Cercetarea, realizat\u0103 de o echip\u0103 coordonat\u0103 de speciali\u0219ti de la Universitatea Oxford, arat\u0103 c\u0103, dac\u0103 \u00eentreaga produc\u021bie de ou\u0103 din Marea Britanie ar fi realizat\u0103 exclusiv \u00een sistem ecologic \u0219i cu g\u0103ini crescute \u00een aer liber, emisiile de gaze cu efect de ser\u0103 ar ajunge la echivalentul a 2.316.000 de tone de CO\u2082. \u00cen schimb, un sistem bazat integral pe g\u0103ini crescute \u00een cu\u0219ti ar genera aproximativ 1.184.000 de tone de CO\u2082, aproape la jum\u0103tate.<\/p>\n

Potrivit cercet\u0103torilor, diferen\u021ba este explicat\u0103 prin faptul c\u0103 g\u0103inile crescute \u00een sistem ecologic \u0219i \u00een aer liber sunt mai pu\u021bin productive, fiind nevoie de un num\u0103r mai mare de p\u0103s\u0103ri pentru a produce aceea\u0219i cantitate de ou\u0103.<\/p>\n

Pe l\u00e2ng\u0103 emisiile de carbon, sistemele ecologice au ob\u021binut rezultate mai slabe \u0219i \u00een ceea ce prive\u0219te utilizarea terenurilor, acidificarea mediului \u0219i eutrofizarea apelor. De asemenea, rata mortalit\u0103\u021bii g\u0103inilor a fost mai ridicat\u0103 \u00een fermele ecologice analizate.<\/p>\n

Autorii studiului subliniaz\u0103 \u00eens\u0103 c\u0103 cercetarea are mai multe limit\u0103ri. Analiza s-a bazat pe date colectate \u00een perioada 2009-2010, care nu reflect\u0103 evolu\u021biile din ultimii ani ale industriei avicole. Totodat\u0103, studiul nu a inclus alte aspecte importante de mediu, precum utilizarea pesticidelor sau impactul asupra biodiversit\u0103\u021bii.<\/p>\n

Dr. Harriet Bartlett, cercet\u0103tor la Universitatea Oxford \u0219i unul dintre autorii studiului, afirm\u0103 c\u0103 produc\u021bia de ou\u0103 este adesea ignorat\u0103 \u00een dezbaterile despre sustenabilitate.<\/p>\n

\u201eCarnea \u0219i produsele lactate primesc mult mai mult\u0103 aten\u021bie atunci c\u00e2nd discut\u0103m despre impactul asupra mediului, \u00een timp ce produc\u021bia de ou\u0103 a fost cercetat\u0103 mult mai pu\u021bin\u201d, a explicat aceasta.<\/p>\n

Potrivit cercet\u0103toarei, rezultatele eviden\u021biaz\u0103 un compromis dificil \u00eentre protec\u021bia mediului \u0219i bun\u0103starea animalelor.<\/p>\n

\u201eAm constatat un compromis important. Tipurile de ferme considerate, \u00een general, mai bune pentru bun\u0103starea animalelor, precum cele ecologice \u0219i cele cu g\u0103ini crescute \u00een aer liber, pot necesita mai multe p\u0103s\u0103ri pentru a produce aceea\u0219i cantitate de ou\u0103, deoarece sunt mai pu\u021bin eficiente \u0219i pot avea un impact mai mare asupra mediului\u201d, a declarat Harriet Bartlett.<\/p>\n

\u00cen cadrul cercet\u0103rii, oamenii de \u0219tiin\u021b\u0103 au analizat date din ferme avicole britanice pentru a calcula impactul asupra mediului \u2013 inclusiv emisiile de gaze cu efect de ser\u0103, utilizarea terenurilor \u0219i diferite forme de poluare \u2013 precum \u0219i indicatori privind bun\u0103starea animalelor, cum ar fi mortalitatea \u0219i num\u0103rul de g\u0103ini necesare pentru producerea unui anumit num\u0103r de ou\u0103.<\/p>\n
