Project Syndicate: Bjorn Lomborg on Scaring People Into Action
PRAGUE – Campaigners on important but complex issues, annoyed by the length of time required for public deliberations, often react by exaggerating their claims, hoping to force a single solution to the forefront of public debate. But, however well intentioned, scaring the public into a predetermined solution often backfires: when people eventually realize that they have been misled, they lose confidence and interest.
Last month, there were two examples of this in a single week. On September 19, the French researcher Gilles-Eric Séralini attempted to fuel public opposition to genetically modified foods by showing the public how GM corn, with and without the pesticide Roundup, caused huge tumors and early death in 200 rats that had consumed it over two years. ...
Lomborg highlights the throughly bogus nature of the study and it funding and notes:
Moreover, Séralini’s results contradict the latest meta-study of 24 long-term studies (up to two years and five generations), which found that the data do “not suggest any health hazards” and display “no statistically significant differences” between GM and conventional food.
Why is this important?
This debacle matters because many GM crops provide tangible benefits for people and the environment. They enable farmers to produce higher yields with fewer inputs (such as pesticides), so that more food can be produced from existing farmland. That, in turn, implies less human encroachment into natural ecosystems, enabling greater biodiversity. But, of course, Séralini’s pictures of cancer-addled rats munching GM corn have instead been burned into the public imagination.
Then there was a climate change report:
The Séralini fiasco was only a week old when, on September 26, the Climate Vulnerability Forum, a group of countries led by Bangladesh, launched the second edition of its Global Vulnerability Monitor. Headlines about the launch were truly alarming: Over the next 18 years, global warming would kill 100 million people and cost the economy upwards of $6.7 trillion annually.
These public messages were highly misleading – and clearly intended to shock and disturb. The vast majority of deaths discussed in the report did not actually result from global warming. Outdoor air pollution – caused by fossil-fuel combustion, not by global warming – contributed to 30% of all deaths cited in the study. And 60% of the total deaths reflect the burning of biomass (such as animal dung and crop residues) for cooking and heating, which has no relation to either fossil fuels or global warming.
In total, the study exaggerated more than 12-fold the number of deaths that could possibly be attributed to climate change, and it more than quadrupled the potential economic costs, simply to grab attention. ...
He goes on:
Likewise, overcoming the burden of indoor air pollution will happen only when people can use kerosene, propane, and grid-based electricity. If the Global Vulnerability Monitor’s recommendation to cut back on fossil fuels were taken seriously, the result would be slower economic growth and continued reliance on dung, cardboard, and other low-grade fuels, thereby prolonging the suffering that results from indoor air pollution.
When confronted with their exaggerations, the authors claimed that “if you reduce hazardous air pollution, it is difficult to not also reduce warming emissions.” But, for both indoor and outdoor air pollution, the opposite is more likely true: lower carbon emissions would mean more air pollution deaths.
When scare tactics replace scientific debate, whether about GM crops or climate change, nothing good can come of it. We all deserve better.
