I. Overview
Littering in the Philippines is not merely a matter of public discipline or sanitation. It is a legally punishable act governed by national environmental laws, local ordinances, and special regulations applicable to public places, roads, waterways, parks, transport terminals, and communities.
The legal framework against littering reflects the State policy to protect public health, preserve ecological balance, maintain cleanliness, prevent flooding, and promote responsible waste management. In practice, penalties may come from national statutes such as the Ecological Solid Waste Management Act of 2000, local anti-littering ordinances, barangay regulations, and rules issued by government agencies or public authorities.
Littering penalties in the Philippines can include fines, community service, clean-up duties, imprisonment in more serious cases, administrative sanctions, or a combination of these, depending on the law violated, the place where the act was committed, and whether the offender is an individual, business establishment, or public official.
II. Meaning of Littering
In ordinary legal and regulatory usage, littering refers to the improper throwing, dumping, leaving, or scattering of waste in a place where it should not be disposed of.
Common examples include throwing or leaving:
- Candy wrappers, plastic bags, bottles, cups, sachets, and food containers;
- Cigarette butts;
- Paper, flyers, cartons, and packaging;
- Household garbage on streets or vacant lots;
- Construction debris in unauthorized areas;
- Waste into canals, rivers, beaches, drainage systems, or public roads;
- Garbage outside the prescribed collection schedule or designated disposal area.
Littering is usually treated as a form of improper solid waste disposal. Depending on the facts, it may also overlap with illegal dumping, obstruction of waterways, public nuisance, violation of sanitation rules, or breach of a local environmental ordinance.
III. Constitutional and Policy Basis
The Philippine Constitution recognizes the right of the people to a balanced and healthful ecology. This constitutional policy supports environmental laws and government regulations against improper waste disposal.
Littering laws are also connected to the State’s police power. The government may regulate individual behavior in public spaces to protect public health, safety, convenience, and general welfare. Because littering affects drainage, sanitation, flood control, disease prevention, tourism, and public order, the government has broad authority to penalize it.
IV. National Law: Republic Act No. 9003
The principal national law relevant to littering is Republic Act No. 9003, or the Ecological Solid Waste Management Act of 2000.
RA 9003 establishes a comprehensive system for ecological solid waste management. It requires waste segregation, collection, recycling, composting, materials recovery, and proper disposal. It also prohibits acts that contribute to improper waste disposal.
A. Prohibited Acts Related to Littering
Under RA 9003, prohibited acts include improper disposal and mishandling of solid waste. Acts commonly associated with littering may fall under the law’s prohibitions, such as:
- Littering, throwing, dumping, or placing waste in public places, including roads, sidewalks, canals, parks, vacant lots, rivers, and other non-designated areas;
- Open dumping of solid waste;
- Open burning of solid waste;
- Dumping waste into waterways;
- Non-segregation of waste where segregation is required;
- Operating or allowing unauthorized disposal sites;
- Transporting or dumping garbage in prohibited locations;
- Failure of establishments or institutions to comply with solid waste management requirements.
The specific charge may depend on whether the act is simple littering, illegal dumping, open dumping, or violation of waste segregation and collection rules.
B. Penalties Under RA 9003
RA 9003 imposes penalties that may include fines, imprisonment, or both. The amount and severity depend on the specific prohibited act.
For acts such as littering or dumping waste in public places, the law generally authorizes monetary penalties and, in some cases, imprisonment. More serious violations, such as operating open dumps or causing large-scale illegal disposal, may carry heavier penalties.
Aside from criminal penalties, violators may also be required to perform remedial or clean-up actions. Businesses and institutions may face additional sanctions, including closure orders, permit consequences, or administrative penalties, depending on the violation and the implementing authority.
V. Local Government Ordinances
Although national law provides the broad legal framework, most day-to-day enforcement of littering penalties happens through city, municipal, or barangay ordinances.
Local government units, or LGUs, have authority under the Local Government Code to enact ordinances for sanitation, environmental protection, public order, and waste management. As a result, penalties for littering vary from place to place.
A. Common Local Penalties
Local anti-littering ordinances commonly impose:
- Fines for first, second, and subsequent offenses;
- Community service, often involving street sweeping, clean-up drives, or waste collection assistance;
- Attendance in environmental seminars;
- Confiscation of items used in violation, where applicable;
- Issuance of citation tickets;
- Administrative penalties for establishments;
- Business permit consequences for repeated or serious violations.
Some cities impose escalating penalties. A first offense may involve a smaller fine or community service, while repeat offenses may result in higher fines, longer community service, or possible court action.
B. Barangay Ordinances
Barangays may also adopt ordinances against littering and improper disposal of waste. These may regulate:
- Garbage collection schedules;
- Segregation of biodegradable, recyclable, residual, and special waste;
- Designated collection points;
- Prohibition against dumping in canals, roads, alleys, and vacant lots;
- Cleanliness duties of households and establishments;
- Penalties for non-compliance.
Barangay officials, tanods, environmental officers, or deputized enforcers may issue warnings, citations, or refer violations to the city or municipality.
VI. Metro Manila and Urban Enforcement
In highly urbanized areas, anti-littering enforcement is often stricter because litter contributes to flooding, drainage blockage, traffic-related sanitation problems, and pollution of waterways.
Metro Manila cities typically maintain their own anti-littering and solid waste ordinances. Enforcement may be carried out by local environmental offices, traffic enforcers, barangay personnel, market administrators, park authorities, and deputized officers.
Common violations in urban areas include:
- Throwing cigarette butts on sidewalks;
- Leaving food containers in public transport terminals;
- Dumping household garbage outside collection hours;
- Throwing waste into drainage canals;
- Leaving construction debris on roads;
- Disposing waste in creeks, esteros, or riverbanks;
- Failure of establishments to maintain clean frontage areas.
Urban ordinances may also require owners or occupants to keep sidewalks, gutters, and property frontages clean.
VII. Littering in Waterways, Canals, Rivers, and Coastal Areas
Littering becomes more serious when waste is thrown into waterways. This includes rivers, esteros, canals, drainage systems, beaches, lakes, and coastal waters.
Such acts may violate not only anti-littering ordinances and RA 9003, but also laws and regulations on water pollution, flood control, public works, sanitation, and environmental protection.
Waste thrown into waterways can cause:
- Clogged drainage systems;
- Urban flooding;
- Water pollution;
- Marine pollution;
- Health hazards;
- Damage to aquatic ecosystems;
- Increased government clean-up costs.
Depending on the facts, enforcement may involve local governments, the Department of Environment and Natural Resources, the Metropolitan Manila Development Authority in Metro Manila, barangay officials, or other agencies.
VIII. Littering in Public Utility Vehicles, Roads, and Transport Terminals
Throwing waste from vehicles, leaving garbage in public utility vehicles, or littering in transport terminals may be punishable under local ordinances, traffic-related regulations, or rules of terminal operators.
Examples include:
- Throwing plastic cups or food wrappers from a jeepney, bus, taxi, tricycle, or private car;
- Leaving trash inside public utility vehicles;
- Dumping waste at bus stops, jeepney terminals, ports, airports, or railway stations;
- Throwing cigarette butts on roads or sidewalks.
The offender may be cited directly. In some cases, vehicle operators, drivers, or establishments may also have duties to maintain cleanliness within their premises or vehicles.
IX. Cigarette Butts and Smoking-Related Litter
Cigarette butts are among the most common forms of litter. Even when small, they may be treated as solid waste and penalized under anti-littering ordinances.
Smoking-related litter may also overlap with no-smoking ordinances. For example, a person who smokes in a prohibited public place and discards a cigarette butt on the ground may commit two separate violations:
- Violation of smoking regulations; and
- Violation of anti-littering or cleanliness rules.
Local rules may impose separate fines for each offense.
X. Illegal Dumping Distinguished from Simple Littering
Simple littering usually involves smaller amounts of waste, such as wrappers, bottles, cigarette butts, or food containers. Illegal dumping generally involves larger quantities of waste, such as sacks of household garbage, construction debris, commercial waste, or waste transported and discarded in unauthorized areas.
Illegal dumping is treated more seriously because it may involve deliberate disposal, repeated conduct, or larger environmental harm.
Factors that may increase liability include:
- Volume of waste;
- Type of waste;
- Location of dumping;
- Whether the act was repeated;
- Whether a vehicle was used;
- Whether the offender is a business or contractor;
- Whether the waste reached waterways or protected areas;
- Whether hazardous or special waste was involved.
XI. Hazardous, Medical, and Special Waste
Littering becomes more legally serious when the waste involved is hazardous, infectious, toxic, chemical, or otherwise regulated.
Examples include:
- Used syringes;
- Medical waste;
- Chemicals;
- Batteries;
- Electronic waste;
- Used oil;
- Pesticide containers;
- Industrial waste;
- Hazardous household materials.
These may fall under additional laws and regulations beyond ordinary littering rules. Penalties can be heavier because such waste poses risks to human health and the environment.
Businesses, clinics, laboratories, factories, and contractors may face stricter duties for storage, transport, treatment, and disposal.
XII. Liability of Individuals
An individual may be penalized for littering if he or she personally throws, leaves, dumps, or abandons waste in a prohibited place.
The usual elements are:
- The person discarded or placed waste;
- The place was public, unauthorized, or not a designated disposal area;
- The act violated a law, ordinance, rule, or posted regulation.
Intent is not always difficult to prove. Many littering offenses are treated as regulatory violations. An enforcer may rely on direct observation, admission, CCTV footage, witness statements, or physical evidence.
Common defenses may include mistaken identity, lack of proof, emergency circumstances, unclear signage where signage is required, or proof that the person did not commit the act. However, mere inconvenience or absence of a nearby trash bin is generally not a legal justification.
XIII. Liability of Households
Households may be penalized for improper garbage disposal, especially where local rules require segregation and disposal only during specified collection times.
Common household violations include:
- Placing garbage outside the allowed collection schedule;
- Failure to segregate waste;
- Dumping waste in vacant lots or canals;
- Burning waste;
- Refusing to comply with barangay waste collection rules;
- Leaving garbage in front of another person’s property.
In some LGUs, homeowners’ associations and condominium corporations also impose internal waste management rules, which may be enforced separately from government penalties.
XIV. Liability of Business Establishments
Businesses have heightened responsibilities because they generate commercial waste and are subject to permits and inspections.
Establishments may be liable for:
- Failure to provide proper trash receptacles;
- Allowing customers or employees to litter within or around the premises;
- Improper disposal of commercial waste;
- Dumping waste outside collection schedules;
- Failure to segregate waste;
- Obstruction of sidewalks with garbage;
- Discharge of waste into drainage systems;
- Failure to keep frontage areas clean.
Repeated violations may affect business permits, sanitary permits, environmental compliance requirements, or local clearances.
Food establishments, markets, malls, transport terminals, construction sites, and manufacturing facilities are usually subject to stricter monitoring.
XV. Liability of Public Officials and Government Units
RA 9003 and local waste management laws also impose duties on local governments and responsible officials. LGUs are required to implement solid waste management systems, maintain collection services, establish materials recovery facilities where applicable, close or rehabilitate illegal dumps, and enforce waste rules.
Public officials may face administrative consequences for failure to perform mandatory duties, particularly where non-enforcement leads to public health or environmental harm.
This does not mean every instance of littering creates official liability. However, persistent failure to implement waste management laws may raise administrative, political, or legal accountability issues.
XVI. Enforcement Officers
Depending on the locality and the place involved, littering laws may be enforced by:
- Barangay officials;
- Barangay tanods;
- City or municipal environmental officers;
- Sanitation inspectors;
- Traffic enforcers;
- Market administrators;
- Park officers;
- MMDA personnel in Metro Manila where applicable;
- Police officers;
- Deputized environmental enforcers;
- Personnel of public transport terminals, ports, airports, or public facilities;
- DENR or other environmental authorities for more serious environmental violations.
Local ordinances usually identify who may issue citation tickets and what procedure must be followed.
XVII. Citation Tickets and Ordinance Violation Receipts
Many LGUs enforce anti-littering rules through citation tickets, sometimes called ordinance violation receipts.
A citation typically states:
- Name of the offender;
- Date and time of violation;
- Place of violation;
- Specific ordinance or rule violated;
- Fine or penalty;
- Deadline and place for payment;
- Consequences of non-payment;
- Whether community service is required;
- Name and authority of the apprehending officer.
Failure to pay the fine or comply with the citation may lead to further legal action, higher penalties, or filing of a complaint before the appropriate office or court, depending on the ordinance.
XVIII. Due Process Rights of the Alleged Violator
Even though littering is often treated as a minor offense, an alleged violator still has basic rights.
These include:
- The right to know the violation charged;
- The right to question the citation through the procedure provided by law or ordinance;
- The right not to be penalized without legal basis;
- The right to contest mistaken identity or factual errors;
- The right to be treated without abuse, extortion, or harassment;
- The right to official receipts for payments made.
An enforcer cannot lawfully collect unofficial payments or impose penalties not authorized by law or ordinance.
XIX. Community Service as a Penalty
Many Philippine anti-littering ordinances use community service as an alternative or additional penalty. This is common because the offense directly affects public cleanliness.
Community service may include:
- Street sweeping;
- Drainage or canal clean-up;
- Participation in barangay clean-up drives;
- Waste segregation work;
- Environmental awareness seminars;
- Cleaning parks, markets, terminals, or public facilities.
Community service must be authorized by the relevant law or ordinance and should be implemented in a manner consistent with human dignity and safety.
XX. Imprisonment
Some waste-related violations may carry imprisonment, especially under national environmental laws or more serious local ordinance violations.
Imprisonment is more likely where:
- The law expressly provides it;
- The offender repeatedly violates the law;
- The offense involves illegal dumping rather than simple littering;
- The waste is hazardous or harmful;
- The violation causes serious public health or environmental consequences;
- The offender refuses to comply with lawful orders;
- The matter proceeds to court.
For simple littering, LGUs often prioritize fines, community service, or both. However, the possibility of imprisonment should not be dismissed where the governing law allows it.
XXI. Minors and Littering
If the offender is a minor, enforcement may be handled differently. Authorities may involve parents, guardians, school officials, barangay officials, or social welfare officers, depending on the situation and age of the child.
Penalties against minors must be consistent with laws on child protection, juvenile justice, and local procedures. In many cases, corrective or educational measures are preferred over punitive treatment.
Parents or guardians may sometimes be held responsible under local ordinances, particularly for repeated violations or failure to supervise, but this depends on the specific ordinance.
XXII. Littering in Schools
Schools may enforce anti-littering rules under student discipline policies. These are separate from government penalties.
Possible school sanctions include:
- Warnings;
- Clean-up duty;
- Conduct marks;
- Parent conferences;
- Environmental awareness activities;
- Disciplinary action under the student handbook.
If the littering occurs outside the school but within public areas, local ordinances may still apply.
XXIII. Littering in Private Property
Littering on private property may lead to different legal consequences. If a person throws garbage onto another person’s land, the act may be treated as:
- Trespass-related misconduct;
- Private nuisance;
- Damage to property;
- Violation of sanitation ordinances;
- Illegal dumping;
- Civil liability for clean-up costs.
The property owner may report the matter to the barangay, LGU, police, or court, depending on seriousness.
In subdivisions, condominiums, malls, offices, and private facilities, internal rules may also apply. These may result in fines, loss of privileges, or administrative sanctions.
XXIV. Open Burning of Waste
Open burning is closely related to improper waste disposal and is prohibited under environmental and clean air regulations.
Burning household garbage, plastics, leaves mixed with waste, packaging, rubber, or other refuse may violate national and local laws. It can create air pollution, toxic smoke, and fire hazards.
Penalties for open burning may be separate from littering penalties and can be more serious, especially if the burning creates health hazards or damages property.
XXV. Waste Segregation Rules
Anti-littering policy in the Philippines is connected to waste segregation. RA 9003 promotes segregation at source and requires systems for biodegradable, recyclable, residual, and special wastes.
Failure to segregate may be penalized by local ordinances even if the waste is not literally thrown on the street. For example, a household or business may violate local rules by placing mixed waste for collection when segregation is mandatory.
Common categories include:
- Biodegradable waste – food scraps, garden waste, organic matter;
- Recyclable waste – bottles, paper, cardboard, metals, certain plastics;
- Residual waste – non-recyclable and non-compostable waste;
- Special waste – batteries, bulbs, e-waste, chemicals, and similar materials.
Waste segregation violations may lead to refusal of collection, fines, warnings, or community service.
XXVI. Public Nuisance and Civil Liability
Littering or dumping may create a public or private nuisance. A nuisance is something that injures or endangers health, obstructs public passage, offends the senses, or interferes with the use of property.
Large piles of garbage, foul odors, blocked drainage, stagnant water, and pest infestation may result in nuisance proceedings.
Possible consequences include:
- Order to remove the waste;
- Clean-up at the offender’s expense;
- Civil damages;
- Administrative sanctions;
- Criminal or ordinance penalties.
Where littering causes actual damage, such as flooding caused by blocked drainage, the offender may face additional liability if causation can be proven.
XXVII. Environmental Impact of Littering Recognized by Law
Philippine waste laws recognize that littering is harmful beyond the small act itself. Litter can:
- Block canals and drainage systems;
- Contribute to flooding;
- Pollute rivers and seas;
- Harm animals and marine life;
- Spread disease;
- Increase government clean-up costs;
- Damage tourism and public spaces;
- Lower quality of life in communities;
- Create fire hazards;
- Encourage further dumping.
This is why even small acts, such as throwing a wrapper or cigarette butt, may be penalized.
XXVIII. Relationship Between National Law and Local Ordinances
National law provides the general framework, while local ordinances supply specific rules, fines, procedures, and enforcement mechanisms.
A person may violate both national law and a local ordinance, but actual prosecution or citation usually depends on enforcement discretion and the facts.
For ordinary street littering, local ordinances are the most commonly used basis for penalties. For larger or more harmful acts, national laws may become more relevant.
Where a local ordinance conflicts with national law, national law prevails. However, LGUs may generally impose stricter or more specific rules as long as they remain within legal authority.
XXIX. Procedure After Apprehension
The usual process for a littering violation is:
- An authorized enforcer observes or verifies the violation;
- The enforcer identifies the offender;
- A citation ticket or notice of violation is issued;
- The offender is informed of the penalty and compliance procedure;
- The offender pays the fine, performs community service, attends a seminar, or contests the citation;
- Failure to comply may result in additional action.
In more serious cases, the matter may be referred for investigation, administrative action, or court proceedings.
XXX. Contesting a Littering Citation
A person who believes a citation was wrongly issued may contest it through the process provided by the LGU or issuing authority.
Grounds may include:
- The person did not commit the act;
- The enforcer identified the wrong person;
- The alleged act did not occur in a covered area;
- The cited ordinance does not apply;
- The citation contains material errors;
- The penalty imposed is not authorized;
- The enforcer lacked authority;
- Evidence is insufficient.
The person should keep the citation, receipts, photos, witness information, and any relevant evidence.
XXXI. Evidence in Littering Cases
Evidence may include:
- Personal observation by an enforcer;
- CCTV footage;
- Photographs or videos;
- Witness statements;
- Physical waste recovered;
- Vehicle plate numbers;
- Business records;
- Garbage bags or identifying materials;
- Admissions by the offender;
- Reports from barangay or sanitation personnel.
In small ordinance violations, direct observation by an authorized enforcer is often enough to issue a citation, subject to the violator’s right to contest it.
XXXII. Penalties for Repeat Offenders
Repeat offenders are usually treated more severely. Local ordinances often impose escalating penalties.
A common structure is:
- First offense: warning, lower fine, seminar, or short community service;
- Second offense: higher fine and longer community service;
- Third and subsequent offenses: maximum fine, longer community service, possible court action, or permit consequences for businesses.
Repeat violations by establishments may trigger inspections, closure proceedings, or non-renewal issues for permits.
XXXIII. Responsibility of Property Owners and Occupants
Local ordinances may require property owners, occupants, lessees, or business operators to keep their frontage, sidewalks, and immediate surroundings clean.
This responsibility may include:
- Sweeping the frontage area;
- Removing garbage placed near the property;
- Preventing obstruction of sidewalks;
- Providing proper receptacles;
- Coordinating with waste collectors;
- Preventing illegal dumping on the premises.
A property owner is not automatically liable for all waste dumped by strangers, but failure to address persistent unsanitary conditions may create liability under nuisance, sanitation, or local cleanliness rules.
XXXIV. Littering During Public Events
Public events such as fiestas, concerts, rallies, parades, markets, sports events, and religious gatherings often generate large amounts of waste.
Organizers may be required to:
- Provide trash bins;
- Coordinate with the LGU for waste collection;
- Maintain cleanliness during and after the event;
- Clean the venue after use;
- Prevent dumping or obstruction;
- Comply with environmental permits or local event conditions.
Individuals attending the event may still be personally liable for littering.
XXXV. Construction Debris and Contractor Liability
Construction waste is not ordinary street litter. It may include cement bags, rubble, wood, tiles, wires, metal scraps, soil, and demolition debris.
Improper disposal of construction debris may violate:
- Local anti-littering ordinances;
- Building permit conditions;
- Road obstruction rules;
- Solid waste laws;
- Drainage and flood control regulations;
- Subdivision or property rules.
Contractors, property owners, haulers, or project managers may be held responsible.
XXXVI. Waste Haulers and Transporters
Waste haulers may be liable if they transport and dump waste in unauthorized areas. Liability may arise from:
- Lack of permits;
- Dumping at illegal sites;
- Spillage during transport;
- Failure to cover loads;
- Mixing prohibited waste;
- Disposal outside approved facilities;
- Falsified disposal records.
Commercial waste disposal is more regulated than ordinary household disposal because of the volume and potential environmental harm.
XXXVII. Enforcement Challenges
Despite the existence of laws, littering remains common due to:
- Inconsistent enforcement;
- Lack of public awareness;
- Insufficient trash bins;
- Irregular garbage collection;
- Weak prosecution;
- Limited personnel;
- Public tolerance of minor violations;
- Poverty and informal settlements with inadequate waste services;
- Lack of proper disposal facilities;
- Poor coordination among agencies.
However, weak enforcement does not make littering lawful. It only affects the likelihood of apprehension.
XXXVIII. Common Misconceptions
1. “Small trash is not illegal.”
Even small items such as candy wrappers, cigarette butts, and receipts may constitute littering.
2. “It is allowed if there is no trash bin nearby.”
Lack of a nearby trash bin is generally not a legal excuse.
3. “Only barangays can enforce littering rules.”
Cities, municipalities, environmental officers, traffic enforcers, sanitation officers, and deputized personnel may also enforce rules depending on the ordinance.
4. “Businesses are not responsible for customer litter.”
Businesses may be required to maintain cleanliness within and around their premises, especially if local rules impose frontage or sanitation duties.
5. “Paying a fine means the act is not serious.”
Payment resolves the particular citation only if allowed by the ordinance. Repeated violations may lead to heavier consequences.
6. “Garbage placed outside the house is no longer the owner’s responsibility.”
Improper placement, non-segregation, or disposal outside collection schedules may still be punishable.
XXXIX. Practical Legal Compliance
To avoid liability, individuals and establishments should:
- Dispose of waste only in designated bins or collection points;
- Follow barangay and LGU garbage collection schedules;
- Segregate waste as required;
- Avoid throwing waste from vehicles;
- Never dump garbage into canals, rivers, vacant lots, or roads;
- Avoid burning waste;
- Keep property frontages clean;
- Secure commercial or construction waste properly;
- Use authorized waste haulers;
- Keep receipts or proof of proper disposal when required;
- Train employees and household members on waste rules;
- Cooperate with barangay and LGU waste management programs.
XL. Legal Consequences Beyond Fines
The consequences of littering may extend beyond the immediate penalty. Possible additional effects include:
- Community service obligations;
- Court proceedings for non-payment or repeated violations;
- Administrative action against businesses;
- Permit complications;
- Clean-up costs;
- Civil liability for damage;
- Nuisance abatement;
- Public record of ordinance violation;
- Loss of access or privileges in private facilities;
- Disciplinary sanctions in schools or workplaces.
For businesses, the reputational impact can also be significant.
XLI. Conclusion
Littering penalties in the Philippines arise from a combination of national law, local ordinances, barangay rules, and special regulations governing public places, waterways, transport areas, schools, businesses, and private communities. The most important national law is RA 9003, but the most common enforcement mechanism is the local anti-littering ordinance.
The legal treatment of littering depends on the nature, place, volume, and consequences of the act. A small wrapper thrown on the sidewalk may result in a local citation, while dumping sacks of garbage into a canal, burning waste, or disposing of hazardous materials may trigger heavier penalties under environmental, sanitation, or criminal laws.
At its core, Philippine anti-littering law recognizes that waste disposal is not merely a private act. It affects public health, drainage, flooding, environmental quality, community order, and the constitutional right to a balanced and healthful ecology. Therefore, individuals, households, establishments, contractors, haulers, and public authorities all have legal responsibilities in preventing littering and improper waste disposal.
