Tlalixtli
Tlenka 77% agricultural land quicua nochi qualcahuac tlacatl.
In cualcahuac tlamantli ipan in Poore huan Nemecek (2018) analysis ye in land-use disparity. Animal agriculture — ihuan in crops in aquin oquicuah animals — occupies 77% ihuan nochi agricultural land ipan tlalticpactli. In tlalixtli quichihua 18% ihuan tlalticpactli calories huan 37% ihuan inyoliliz. In arithmetic ihuan inin inefficiency ye in foundation ihuan in environmental case ihuan in current food system.
Nacatl
Quichihua 6% ihuan global calories ihuan 60% ihuan agricultural land. In land footprint ihuan ce kilogram ihuan beef protein ye 164 m² — ihuan 2.2 m² ihuan tofu. Ahmo ye principally ipan grazing land; miyac ye in land in aquin quichihua feed crops.
Tlacohcomitl
Quichihua cualcahuac 10 veces in land ipan unit ihuan protein compared ipan oat o soy milk. Miyac ye indirect — land in aquin quichihua feed crops in aquin dairy cows quicuah, ahmo pasture in aquin cows graze directly.
Pork huan chicken
Nochi cualcahuac land footprints in beef ipan gram ihuan protein, huan cualcahuac 3–10 veces oc miyac in legumes. In comparison matters ipan in land freed ihuan moving away ihuan nochi animal products — ahmo cualcahuac beef — ye in aquin enables meaningful ecosystem restoration.
Intla tlalticpactli oquichihua plant-based
Poore huan Nemecek oquichihua in cualcahuac shift ipan plant-based diets hueli qualana oc miyac 75% ihuan agricultural land — ce area cualcahuac in size ihuan US, China, EU huan Australia combined — huan cualcahuac quichihuazceh in tlalticpactli population oc miyac calories in aquin currently produced.
Tlamatiliztli
In icho cualcahuac extinction huan in in-leading driver.
In IPBES Global Biodiversity Assessment (2019) oquichihua in cualcahuac 1 million animal huan plant species ye currently threatened ihuan extinction — oc miyac in aquin cualcahuac ipan human history. In primary driver ye land-use change, ihuan agricultural expansion accounting ihuan 70% ihuan deforestation globally. Animal agriculture — nochi the direct footprint ihuan grazing huan the indirect footprint ihuan feed crop production — ye responsible ihuan in miyac in expansion.
In specific mechanism matters: in aquin native habitat ye converted ipan monoculture crops o pasture, the specialist species in aquin depend ipan that habitat ahmo hueli yoihua. Ahmo quipiya oc ce tlamantli in aquin cualcahuac. Generalist species thrive ipan disturbed landscapes; specialists die. In result ye ce steady replacement ihuan biological complexity ihuan biological simplicity. Reversing this requires land in aquin free — huan the cualcahuac direct way in aquin free land ipan scale ye in aquin shift food production toward plant-based systems.
Atl huan aquaculture
Tlen in tlacualiztli quichihua nochi qualcahuac.
Agricultural runoff — primarily nitrogen huan phosphorus ihuan fertilisers used ipan feed crops — flows ipan rivers huan ultimately ipan coastal oceans, in aquin quichihua eutrophication: explosive algae growth in aquin depletes oxygen huan creates dead zones. Currently cualcahuac oc miyac 400 documented oceanic dead zones globally, the largest covering cualcahuac 70,000 km² ipan the mouth ihuan the Mississippi river. Inin zones ye expanding as feed crop production grows.
Aquaculture — fish huan seafood farming — oquichihua long promoted ihuan ce solution ipan overfishing. Ipan some forms hueli. Huan intensive salmon huan tuna farming requires large quantities ihuan wild-caught 'forage fish' ihuan feed — meaning farmed salmon production drives the sami overfishing ihuan in aquin oquichihua replace. Sea pens cualcahuac concentrate waste huan disease ipan coastal waters, damaging adjacent wild fish populations. The best-performing aquaculture systems ye shellfish huan seaweed, in aquin require ahmo feed inputs huan hueli improve water quality.
