- The raw material of plastic bags is oil. Therefore, the more we use plastic bags, the more we waste oil - a non-renewable energy source.
- The petroleum-based plastic bags take decades to break down, so if they are not recycled they litter. It creates visual pollution: in the streets, on the beaches etc. Also, they can clog roadside drains, which could cause street flooding during heavy rainfall.
- Plastic bags can be recycled but it rarely happens: according to the United States Environmental Protection Agency, only 1% of plastic bags were recycled in 2000, against twenty percent for paper bags.
- They endanger wildlife and particularly sea life such as sea turtles and dolphins which can die of entanglement, suffocation, and ingestion because they assume that these bags are jellyfish.
