Introductory remarks
BY SIR FREDERICK RUSSELL, F.R.S. Marine Biological Association, The Laboratory, Citadel Hill, Plymouth
The effects that man produces and may produce on his environment, stemming largely from overpopulation and failure to get priorities right, are evident to all. There have been many meetings, national and international, held specially to discuss the problems of pollution in its different aspects. When I was asked to arrange a discussion meeting on the effects of industry on fresh waters and estuaries, it seemed to me that it would be sensible to keep it mainly on a national level so that a general survey of research at present undertaken in Great Britain might be made available.
The finely woven pattern of life in fresh waters and estuaries is most difficult to unravel, and subtle changes in floral and faunal population composition, hardly noticeable at first, may eventually have far-reaching results on the whole pattern. Often long-term observations are necessary before man-made effects can be distin- guished from the natural changes that may occur.
The subject is of course a vast one and it has only been possible, for a two-day meeting, to make a selection, industry being here interpreted in its widest sense to include also sanitation and agriculture. We realize that there are many gaps in the programme, and it is to be hoped that some of these may be filled by speakers in discussion. This is a field of research in which I have myself taken no part, except to produce some long-term field observations on natural changes in the sea. We are fortunate today in our chairman and speakers to whom I am most grateful for their willing cooperation, and especially to my colleague H. C. Gilson. I hope that all attending this meeting will find it interesting and profitable.
