Detailed Explanation:

Answer: Option 1 — Both Statement-I and Statement-II are correct and Statement-II explains Statement-I

Chewing gums are a significant source of environmental pollution, and Statement-II directly explains why this is the case.

✅ Statement-I – Correct: Many chewing gums found in the market are considered a source of environmental pollution due to their non-biodegradable nature and improper disposal, leading to persistent litter in public spaces.

✅ Statement-II – Correct: Many chewing gums contain plastic polymers (such as polyisobutylene, polyvinyl acetate, or polyethylene) as their gum base, which makes them non-biodegradable and environmentally persistent.

Explanation: Statement-II explains Statement-I because the presence of plastic-based gum base is the primary reason why chewing gums become environmental pollutants. These synthetic polymers do not decompose naturally and remain in the environment for years, creating cleanup challenges and contributing to plastic pollution.

📝 Short Notes: Chewing Gum and Environmental Pollution

• Gum Base Composition: Modern chewing gums typically use synthetic polymers (plastics) like polyisobutylene and polyvinyl acetate instead of natural chicle latex.
• Non-Biodegradable Nature: These plastic-based gum bases can take years to decades to break down in the environment, persisting as microplastic pollution.
• Urban Pollution: Discarded chewing gum is one of the most common forms of street litter, requiring expensive removal processes (often using chemical solvents or freezing techniques).
• Environmental Impact: Improperly disposed gum contributes to plastic pollution, can harm wildlife if ingested, and creates unsightly stains on pavements and public infrastructure.
• Biodegradable Alternatives: Some companies are now developing plant-based, biodegradable gum alternatives to address environmental concerns.
