Los peligros de la ignorancia científica

Hasta ahora he considerado a La Vanguardia como un periódico serio. Sin embargo, en los últimos tiempos están dando cobijo a una serie de personajes que propagan sus ideas pseudocientíficas en sus venerable páginas.

Lo último que me ha llegado, se publicó el pasado 30 de mayo. Una entrevista a un ¿divulgador? y ¿agricultor ecológico? que afirma «Estamos comiendo petróleo«.

Claro, leí el titular y pensé que la entrevista se la estaban haciendo a un microorganismo extremófilo, de esos raros que son capaces de comerse las porquerías que dejó el maldito Prestige (sí, ese; se acuerdan, el de «los hilitos» que dijo un tal M. Rajoy Brey) en nuestras costas gallegas; y que esa afirmación estaba dirigida a sus congérenes, y otras especies relacionadas, devoradoras de hidrocarburos.

Pero no es un bichito de esos que le gustan a mis amigos los (micro)biólogos. Al menos por la foto de la entrevista, no es un microorganismo; sino que es, aparentemente, un individuo de nuestra especie (homo ¿sapiens?). Bueno, pienso «ha sido una exageración del periodista que ha querido sacar un titular de una frase inocua del entrevistado«.

¡¡¡Pero no!!! Este tal señor agricultor ¿ecológico? y ¿divulgador? lo dice  en la entrevista. A continuación reproduzco literalmente la pregunta y la respuesta:

P.: Incluso hay productos, según explica usted, que… ¡llevan petróleo!
R.: Efectivamente. De hecho, algo más del 90% de los productos de síntesis química (insecticidas, herbicidas, todo lo que no son productos agroecológicos) provienen todos del petróleo. Sin saberlo, estamos comiendo petróleo. Evidentemente, te lo comes tan disgregado que no te lo parece, pero lo estás haciendo.

Como se ve, no hay lugar para la duda.

Y esa respuesta demuestra que este individuo es un profundo ignorante científico. Y que conste que lo de ignorante no es insulto, sino que es el significado del diccionario de la RAE para «el que no tiene noticia de algo«.

Y este señor agricultor ¿ecológico? tiene una profunda ignorancia de química. No voy a darle ninguna lección de química (que se compre un libro para aprender), sólo decirle que la química es la ciencia de la transformación de la materia y que cuando A se transforma en B; A y B son dos sustancias químicas distintas (como si fuesen dos letras distintas del alfabeto) y, por consiguiente, sus propiedades (químicas, físicas, biológicas, tecnológicas) son también distintas.

Le voy a poner un ejemplo sencillo, que usted, señor agricultor ¿ecológico? puede entender.

El hidrógeno es un gas, explosivo por más señas. Si respiramos hidrógeno, morimos, al menos asfixiados, aunque podríamos tener una muerte aún más cruenta.

El oxígeno es también un gas. Es esencial para nuestra vida; pero, eso sí, mezclado con otro gas (el nitrógeno) en una proporción aproximada de 4 a 1 (exactamente 78 a 21) formando el aire (el 1% restante es mezcla de otros gases). Aunque el oxígeno es fundamental para nuestra existencia, en estado puro es un veneno potente para el ser humano y si lo ingerimos puro y en cantidad, tendríamos una muerte segura, y además espectacular (más o menos como una falla valenciana).

Pero, ¿qué ocurre si mezclamos estos dos gases (hidrógeno y oxígeno) tan peligrosos? ¡Se forma agua! Un líquido, no tóxico y esencial para la vida. Una reacción química hace que dos gases extremadamente peligrosos se combinen dando lugar a un ¡líquido esencial para la vida!

Espero que este ejemplo aporte alguna luz a su ignorancia química y se dé cuenta de que una vez que un derivado del petróleo se transforma químicamente, las propiedades de lo que se obtiene no tiene nada que ver con el material de partida y, mucho menos con el petróleo que  antes de estos procesos se somete a una destilación para separar componentes.

Para su información, los compuestos químicos más sencillos que se encuentran en el petróleo son el metano y el etileno. El metano da poco juego en la preparación de sustancias químicas sintéticas; aunque sí para proporcionarnos energía, que este señor agricultor ¿ecológico? usará; pues no creo que se caliente con la madera de sus bosques o no encienda ni una bombilla en su casa.

El etileno es un material de partida importante para la industria química de la que el señor agricultor ¿ecológico? se beneficia; o ¿es que va desnudo por la vida o no usa un simple bolígrafo para escribir o un ordenador o un teléfono móvil? cuando enferma ¿qué toma?

Las interrogantes en agricultor ¿ecológico? no son un error de mi teclado. ¡No! Son intencionadas. No voy a entrar con discutir a los defensores de una cierta manera de cultivar los campos (para eso están Mulet o JAL); pero sí me molesta que se falsee la terminología. Agricultura ecológica es un oxímoron, pues desde el momento en que un campo se cultiva (es decir, se hace agricultura) se deja de hacer ecologismo al estar manipulado por la mano del hombre. Por lo tanto, la agricultura ecológica no existe.

Este hombre tiene una propuesta curiosa. Propone que todos debemos plantar un huerto (por ejemplo, de lechugas; aunque es más ambicioso y propone variedad de cultivo) en nuestros balcones y terrazas. Si  estáis interesado en esta ideas (no voy a entrar a valorarla para que no me dé un ataque de risa) u os preguntáis como se puede alimentar una familia con esta ¿abundante? cosecha, recomiendo leer la blanda entrevista.

Yo voy a seguir con lo mío: la QUÍMICA (¡con mayúsculas!) y por desgracia con la ignorancia del señor agricultor ¿ecológico?

Propone plantar huertos ecológicos en los balcones de las viviendas para de esta manera «no tener que comer petróleo». Teniendo en cuenta el escaso conocimiento químico que este señor agricultor ¿ecológico? ha demostrado, no esperaba de él un mínimo conocimiento bioquímico.

Le digo a este señor agricultor ¿ecológico? que cuando coma la lechuga de su huerto (perdón, balcón) también está comiendo petróleo. Si este señor agricultor ¿ecológico? está leyendo este post se le quedarán los ojos como platos. «¿Comer petróleo? ¡¡¡Si todo es super-mega-ultra-ecológico!!!«, me responderá.

Si, señor agricultor ¿ecológico?, según su conocimiento de química, usted está comiendo petróleo cuando se come su lechuga. «¿Por qué?» Me preguntará el señor agricultor ¿ecológico?. La respuesta es sencilla. Usted se come la lechuga; principalmente está comiendo carbohidratos (y otras sustancias químicas) que se han sintetizado (sé que la palabra le horroriza, pero es verdad) por las células de la planta. Y usted me contestará «que todo es muy natural, muy eco y muy bio» Yo le contestaré «¿Y sabe usted de dónde procede el carbono de los carbohidratos de la lechuga que se está comiendo?» Teniendo en cuenta sus conocimientos de química, su respuesta será «No» y en ese momento yo le contestaré (con una media sonrisa) «Del CO2, también conocido como dióxido de carbono o anhídrido carbónico» Y este señor agricultor ¿ecológico? se echará a temblar, pues le he nombrado a una de sus bestias negras, el CO2. Y además, le digo que ese CO2 procede de la combustión de derivados de hidrocarburos en automóviles o centrales térmicas; es decir, del petróleo.

Por lo tanto, sintiéndolo mucho, señor agricultor ¿ecológico?; usted también come petróleo de su huerto (perdón, balcón). Sólo tiene una alternativa, no comer. Claro, así seguro que se muere pronto (eso sí, sin estar químicamente contaminado); o más fácil, no vuelva a exponer su ignorancia científica en los medios de comunicación.

Nota tras el post químico. Aunque he preferido centrarme en los aspectos químicos de la entrevista, ésta no tiene desperdicio. Como cuando dice que hay que cortar el cesped cuando la Luna esté en la constelación de Gémini (triste es que un periódico serio publique esto, que parece una broma) o como le gusta observar la actividad sexual de insectos en su huerto (perdón, balcón) o que, como ocurre con mucho iluminados, él conoce la planta que cura el cáncer (¿todos? ¿los más 300 tipos de enfermedad que se clasifican con el epígrafe cáncer?).

  1. Well done, the kind of post that makes you slow down and actually read instead of skimming for keywords, and a look at bondedstability kept me reading carefully too, that is a sign of writing that has been crafted rather than churned out for an algorithm to see today and tomorrow.

  2. This stands out compared to similar posts I have read recently, less noise and more substance, and a look at actioncreatesforwardpath kept that gap going, you can really feel the difference between content made by someone who cares versus content made to fill a publishing schedule for an algorithm trying to keep growing somehow.

  3. Worth saying that the writing carries a particular kind of authority without making any explicit claims to it, and a stop at collaborativepowergroup extended that earned authority feeling, sites that demonstrate expertise through the quality of their explanations rather than by stating credentials are sites I trust most and this site has it.

  4. Reading this triggered a small but real correction in something I had assumed, and a stop at momentumplanning extended that corrective effect, content that updates my beliefs through evidence rather than rhetoric is content with intellectual integrity and this site has earned that label consistently across the pieces I have read so far today.

  5. A clear case of writing that does not try to do too much in one post, and a look at businessbondcircle maintained the same scoped discipline, posts that try to cover too much end up covering nothing well and this site has clearly chosen scope discipline as a core editorial principle which shows up clearly in what I read.

  6. More original than the recycled takes I keep finding on the topic elsewhere, and a quick look at claritysystems confirmed it, the kind of site that has its own voice rather than echoing whatever is trending which makes it stand out as a refreshing change from the usual rotation of generic content I see daily.

  7. Approaching this site through a casual link click and being surprised by what I found, and a look at strongalliancelink extended the surprise, the rare experience of stumbling into excellent independent content rather than predictable mediocrity is one of the actual remaining pleasures of casual web browsing and this site provided it cleanly.

  8. Appreciated the way each section connected smoothly to the next without abrupt jumps, and a stop at actionmovesstrategy kept that flow going nicely, transitions are something most blog writers ignore but the difference is huge for the reader who is trying to follow a sustained line of thought today across many different topics.

  9. Picked this up between two other things I was doing and got drawn in completely, and after growtharchitect my original tasks were completely forgotten for a while, content that derails a workflow in a positive way by being more interesting than what you were already doing is rare and worth recognising clearly.

  10. Now feeling confident enough in this site to use it as a reference point for evaluating others on the same topic, and a look at momentumactivation continued the comparison friendly quality, sites that serve as quality benchmarks for their topic are precious and this one has clearly become a benchmark for me on this particular subject area.

  11. Worth flagging this post as worth a careful read rather than a casual skim, and a stop at businessunitynetwork earned the same careful approach, the few sites that warrant slower reading are sites I now treat differently from the daily content stream and this one has clearly moved into that elevated treatment category.

  12. A piece that demonstrated competence without performing it, and a look at progressflowswithclarity maintained the same self assured but unshowy register, the gap between competence and performance of competence is one I track and this site has clearly chosen to demonstrate rather than perform which I find much more persuasive as a reader.

  13. Walked away in a slightly better mood than when I started reading, that says something about the writing, and a stop at actioncreatespathways kept that going, content that leaves you feeling more capable rather than overwhelmed is the kind I keep coming back to again and again over the years and across many topics.

  14. Halfway through I knew I would finish the post, and a stop at forwardpathway also held me through to the end, content that signals its quality early and then sustains it is content with real internal consistency and this site has clearly figured out how to maintain quality from opening sentence through to closing thought.

  15. Appreciated how the post felt complete without overstaying its welcome, and a stop at claritymotionlab confirmed that economical approach runs across the site, knowing when to stop is a skill many writers never develop but here the discipline is obvious and welcome from the perspective of a busy reader trying to learn things efficiently.

  16. Probably the kind of site that should be more widely read than it appears to be, and a look at signalshapesprogress reinforced that quiet wish, the gap between a sites quality and its apparent reach is sometimes large and that gap exists for this site in a way that makes me want to mention it more.

  17. Comfortable reading experience throughout, no jarring tone shifts and no awkward formatting, and a look at claritycreatesprogress kept that smooth feel going, the kind of editorial polish that goes unnoticed when present but glaring when absent is something this site has clearly invested in across the broader content as well which deserves recognition.

  18. Bookmark added with a small mental note that this is a site to keep, and a look at truebondnetwork reinforced the keep status, the verb keep rather than visit captures something about how I think about this kind of site and it is a higher tier of relationship than I have with most places online today.

  19. The post made the topic feel approachable without making it feel trivial, that is a fine balance, and a stop at bondedcollective maintained the same balance, finding the middle ground between welcoming and serious is genuinely difficult and the writers here have clearly figured out how to consistently hit it well across many different posts.

  20. Felt the post had been written without looking over its shoulder, and a look at signalcreatesdirectionalflow continued that confident posture, content written for its own sake rather than against imagined critics has a different quality and this site reads as written from a place of confidence rather than defensive justification of every claim.

  21. Appreciate the thoughtful approach, the writer clearly took time to make this readable for someone who is not already an expert, and a look at claritylane kept that going nicely, easy on the eyes and easy on the brain which is always a winning combination when reading on a busy day.

  22. Solid endorsement from me, the writing earns it, and a look at ideaexecutionhub continues to earn it across the broader site too, the kind of operation that maintains quality across many pages rather than just one viral post is a sign of serious commitment and that is what I see here clearly across what I read.

  23. Worth flagging this post as worth a careful read rather than a casual skim, and a stop at forwardpathconstructed earned the same careful approach, the few sites that warrant slower reading are sites I now treat differently from the daily content stream and this one has clearly moved into that elevated treatment category.

  24. Well structured and easy to read, that combination is rarer than people think, and a stop at directionanchorsmotion confirmed the same standard runs across the rest of the site, definitely the kind of place I will be coming back to when this topic comes up in conversation later again over the weeks ahead.

  25. Now thinking the topic is more interesting than I had given it credit for, and a stop at growthlogic continued that elevated interest, content that revives my curiosity about subjects I had set aside is doing genuine work in the structure of my interests and this site is providing that revivifying effect today actually.

  26. Quietly the post solved something I had been turning over without quite knowing how to phrase the question, and a look at trustedrelationshipnet extended that quiet solving, content that addresses unformulated needs is content with reader insight and this site has demonstrated that insight at a high rate across the pieces I have read recently.

  27. Reading this on the train into work was a better use of the commute than my usual choices, and a stop at progressengineered extended that commute reading well, content that improves transit time rather than just filling it is content with practical benefit and this site has earned its place in my morning commute reading rotation.

  28. Closed the tab and immediately reopened it ten minutes later because I wanted to reread a part, and a stop at visionarybondcircle drew the same return, content that pulls you back after closing it is doing something well beyond the average and worth marking as exceptional in my mental catalogue of reliable sites.

  29. Once I had read three posts the editorial pattern was clear, and a look at ideaconverter confirmed the pattern from a fourth angle, sites where the underlying approach reveals itself through accumulated reading rather than being announced are sites with real depth and this one has that quality clearly visible across multiple pieces consistently.

  30. Now thinking about how to apply some of this to a project I have been planning, and a look at futuregrowthalliance added more material for the planning, content that connects to my actual creative work rather than just being interesting in the abstract is the kind that earns priority placement in my reading rotation consistently going forward.

  31. Now realising the topic deserved better treatment than it has been getting elsewhere, and a look at ideasgainalignment extended that broader recognition, content that exposes the gap between actual quality and average quality elsewhere is doing the quiet work of raising standards and this site is contributing to that elevation in its own corner.

  32. Started smiling at one paragraph because the writing was just nice, and a look at strategyactivation produced a couple more such moments, prose that produces small spontaneous reactions in the reader is doing more than just transferring information and the writers here are clearly hitting that level fairly consistently throughout pieces.

  33. Reading this in the gap between work projects was a small but meaningful break, and a stop at focuscreatesdirection extended that gentle reset, content that provides genuine refreshment rather than just distraction during work breaks is content with a particular kind of utility and this site fits that role for me reliably during work days.

  34. Decided to write a short note to the author if there is contact info anywhere, and a stop at progressmoveswithdesign extended that intention, the urge to thank the writer directly is a strong signal of content quality and this site has triggered that urge in me today which is a fairly rare event for my reading.

  35. Beats most of the alternatives on the topic by a noticeable margin, and a look at directionalplanninglab did not change that at all, this is one of the better corners of the open internet for this kind of content and I am glad I clicked through rather than skipping past quickly like I usually do.

  36. Reading this felt easy in the best way, no friction and no confusion at any point, and a stop at growthoriented carried that same comfort across more pages, the kind of editorial flow that lets you absorb information without fighting the format which is increasingly hard to find on the open web today across topics.

  37. Looking through the archives suggests this site has been doing this for a while at this level, and a look at businesssynergyhub confirmed the long term consistency, sites that have maintained quality across years rather than just a recent stretch are sites with serious editorial discipline and this one has clearly been at it for a while.

  38. Definitely a recommend from me, anyone curious about the topic should check this out, and a look at bondedendurance adds even more reason for that, the depth and quality combine to make this site one I will be pointing people toward whenever similar conversations come up over the months ahead at work or socially.

  39. Bookmark earned, calendar reminder set, share queued, all from one good post, and a look at capitalbondcircle did the same, when a single reading session triggers multiple downstream actions you know the content has actually moved me beyond the page and this site is moving me at that higher level reliably.

  40. Came in confused about the topic and left with a much firmer grasp on it, and after growthmoveswithpurpose I felt I could explain this to someone else without hesitation, that is the gold standard for any educational content and most sites simply fail to reach it ever which is unfortunate but true.

  41. Highly recommend to anyone looking for a sensible take on this topic without the usual marketing nonsense, and a look at clarityanchorsdirection kept that grounded approach going, sites that stay focused on serving readers rather than monetising every click are rare and this is clearly one of those rare ones I really appreciate finding.

  42. Solid quality, the kind of work that holds up to a careful read rather than a quick skim, and a quick look at claritystarter kept that standard going strong, content that rewards attention rather than punishing it is something I appreciate more and more these days online across nearly every topic I follow.

  43. Thanks for the practical examples scattered through the post rather than abstract theory only, and a look at momentumtrack continued that grounded style, abstract points are easier to remember when paired with concrete situations and the writers here clearly understand how readers actually retain information from blog content reading sessions.

  44. Reading this on a phone at a coffee shop and finding it perfectly suited to that context, and a stop at ideatoimpact continued the comfortable mobile experience, content that works across reading conditions without compromising on substance is increasingly important and this site has clearly thought about the whole reader experience here.

  45. Worth bookmarking and sharing with anyone interested in the topic, that is my honest take, and a stop at claritydrivesmomentum reinforces that, the kind of generous resource that makes the open web feel worth defending against the constant pressure to retreat into walled gardens and curated feeds today everywhere I look across all my devices.

  46. Now feeling confident enough in this site to use it as a reference point for evaluating others on the same topic, and a look at trustedpartnerhub continued the comparison friendly quality, sites that serve as quality benchmarks for their topic are precious and this one has clearly become a benchmark for me on this particular subject area.

  47. More original than the recycled takes I keep finding on the topic elsewhere, and a quick look at directionalshiftlab confirmed it, the kind of site that has its own voice rather than echoing whatever is trending which makes it stand out as a refreshing change from the usual rotation of generic content I see daily.

  48. A piece that built up gradually rather than front loading its main points, and a look at trustedvaluepartners maintained the same gradual structure, content that trusts the reader to reach conclusions through accumulating reasoning is more persuasive than content that announces conclusions and then defends them and this site uses the persuasive approach.

  49. Liked the post enough to read it twice and the second read found new things, and a stop at progressdriver similarly rewarded the second look, content with hidden depths that only reveal themselves on careful rereading is the rare kind that earns lasting respect rather than fleeting first impressions only briefly held.

  50. My usual pattern is to skim and bounce but this site has reset that pattern temporarily, and a stop at directionpowersmovement maintained the slower reading mode, content that changes how I read is content with structural influence and this site has clearly nudged my reading behaviour toward something better at least for the duration of these visits.
