrolled it will result in the death of the oceans.
This contamination is not only the very visible oil pol lution we are hearing so much about these days. What I'm most concerned about, and what I want to discuss today, ia the in visible contamination of the oceans by long-lived chemicals. For the remainder of this talk I want to discuss fir(at the problem, and second, what can be done about it.
I fully realize that this whole concept of oce anic contamination is difficult to imagine. Let's face it; when we talk of pollution of the seemingly endless oceans, we are really talking about global pollution. But in fact, there are already two well-documented examples of the chemical contamination of our entire planet.
The first was that resulting from Strontium.90 (Sr90) and other isotopes released during nuclear testing. How did it happen? First, this radioactive isotope was release d into the atmosphere. There it was carried by global wind pat terns all

over the earth to come down with rain and dust as radioactive fallout. Because Strontium is almost like calcium, it was
concentrated by living organisms and thus got into our food. When we ate this contaminated food, the Sr^O, being like calcium,
tended to concentrate in bone. Being radioactive, continued exposure to this radiation would have resulted in an increased incidence of cancer. Because of this global ccntamination by Sr^O and other radioactive elements, an internetional agreement
was made to stop atmospheric nuclear testing.
The next example--which is still all too current--is the
global pollution by DDT. How did this happen? First of all DDT is also a long-lived chemical--just as the half-life of
is 19 years, the half-life for DDT is between 10 and 30
years. Secondly, DDT is also released into this air during
spraying or evaporates into the air after spraying. It too, is concentrated by living organisms and tends jto increase in
concentration higher up in the food chain. How does it get to such high levels? Fijicst, it is fat-
soluble, and even if present in minute amounts, the marine animals concentrate it--they literally scoop iit up--from the water. Second, it is not easily metabolized, The organisms
cannot break it down or excrete it. Thus, DD1 gets into microscopic sea plants. The sea plants--with their DDT--are eaten by small fish. These fish--with their IDT--are eaten by still larger fish. Thus the DDT level gete higher and the highest levels are in those animals at the top3 of food chains --
such as the fish-eating birds.

T7Pm= reasons this contamination is of such concern is that
DDT is
. poisonous chemical--which, of course, is the reason it
is used --
an insecticide. The farmer assumes Lt stays in or
near thei^ cield where he sprayed it. The contam|ination of the

oceans;
rout instead the bulk of government surv eillance was with
freshwarr-rr and terrestrial organisms.
Ttrros. , the first solid evidence for the ma|5 sive extent of
this glc_~---x.l pollution came from the laboratories of several
universe~----p scientists, who looked beyond the imiijnediate and
more drozsstic fish and bird kills. Through thei r investigations

The most extensive survey has been m ade along the
