Identifying Non-Biodegradable Materials

Non-biodegradable materials are those that do not break down naturally in the environment. Let's look at each option:

DDT: This is a pesticide that remains in the environment for a long time and does not decompose easily.
Vegetable peel: This is organic waste that decomposes quickly.
Cardboard: This material is biodegradable and breaks down over time.
