Question map
Consider the following statements : Statement-I : Many chewing gums found in the market are considered a source of environmental pollution. Statement-II : Many chewing gums contain plastic as gum base. Which one of the following is correct in respect of the above statements ?
Explanation
The correct answer is option A because both statements are correct and Statement-II directly explains Statement-I.
The overwhelming majority of commercially available chewing gum in the UK contains plastic-based synthetic polymers, and discarded gums release microplastics into soil and water, posing ecological risks.[1] Chewing gum is a "significant but overlooked" source of microplastic ingestion and environmental pollution, with a single piece of plastic gum releasing in excess of 250,000 microplastic particles, and chewing gum residues persisting in the environment for 5 to 500 years.[2]
The overwhelming majority of commercially available chewing gum in the UK contains plastic-based synthetic polymers hidden within the ingredients under the term 'gum base'.[3] Many widely sold types of gum use ingredients like polyethylene β similar to the plastic used to make shopping bags β as part of their "gum base," and some gum makers also use ingredients such as polyvinyl[4] acetate, commonly used in glue, or styrene-butadiene rubber, similar to what's found in tires.[4]
The causal relationship is clear: the plastic content in gum base is precisely why chewing gum causes environmental pollution through microplastic release and persistence, making Statement-II a direct explanation of Statement-I.

PROVENANCE & STUDY PATTERN
Full viewThis is a 'Hidden Plastic' question testing applied environmental awareness rather than bookish knowledge. The strategy is to recognize that mass-produced, non-biodegradable consumer goods (like cheap gum) are almost invariably synthetic polymers. If it doesn't rot, it's likely plastic.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Statement 1: Are many commercially available chewing gums considered sources of environmental pollution?
- Statement 2: Do many commercially available chewing gums contain plastic (synthetic polymers) as their gum base?
- Statement 3: Is the plastic content of chewing-gum gum base the main explanation for chewing gum causing environmental pollution?
- States that an "overwhelming majority of commercially available chewing gum in the UK contains plastic-based synthetic polymers," linking many commercial gums to plastics.
- Explicitly notes discarded gums "release microplastics into soil and water, posing ecological risks," tying commercial gum composition to environmental pollution.
- Mentions long environmental persistence (5 to 500 years), supporting the pollution concern.
- Describes chewing gum as a "significant but overlooked" source of microplastic ingestion and environmental pollution.
- Provides a concrete measure of pollution potential: a single piece can "release in excess of 250,000 microplastic particles."
- Notes gum residues are "highly persistent in the environment" (5 to 500 years), reinforcing long-term pollution impact.
- Reports research finding that "the chewing process causes the release of microplastics and nanoplastics," indicating commercial chewing leads to microplastic release.
- Explicitly states "the environment is under threat from plastic gums" and that residues are "highly persistent in the environment," connecting gum composition to environmental harm.
Defines 'non-biodegradable pollutants' (e.g., plastics) as those not decomposed by microbes β establishes that persistent materials cause longβterm pollution.
A student could check whether common gum bases are synthetic/nonβbiodegradable polymers; if so, by analogy they may behave like listed nonβbiodegradables and persist as pollutants.
Describes urban solid waste and small discarded items (plastics, containers) as sources of land pollution and nuisance in cities.
Combine this with the observable fact that chewed gum is often discarded in urban areas to judge whether it contributes to solidβwaste pollution and litter problems.
Gives a straightforward classification of pollution media (air, water, land), framing where a material like discarded gum would be counted (land/urban pollution).
Use this classification to narrow investigation to land/urban waste studies and to look for reports of gum as a land/litter pollutant.
Notes that traditional chewing gum component 'chicle' is a natural, plantβderived material (sap of zapota), implying some gums can be biodegradable.
A student could contrast brands with natural chicle vs. those listing industrial gum bases to infer which are more likely biodegradable or persistent.
States that natural 'gums' (from acacia, etc.) are used in the candy industry, showing there exist natural adhesive/gum substances used in food.
Compare ingredient lists of commercial gums to see how many use such natural gums versus synthetic bases to estimate potential for biodegradability and pollution.
- Explicitly states the prevalence: calls out the "overwhelming majority of commercially available chewing gum in the UK" as containing plastic-based synthetic polymers.
- Specifically ties those synthetic polymers to the ingredient label term 'gum base', explaining how the plastic is hidden from consumers.
- Describes that many widely sold gums use specific plastics (e.g., polyethylene) as part of their 'gum base'.
- Names other synthetic polymers used (polyvinyl acetate, styrene-butadiene rubber), showing that multiple common plastics serve as gum bases.
- States directly that 'Most chewing gum is made from synthetic polymers', equating gum base materials with common plastics.
- Provides context/numbers indicating large-scale consumption of such plastic-containing gums (UK estimate), reinforcing that this is widespread.
Names a traditional chewing-gum base (Chicle) made from tree sap, showing gum bases can be natural polymers.
Compare historical natural gum-base examples with modern product ingredient lists to see if manufacturers now use alternative (synthetic) bases.
Lists natural gums (acacia, carob, mesquite) used in candy industry, implying that 'gum' material for confectionery has established natural sources.
Use this pattern (natural gums used in candy) to check whether modern commercial gum ingredient lists instead name synthetic polymers rather than these natural gums.
Discusses synthetic polymers as commercially used materials that require stabilizers for sunlight exposure, indicating synthetic polymers are widely applied in industry.
Given their broad industrial use, look for polymer names or stabilizer-related terms in gum ingredient panels as a sign of synthetic gum base use.
Notes presence of additives, plasticizers and fillers in plastics, showing that commercial plastics commonly contain such components.
If chewing-gum bases are synthetic, ingredient lists or safety/data sheets might mention plasticizers/fillersβsearch for those terms when examining gum products.
States plastics are widely used in packaging and consumer goods due to cost and convenience, suggesting substitution of plastics for traditional materials is common in modern products.
Apply this substitution tendency to suspect that low-cost commercial gums might replace natural chicle with synthetic polymer bases; then verify via ingredient labels or manufacturer info.
- Explicitly states gum base is effectively 'a lump of malleable plastic', linking gum base composition to plastic.
- Notes manufacturers hide composition by listing the vague term 'gum base', implying plastic content is a hidden but central factor.
- Names specific plastics (polyethylene, polyvinyl acetate, styrene-butadiene rubber) used as part of 'gum base', directly tying common plastic polymers to gum base.
- Describes gum base ingredients as similar to everyday plastics (shopping bags, glue, tyres), supporting the idea that plastic content explains pollution and microplastic release.
- States synthetic chewing gum does not biodegrade and can persist in the environment for many years, linking synthetic (plastic) gum base to long-term pollution.
- Explains environmental fate: it hardens, cracks and breaks down into microplastics, which is a direct pollution mechanism stemming from plastic gum base.
Gives a clear general rule that plastics are non-biodegradable pollutants (listed alongside glass, heavy metals, etc.).
A student could use this to ask whether typical gum bases are plastic-like and therefore persistent in the environment.
Describes problems from plastic waste in land environments (drain choking, animal ingestion, additives/plasticizers present).
A student might check if discarded gum behaves like other plastic litter (sticks to surfaces, resists degradation) and whether additives in gum base match those concerns.
Lists harms from plastics including animal health effects and toxic by-products when burned, showing mechanisms by which plastics cause pollution.
One could compare those mechanisms (ingestion, burning, leaching) with documented impacts of discarded chewing gum.
Gives an example of a natural gum base (chicle from zapota tree), showing gum bases are not necessarily synthetic plastics.
A student could use this to reason that if some gum bases are natural, plastic content cannot be assumed universal and must be checked by product type or era.
Notes that gums (from plants) are used in the candy industry, implying a variety of gum materials and uses.
A student could survey whether modern commercial chewing gum formulations tend toward plant-derived bases or synthetic/plastic bases to evaluate the plausibility that plastics are the main cause.
- [THE VERDICT]: **Logical Sitter**. While not explicitly in textbooks, the link between 'modern industrial gum' and 'synthetic polymers' is a standard deduction in the Microplastics theme.
- [THE CONCEPTUAL TRIGGER]: **Microplastics & Hidden Polymers**. The syllabus theme is 'Environmental Pollution > Solid Waste', specifically focusing on items that bypass Single-Use Plastic (SUP) bans but still pollute.
- [THE HORIZONTAL EXPANSION]: **Hidden Plastics List**: 1. **Cigarette Butts** (Cellulose Acetate filters - #1 litter); 2. **Wet Wipes** (Polyester blends - cause sewer fatbergs); 3. **Paper Cups** (LDPE lining - not recyclable with paper); 4. **Tea Bags** (Polypropylene sealants); 5. **Synthetic Textiles** (Microfibers from washing).
- [THE STRATEGIC METACOGNITION]: Stop memorizing definitions of pollution and start auditing your daily life. Ask: 'Is this βΉ1 item natural or synthetic?' If it's cheap, stretchy, and waterproof, it is petrochemical-based. UPSC targets the gap between consumer perception (it's food) and material reality (it's plastic).
Whether a discarded item becomes persistent pollution depends on its biodegradability; non-biodegradable materials (e.g., plastics, glass) persist in the environment.
High-yield for UPSC because questions often ask about types and behaviour of pollutants; links to waste management, urban sanitation and policy responses. Mastering this helps answer questions on persistence, cleanup and prevention strategies.

Cigarette Filters (Cellulose Acetate). Like gum, they are often mistaken for biodegradable paper/cotton but are actually a form of plastic that persists for decade. Expect a question linking 'Cellulose Acetate' to environmental persistence.
Use the **'Scale of Economy' Logic**. NCERT Human Geography mentions 'Chicle' (natural gum) comes from the Zapota tree. Harvesting tree sap is labor-intensive and expensive. For chewing gum to be sold globally for βΉ1 or βΉ5, the raw material *cannot* be natural chicle; it must be a cheap industrial substitute. Cheap industrial substitutes for rubbery materials are almost always synthetic plastics. Thus, Statement II is correct.
Mains GS-3 (Environment) + GS-2 (Governance): Link this to **Extended Producer Responsibility (EPR)**. Just as electronics manufacturers manage e-waste, should gum and cigarette companies be financially liable for the municipal cost of cleaning litter? This is a key debate in Urban Waste Management.
