Sje\u0107am se devedesetih i tr\u010dkaranja gore-dolje po Botani\u010dkom vrtu u Zagrebu. Malena ja bila je potpuno o\u010darana dubokim zelenilom u sredi\u0161tu sivih zidova glavnoga grada.<\/p>\n\n\n\n

I dok sam stajala na livadi i razmi\u0161ljala koji kutak Vrta istra\u017eiti, pa\u017enju su mi zaokupile stotine i stotine masla\u010daka. Bio je prekrasan, sun\u010dan dan, a vjetar je malenim bijelim padobranima podario mo\u0107 letenja. Lebdjeli su pored mene, \u010dine\u0107i taj prizor veoma sli\u010dnim prvom snje\u017enom danu.<\/p>\n\n\n\n

Cvat masla\u010dka sastoji se od brojnih malih \u017eutih jezi\u010dastih cvjetova. S vremenom do izra\u017eaja dolazi papus \u2013 \u201epadobrani\u201c koji poma\u017eu u rasprostiranju sjemena. Te bijele dla\u010dice omogu\u0107avaju da sjeme ne samo ostane u zraku, ve\u0107 i da se uzdigne u ve\u0107e visine.<\/p>\n\n\n\n

Naime, oblikovane su na na\u010din koji omogu\u0107ava zraku da, prolaze\u0107i kroz filamente, ide prema gore. Zrak pritom formira vrtlog, koji iznad papusa stvara polje niskog tlaka te se papus uzdi\u017ee prema ni\u017eem tlaku. Duljina, broj i razmje\u0161taj filamenata u papusu, sve je savr\u0161eno raspore\u0111eno sukladno zakonima fizike.<\/p>\n\n\n\n

Jedna biljka masla\u010dka proizvodi od 3000 do 8000 sjemenki u jednoj sezoni, a sjemenke mogu zadr\u017eati mogu\u0107nost klijanja do 600 godina. Zamislite samo \u2013 to je tek jedna biljka. Na jednome polju mogu biti desetci ili stotine masla\u010daka, od kojih svaki osigurava postojanje svoje vrste jo\u0161 idu\u0107ih nekoliko stotina godina.<\/p>\n\n\n\n

Mnoge druge vrste tako\u0111er su prona\u0161le razli\u010dite na\u010dine odr\u017eavanja.<\/p>\n\n\n\n

Jesu li ljudi ta jedna vrsta koja ne razmi\u0161lja o novim generacijama? Te\u017eimo biti veliki, napredni, uspje\u0161ni, tehnolo\u0161ki nadmo\u0107ni, ali \u010dini mi se da zaboravljamo da bilo kakav oblik razvoja treba biti odr\u017eiv. Kad bismo to ostvarili, tek to bi bio pravi uspjeh.<\/p>\n\n\n\n

Brojni ljudi osobni razvoj i osobni uspjeh poimaju krajnjim \u017eivotnim ciljem. U ovom bjesomu\u010dnom \u017eivotnom natjecanju zaboravili smo sagledati \u0161iru sliku, misliti unaprijed, \u010dak i misliti na druge - uklju\u010duju\u0107i i vlastitu djecu.<\/p>\n\n\n\n

Mnogi od nas \u017eele osnovati obitelj, ali sada \u010dinimo tako malo za bolju budu\u0107nost svoje djece. Ne znamo ho\u0107e li budu\u0107e generacije vidjeti sve prirodne ljepote kojima mi danas svjedo\u010dimo. Ono \u0161to znamo jest da nam djeca ne\u0107e vidjeti mnoga \u010duda u kojima smo mi u\u017eivali kao djeca.<\/p>\n\n\n\n

Mnogo se toga promijenilo od mog djetinjstva. Mnoge prizore tako bih rado ponovno gledala, ali znam da to nije mogu\u0107e.<\/p>\n\n\n\n

A masla\u010dak, on nastoji osigurati postojanje svoje vrste idu\u0107ih 600 godina.<\/p>\n\n\n\n

Ovdje i u mnogo drugih primjera iz prirode mo\u017eemo prona\u0107i brojne ideje, lekcije i pouke. \u010cak i na mjestima na kojima to nikada ne bismo o\u010dekivali.<\/p>\n\n\n\n

I remember the 90\u2019s, and running back and forth through the Zagreb Botanical Garden. Little me was fascinated by the greenery in the middle of the gray walls of the capital.
