【Abstract】 With beef production as its essential part and mostly based on overfeeding of fine feed with low ecological efficiency, modern animal husbandry has been consuming 40% of world cereal production, resulting in serious water and land pollution and aggravating the global green house effect. In this paper, a systematic survey of the beef production industry is carried out, with emphasis on related resources and environmental problems. A corresponding EIA technique is introduced and sustainable patterns for beef production are explored particularly for China.更多还原
