La cría de ganado es una de los principales conductores a la deforestación.4(ONU FAO, 2006)
Desde los años 1990 aproximadamente el 90% de la deforestación del Amazonas han sido debido a la tala de tierra para el pastoreo del ganado o crecimiento de alimento para el ganado.5
En Australia, el 91% de todos los árboles talados en un periodo de 20 años ha sido para el pastoreo del ganado.6(reporte reciente eun estudio de 20 años encargado para el gobierno de Queensland por el Sr. Gerald Bisshop, científico principal retirado del Departamento del Ambiente y Manejo de Recursos de Queensland)
DESERTIFICACIÓN
La desertificación es causada por el pastoreo excesivo y la expansión de áreas de cultivo para el ganado.7 (TPN3 Manejo de Pastizales en Áreas Áridas incluyendo la fijación de dunas de arena, UNCCD, 2003)
Cerca del 50% de la erosión del suelo del mundo es causado por la ganadería, que lleva a la desertificación.8
Cerca de 75.000 millones de toneladas de suelo fértil están siendo erosionados anualmente debido al mal manejo agrícola, al cambio climático y al pastoreo del ganado. Solo en los Estados Unidos, el 54% de la tierra de pastizales está con sobrepastoreo, con más de 100 toneladas de suelo fértil perdido por hectárea por año.9 (Un estudio presentado por el profesor John Crawford en la reciente Conferencia de Cultivo de Carbono llevada a cabo en New South Wales, Australia)
En el 2010, Irak, China, Chad, Australia, y Mongolia, entre otros, se reportaron serias sequías, con el pastoreo del ganado haciendo las condiciones peores.
