Fifty two years ago, on this day, April 5, 1971, a UK scientist gave an overview of “pollution in context to an assembled audience of the great and the good (and the mediocre and middling)
POLLUTION IN CONTEXT by MARTIN IV. HOLDGATE , PhD Director of the Central Unit of Environmental Pollution , Department of the Environment,* delivered on Monday 5th April 1971 Journal of the Royal Society of Arts, Vol. 119, No. 5180 (JULY 1971), pp. 529-542

1. Naturalness One broad classification can be based on ‘naturalness’. Some substances that can be ‘pollutants’ occur naturally, and are widely dispersed in the world. Some are essential to life. Carbon dioxide is a good example: it is the foundation of photosynthesis by which green plants using solar energy create sugars. Without CO2 in the air, life as we know it could not exist on this planet. And much CO2 enters the air naturally through the respiration of living things and organic decay. Since 1890, man, burning fossil fuels (which are themselves a residue of undecomposed organic carbon that escaped conversion to CO2 long ago) has raised the CO2 level of the atmosphere from around 290 to 320 parts per million but in that same period the natural input has certainly greatly exceeded the artificial
(Holdgate, 1971: 530)
The amount of carbon dioxide in the air was roughly 327.8ppm. As of 2023 it is 419ppm, but check here for daily measures.
The context was
Everyone was talking about pollution – air, water, noise, you name it. Doomwatch was on the tellie, and the European Year of Conservation had just finished, with the big UN conference in Stockholm just over a year away.
What I think we can learn from this
Again, none of this is a secret. “We” “knew.” And then pushed it out of our minds, and then it had to be pushed back in. Then was pushed out again.
This has a name – the Issue Attention Cycle, as per Downs in 1972. But Robert Heilbroner had predicted this would be the case as early as April 1970…
What happened next
The attention died down, as people got bored/used to things, and then other (economic) problems came along.
Martin Holdgate, who is still alive, had a storied career. He was Chief Biologist to the British Antarctic Survey, then research director of the Nature Conservancy Council and, for eighteen years, Chief Scientist and head of research at the Department of the Environment.[1] Subsequently, he was Director General of the International Union for Conservation of Nature.”
What do you think? Does this pass the ‘so what?’ threshold? Have I got facts wrong? Interpretation wrong? Please do comment on this post, unless you are a denialist, obvs...
