Stuart Smith's letter (“Accusations without evidence,” Jan. 18) is a perfect example on how "science" is tossed around to make points that have nothing to do with science.
Mr. Smith disputes Mr. Smithers' assertions (“Climate and environmental downside of vineyards,” Jan. 10) that assigned blame to the proliferation of hillside vineyards for the degradation of our environment.
Mr. Smith cites the improved water quality in the Napa River as scientific proof that the concurrent proliferation of hillside vineyards is the cause of this improvement. Quite a leap in scientific reasoning, let alone proof.
Second, while Mr. Smith's advantageous comparison of vineyards to Napa Valley forests in terms of propensity to fire is correct, it is unfair because it is one to ill managed - not well managed - forests as Napa's are. Given all the other scientifically proven environmental advantages forests have over hillside vineyards (superior erosion control and carbon sequestration, slower runoff and water table replenishment), the logical course of action is not to replace them with vineyards but rather manage them properly.
In comparison, forest fires in Western Europe, where forests are properly managed are extremely rare.
Third, properly designed firebreaks do not even remotely resemble a patch work of vineyards as Mr. Smith suggests. Their standards include firefighting equipment access roads at prescribed intervals along with accesses to them. The USDA Natural Resources Conservation Service Practice Code 394 and the Fuel Break Guidelines of the Tasmania Fire Service Bushfire Policy are good information starting points. And let's not ignore the visual blight of such deforested patchwork.
The scientific community established that 84 percent of all wildfires are caused by human activity. Vineyards and wineries with their tasting rooms and events in the hillsides invite such activity. The cigarette butts along Soda Canyon Road are enough to convince any doubter how inappropriately dangerous such development is. Mr. Smith failed to include this parameter in his science.
Fourth, Mr. Smith argues that the absence of pesticides in the Napa River (if true) is scientific proof that pesticide use at hillside vineyards is harmless. Yet, scientific inquiry would ask the question that if they are being used, how do they simply disappear? The truth is that they end up in the water table, and from there, in all of us.
Mr. Smithers is being castigated by Mr. Smith as irresponsible -- even demanding that he issue an apology to the wine industry -- for suggesting that the use of pesticides such as Roundup (containing Glyphosate) is responsible for Napa Valley's highest cancer incidents for children and second in adults in California.
I hope Mr. Smith did not hold Bayer AG (Monsanto's parent company) stock. Its price plummeted more that 10 percent in August 2018 following the California Superior Court in San Francisco County $289 million award to a former school groundskeeper for developing non-Hodgkin's lymphoma due to his exposure to Roundup.
If Mr. Smith is waiting for chemical cause and effect proof to the link of Glyphosates to cancer, he ought to consider that such chemical link of the use of tobacco to cancer has yet to be established. The link is a statistical one, enough for an eventual call to action -- but only after millions died.
Sadly, proving a chemical link between the use of Roundup and cancer enough to satisfy Mr. Smith will be just as impossible. While we are waiting for the eventual statistical evidence, hundreds of Napa Valley children - millions around the globe - will have their lives shortened. This is what is irresponsible.
But the noose is closing ever tighter around Bayer AG's neck since 2005. The European Union has rescinded its usual 15-year extension to the use of Glyphosates and limited it to three. France has pledged its outright ban in three years, Germany and Italy are considering similar action.
But the Napa Valley remains hostage to the wine industry in spite of all the evidence. Shockingly, Napa is one of the few counties in the state that has no mandated pesticide-free zones around our schools. Shame on it.
