Abstract
The intensification of animal production systems in recent decades has made it possible to satisfy the growing world demand for meat products, but has also generated significant environmental challenges. This study aims to review the environmental impacts of these systems, exploring areas such as greenhouse gas (GHG) emissions, soil and water contamination, and high resource consumption. A literature review was conducted in academic databases, focusing on recent studies on these issues. The results show that intensive systems are responsible for high CO₂, CH₄ and N₂O emissions, contributing to climate change. There is also a high demand for water and land for growing fodder crops, which drives deforestation, in addition to inadequate waste management practices that affect air quality and public health. The discussion highlights the urgency of implementing more sustainable technologies in waste treatment and natural resource management to mitigate these impacts. In conclusion, the transition to more responsible and sustainable production practices is fundamental to reduce the environmental impact of intensive livestock production.
