DIATOMEJE: KO BISTVO POSTANE OČEM VIDNO Ob vse hitrejšem tehnološkem razvoju človeške civilizacije, ki v nenehnem hlastanju za še večjo gospodarsko rastjo izčrpava naravne vire na našem edinstvenem planetu, postaja varstvo narave nepogrešljivo področje človekovega delovanja. Srečujemo ga vsepovsod in v najrazličnejših oblikah; številne od teh so le sprenevedanje, »okoljska odgovornost« na papirju ali na spletnih straneh, v resnici pa lov podjetij in velikih družb za prestižem, kjer okolje v vsakdanjem besednjaku pač ne sme manjkati — če je za tem še nekaj »ekoloških odpustkov« v zameno za tihe obremenitve okolja in izkoriščanje naravnih virov, smo lahko še zadovoljni. Pogosto tudi tega ni. Na drugi strani so redki zanesenjaški posamezniki in nekatere nevladne nepridobitne organizacije, za katere je varstvo narave postalo način življenja; takšni z zavidljivo majhnimi sredstvi opravijo ogromno delo in pogosto celo naloge, ki bi jih za davkoplačevalski denar morala opraviti država oz. organi v njeni sestavi. Največkrat ostanejo takšna dejanja pri »javnem sektorju« nerazumljena in finančno še naprej podhranjena, nezanimiva za medije, njihov pomen in vpliv v javnosti pa ravno zato težko preverljiv. Prav dokazovanje in merljivost vpliva pa je za presojevalce projektov, posebej evropskih, ključnega pomena. Koliko ljudi je obiskalo razstavo in kakšna je bila sestava te javnosti, v katerih medijih so poročali o dogodku, ali je prav ta dogodek (in ne morda katera druga dejavnost ali kampanja nacionalnega ali evropskega obsega) vplival na dvig zavedanja javnosti o pomenu varstva narave in posebej segmenta, s katerim se dogodek ukvarja, koliko odstotkov se je to zavedanje dvignilo in kako se to kaže v ravnanju ciljnih skupin ali izboljšanju ohranitvenega stanja nekaterih vrst … Pred temi in takimi vprašanji obupa marsikateri goreč zagovornik varstva narave — in »popusti posvetno rabo …« ali pa pregori. Zakaj nekateri vendarle ne obupamo? Kateri sodoben energent nas poganja, da še naprej, čeprav pogosto brez upanja na obzorju, spreminjamo navidez neuresničljive zamisli v resničnost? Odgovor je en sam: poganjajo nas fantastične zgodbe, kakršna je ta o drobcenih kremenastih algah, ki so postale velike — dovolj velike, da so obsedle domišljijo ljudi, ki po svetu hodijo z odprtimi očmi in odprtim srcem. Toda alge niso prerasle svojih naravnih okvirov kar tako; potreben je bil srečen splet prijateljstva in razumevanja, izvirnih zamisli, ki so se kot snežna krogla bogatile, ko so preskakovale med udeleženci tega ustvarjalnega procesa. Zgodba o diatomejah je zgodba, spočeta iz iskrice, ki se utrne dolgoletnim stanovskim in pevskim prijateljem v sproščenem klepetu ob pivu: Kaj je vendar narobe s temi diatomejami, da jih ljudje ne prepoznajo?

DIATOMS: WHEN ESSENTIAL BECOMES VISIBLE TO THE EYE Along with the even faster technological development of the human civilisation, continuously snapping for economic growth, that way depleting natural resources on our unique planet, nature conservation is becoming indispensable field of human activity. We are encountering it everywhere and in various forms; many of them are merely hypocrisy, an “environmental responsibility” of big companies only on paper or on websites, in reality it is only catching for prestige. Of course, the environment became “a must” in everyday vocabulary — if there are some “ecological indulgences” behind in exchange for silent environmental burdens and exploitation of natural resources, we are usually satisfied. Very often, we lack also these. On the other hand, there are rare enthusiastic individuals and some nongovernmental and non–profit organizations for which nature conservation has become a way of life; with an enviable small funds, they undergo tremendous work and often even do the tasks which should be done by the state or government bodies for taxpayers’ money. Most of these actions remain misunderstood and continuously financially underfed by “public sector”, not interesting enough for media; therefore their importance and impact to the public is very difficult to be verified. And yet providing of evidences and quantification of impacts to the evaluators of projects, especially European ones, is of outmost importance. How many people did attend the exhibition and what was the structure of this public, by which media the event was covered, did this very event (and not maybe some other national or European activity or campaign) influence to the rising of public awareness about the importance of nature conservation, especially of the topic this event is dealing with, what was the percentage of rising of the awareness and how this is expressed in treatment of the target groups or in improvement of conservation status of some species … Before these and similar questions also a passionate defender of nature conservation loses his heart — and he eventually leave his work or even burns out. Why some of us do not despair? What is the secret energy source keeping us moving forward, even if there is often not a glimmer of hope? How we succeed to change apparently unrealistic ideas to reality? There is only one answer: we are inspired by fantastic stories like this one about tiny diatoms becoming big enough to obsess the imagination of those people, who are walking around with their eyes as well as their heart wide open. However, the algae haven’t overgrow their natural framework just like that; a lucky web of friendship and understanding was necessary, however, also original ideas enriching themselves like a snowball while jumping between participants of this creative process. The story of diatoms is a story, conceived from the sparkle, when “birds of a feather” that flock and sing together, for many years hang out in the evenings having a beer and chatting. What on earth is wrong with the diatoms that people don’t recognize them? Producing 40 % of oxygen and representing a quarter of the entire biomass, they are indispensable for the life on this planet! They are essential for the primary production (producing of the organic substances in the process of photosynthesis) in water ecosystems and this, again, is essential for all next levels in the food web stretching right to the “crown of creation”, to the human. Moreover, the richness of diatom forms and beauty of skeleton patterns are beyond the human imagination. And yet, when talking about nature conservation, our first thought is a panda or a whale, among European animals maybe a bear, wolf, otter, an eagle or horned owl — in a word, predator animals, that are on the top of food web. Why they are closer to us? Because we can easily see them with the naked 11
