The environmental impacts of plastic bags are profound and multifaceted. One of the most pressing issues is their contribution to pollution, particularly in marine environments. Plastic bags can take hundreds of years to decompose, leading to accumulation in oceans and waterways, where they pose a threat to wildlife. Animals often mistake plastic bags for food, which can result in injury or death. Additionally, the production of plastic bags involves the extraction of fossil fuels, contributing to greenhouse gas emissions and climate change. Efforts to mitigate these impacts include promoting reusable bags and implementing bans or fees on single-use plastic bags in various regions.
