Paradoxul ouălor bio: un nou studiu arată că produc mai multe emisii de carbon decât ouăle din fermele intensive

A new study reveals that organic eggs may produce more carbon emissions than those from intensive farming, challenging sustainability perceptions. Researchers from Oxford University found that if all UK eggs were produced organically, emissions could reach 2.3 million tons of CO₂, compared to 1.2 million tons from caged hens. The lower productivity of free-range hens necessitates more birds for the same egg output, leading to higher environmental impacts. The study also highlights higher mortality rates in organic farms and calls for more attention to egg production in sustainability discussions.
