What is the meaning of "ecological withdrawals" in the following context?
This groundbreaking text provides students with an overview and assessment of green criminology as well as a call to action. Green Criminology draws attention to the ways in which the political-economic organization of capitalism causes ecological destruction and disorganization. Focusing on real-world issues of green crime and environmental justice, chapters examine ecological withdrawals, ecological additions, toxic towns, wildlife poaching and trafficking, environmental laws, and nongovernmental environmental organizations. The book also presents an unintimidating introduction to research from the physical sciences on issues such as climate change, pollution levels, and the ecological footprint of humans, providing a truly interdisciplinary foundation for green criminological analysis.
