Biodegradable and non-biodegradable materials

The video discusses the biodegradability of paper and plastic bags, highlighting that paper bags decompose faster due to microorganisms, while plastic bags persist in the environment. It explains that biodegradable materials, like paper, meat, and fruit, can decompose but may cause disease and harmful gases. Non-biodegradable materials, such as plastic and glass, do not break down easily and can cause pollution if not disposed of properly. The video emphasizes the importance of recycling both types of materials to reduce environmental impact.
