Na svetu postoji 20.000 razli\u010ditih vrsta p\u010dela. Najve\u0107i broj vrsta \u017eivi u kolonijama \u2013 p\u010delinjim zajednicama koje uklju\u010duju: maticu, p\u010dele radilice i trutove. Jedna p\u010delinja zajednica ima samo jednu maticu, a iako su i matica i p\u010dele radilice \u017eenke, samo matica mo\u017ee da se razmno\u017eava. P\u010dele radilice \u010diste ko\u0161nicu, sakupljaju polen i nektar kako bi hranili koloniju i vode ra\u010duna o potomcima.<\/span><\/p>\n

\u010cesto ka\u017eemo \u201evredan kao p\u010dela\u201c. O tome koliko su p\u010dele zaista vredne govori podatak da tokom jednog dana jedna p\u010dela obi\u0111e i opra\u0161i vi\u0161e od 1000 cvetova! A koliko su ovi ljupki insekti zaista va\u017eni za prirodu i ljude?<\/span><\/p>\n

Bez p\u010dela nema hrane!<\/b><\/span><\/h2>\n

P\u010dele su sastavni deo ekosistema planete Zemlje milionima godina. Vredno opra\u0161uju biljke i proizvode slatki, lekoviti, zlatni sirup koji nazivamo medom. Ovi lete\u0107i insekti opra\u0161uju vi\u0161e od 80% biljaka koje koristimo u ishrani i <\/span>od p\u010dela zavisi svaki tre\u0107i zalogaj hrane koju jedemo<\/b>. P\u010delama mo\u017eemo da zahvalimo na nekim na\u0161im najomiljenijim namirnicama poput jabuka, kajsija, breskvi, tre\u0161anja, kru\u0161aka, jagoda, mandarina, lubenica, kivija, brusnice, borovnice, gro\u017e\u0111a, oraha, badema, krastavca, paradajza i mnogih drugih.\u00a0<\/span><\/p>\n

P\u010dele opra\u0161uju i biljke koje se koriste u ishrani stoke poput deteline i lucerke, pa imaju <\/span>zna\u010dajnu ulogu u proizvodnji mesa i mleka<\/b>. Na kraju, p\u010dele <\/span>proizvode med<\/b> \u2013 vrlo korisnu i lekovitu namirnicu, kao i p\u010delinji vosak koji se koristi jo\u0161 od doba starih Grka i Rimljana.\u00a0<\/span><\/p>\n

Bez p\u010dela bi mnoge biljne i \u017eivotinjske vrste nestale!<\/b><\/span><\/h2>\n

Svi znamo da su \u0161ume \u201cprirodna plu\u0107a Zemlje\u201d koja nam obezbe\u0111uju kiseonik, a bez p\u010dela koje opra\u0161uju mnoge vrste drve\u0107a, <\/span>\u0161ume ne bi mogle da se razvijaju i napreduju<\/b>, te bi vremenom nestale. P\u010dele opra\u0161uju i \u017ebunasto rastinje, cve\u0107e, travu, a kada ne bi bilo p\u010dela <\/span>nestali bi travnati ekositemi<\/b>. \u0160ume i livade su stani\u0161ta mnogih divljih vrsta – insekata, \u017eivotinja i ptica, a povla\u010denjem \u0161uma i livada bio bi <\/span>ugro\u017een opstanak vrsta<\/b> koji ih naseljavaju. One su najbolji pokazatelj bezbedne \u017eivotne sredine za \u010doveka jer mogu da \u017eive samo u zdravom i \u010distom okru\u017eenju.<\/span><\/p>\n

Uloga p\u010dela u industriji i ekonomskom razvoju!\u00a0\u00a0<\/b><\/span><\/h2>\n

Isprva, neki od nas mo\u017eda ne bi mogli da pove\u017eu p\u010dele i ekonomski razvoj. Ipak to je istina \u2013 p\u010dele su va\u017ene za mnoge grane industrije. Pre svega poljoprivredu \u2013 uzgajanje vo\u0107a, povr\u0107a, njihova uloga u sto\u010darstvu i ratarstvu. Na to se nadovezuje prehrambena industrija: proizvodnja sokova, alkoholnih i bezalkoholnih pi\u0107a, industrija mesa i mleka i dr. P\u010delinji vosak nezamenljiv je u industriji \u010delika, opti\u010dkoj industriji, proizvodnji voskovnih boja itd. Velike koli\u010dine voska koriste se i u industriji ko\u017ee, drveta i hartije. Industrija teksta tako\u0111e zavisi od p\u010dela – p\u010dele su va\u017ene u opra\u0161ivanju pamuka i lana koji su najrasprostranjeniji prirodni materijali za proizvodnju tekstila. Farmaceutska i kozmeti\u010dka industrija \u010desto koriste med i p\u010delinji vosak zbog njihovog blagotvornog dejstva za ljudski organizam.\u00a0<\/span><\/p>\n

ZBOG SVEGA OVOG MORAMO UPAMTITI: OD P\u010cELA ZAVISI OPSTANAK ZDRAVIH EKOSISTEMA, OPSTANAK LJUDI I \u017dIVOTINJA, OPSTANAK SVETA KOJI POZNAJEMO<\/b>!<\/span><\/span><\/h3>\n
