Why is polythene difficult to dispose of?

Polythene, or polyethylene, is difficult to dispose of because it is not biodegradable, meaning it does not break down naturally in the environment. Its durability and resistance to degradation can lead to significant accumulation in landfills and oceans, contributing to pollution and harming wildlife. Additionally, recycling polythene can be challenging due to contamination and the need for specialized facilities, which limits its recycling rates.
