The document discusses several issues related to water usage and pollution from agricultural practices, particularly feedlots. It notes that 70% of water withdrawals go to agriculture but over half is wasted. Climate change is altering precipitation patterns and making water scarcer. Feedlots produce massive amounts of waste with no sewage systems, polluting groundwater. Laws like CERCLA and SARA were enacted to address hazardous waste sites but don't adequately regulate agricultural waste. Changes are needed to practices and policies around water usage, deforestation, feedlots, and waste management to improve sustainability.
