Peningkatan peternakan merupakan salah satu penyebab utama penggundulan hutan.4(UN FAO, 2006)
Sejak 1990-an sekitar 90% penggundulan hutan Amazon dikarenakan pembersihan lahan untuk tempat merumput sapi atau menanam makanan untuk peternakan.5
Di Queensland, Australia, 91% dari pembersihan seluruh pohon dalami periode 20 tahun lebih telah dilakukan untuk tempat merumput peternakan.6(recent report on a 20-year study commissioned by the Queensland government by Mr. Gerald Bisshop, retired principal scientist of the Queensland Department of Environment and Resources Management)
PENGGURUNAN
Penggurunan disebabkan oleh penggembalaan ternak yang berlebihan dan perluasan dari area menanam sumber makanan bagi peternakan.(TPN3 Rangeland Management in Arid Areas including the fixation of sand dunes, UNCCD, 2003)Lebih dari 50% erosi tanah di Amerika Serikat disebabkan oleh peternakan, yang menyebabkan penggurunan.7
Lebih dari 50% erosi tanah di Amerika Serikat disebabkan oleh peternakan, yang menyebabkan penggurunan.8
Sekitar 75 juta ton humus tererosi setiap tahunnya dikarenakan kesalahan manajemen pertanian, perubahan iklim, dan penggembalaan ternak. Hanya di Amerika Serikat saja, 54% humus habis karena penggembalaan yang berlebihan, dengan lebih dari 100 ton humus hilang per hektar setiap tahunnya..9 (A study presented by Professor John Crawford at the recent Carbon Farming Conference held in New South Wales, Australia)
Pada 2010, Irak, China, Chad, Australia dan Mongolia, di antara negara lainnya, dilaporkan mengalami kekeringan yang parah, dengan penggembalaan peternakan membuat kondisi semakin parah.
