Explain the environmental impact of non-biodegradable substances.

Non-biodegradable substances have a significant negative impact on the environment because they do not decompose naturally and persist for long periods.

One major impact is environmental pollution. Materials like plastic and synthetic chemicals accumulate in landfills, water bodies, and soil, leading to land and water pollution.

They also pose a threat to wildlife and marine life. Animals may ingest plastic or become entangled in waste, which can lead to injury or death.

Non-biodegradable substances can also cause soil degradation by reducing soil fertility and affecting the growth of plants. Toxic chemicals from such waste may leach into the soil and groundwater, contaminating natural resources.

Additionally, improper disposal methods such as burning can release harmful gases into the atmosphere, contributing to air pollution and health hazards.

Due to their long-lasting nature and harmful effects, non-biodegradable substances require proper management through recycling and controlled disposal.
