How does making beer cause pollution?

Beer production can lead to pollution through various processes, including water usage, wastewater generation, and emissions from energy consumption. The brewing process requires significant amounts of water, which can strain local water resources. Additionally, the discharge of wastewater containing organic matter and nutrients can contaminate local waterways, leading to eutrophication. Lastly, the energy-intensive nature of brewing often results in greenhouse gas emissions, contributing to air pollution.
