This Seminar on Algae and Metropolitan Wastes was the first national meet- ing devoted solely to this subject. It was part of a continuing program of seminars in the water field at this Center.
The problem of algae is many faceted. Some species are a bane to men on earth, but others are potentially the staff of life of men in space. It is important, however, to consider first those problems most pressing and near at hand, such as the relationship of algae to this Nation's spreading metropolitanism and to the disposal of urban wastes.
The Seminar on Algae and Metropolitan Wastes was limited to discussion of prevention and control of objectionable blooms of algae resulting from enrichment by urban and other wastes.
This is a long standing problem which, as urbanization increases, will become more severe if corrective measures are not developed and applied. We, therefore, regard this report as particularly important and are pleased to present it under the sponsorship of this Center and Compact flourescent lamp and the environment essay Division of Water Supply and Pollution Control of the Public Health Service.
The seminar was attended by registrants representing 27 states and the District of Columbia, and 4 foreign countries. A tour of the Center s was included, and an evening banquet at which Mr. Lynch of the Milwaukee Journal was the principal speaker.
Lynch's talk is presented as the Introduction to this volume. Photo courtesy of Kenneth M. Mackenthun, Wisconsin Committee on Water Pollution. Lynch was delivered as the dinner address of the Seminar. It is pre- sented here to introduce the Transactions because it deals with the basic theme of achieve- ment of better communication between scientist and layman and, indeed, between scientist and scientist.
Toastmaster, scientists, technicans and any others who may have wandered in: They would like a lighter touch, and I agree that it makes for better reading, but I have observed that if I write that way and the editor has to cut my copy to fit his space, it is the facts that go out and the froth that remains.
Scientific and technical people are guilty of the same thing. It is a form of snobbishness and I think that you people cannot af- ford the luxury. As a fulltime reporter on natural resources, the only one that I know of in the newspaper field, I attend more or less technical meetings, work from papers or summaries prepared by technicans and scientists, and read extensively.
And I have observed a very serious lack of communication be- tween scientific and technical people and the public. It is particularly serious in the natural re- sources field, where research and studies must solve problems or develop approaches to them.
When they reach decisions or prepare plans, they spring their ideas on the public and expect them to be received gratefully, and implemented.
This seems to me to be a major reason why pro- gress is so slow toward wise management of re- sources. Usually some changes are involved, some sup- port must be generated, some money must be pro- vided.
People just do not accept changes unless they are convinced of good reasons; they or their representatives just will not dig up money for things they don't understand. Exceptwhen they are fright- ened, I should say. People of foreign countrieswho want American dollars are shrewd enough to learn the American language.
It is important that the people be taken along on the whole trip, and that is not being done. Sauer, University of California geographer and chairman of the international symposium on "Man's Role in Changing the Face of the Earth", said in summation: Now, I don't want to be misunderstood.
There is exactness in scientific and technical terms. Also, my friend, Joe Hickey, professor of wildlife management at the University of Wisconsin, has pointed out to me that scientific papers must be written so that men of different languages may understand them.
But technical and scientific people carry their jargon outside and use it in addressing laymen, sometimes unwittingly, sometimes to be impres- sive.
Even in their own meetings, they are some- times less than comprehensible. A year ago I attended a seminar on aquatic biology here in Cincinnati.
The first session was devoted to radioactivity and the radiobiologists talked a language that the others obviously had difficulty in understanding.
