Is plastic biodegradable or non-biodegradable?

Plastic is a non-biodegradable substance because it cannot be broken down by microorganisms into simpler, harmless substances. Most plastics are made from synthetic polymers derived from petroleum, which are resistant to natural decomposition processes.

As a result, plastic remains in the environment for hundreds of years without degrading completely. Instead of decomposing, it may break into smaller pieces known as microplastics, which can be harmful to soil, water, and living organisms.

Due to its non-biodegradable nature, improper disposal of plastic leads to environmental pollution, affecting ecosystems and wildlife. This is why reducing plastic use, recycling, and proper waste management are essential.
