Lantern Festivals: Pretty Lights, Ugly Pollution?

Sky lantern festivals are a well-loved tradition in multiple cultures, with lanterns released into the sky to celebrate holidays, make wishes, or mourn the passing of a loved one. While these festivals may create a beautiful, magical scene, they also pose a serious threat to the environment and wildlife. The lanterns, made of paper, cloth, string, and wire or bamboo for support, can take a long time to decompose, with the wire frames known to strangle and harm animals. They also pose a significant fire hazard, having caused multiple wildfires and building fires. With growing awareness of their negative impact, sky lanterns have been banned in several countries and states.

Lantern festivals can cause litter

The litter from sky lanterns can fall on private property, causing inconvenience and negative impacts. Environmental groups, farmers, and farm organizations oppose the use of lanterns due to these dangers. Some countries and states have banned the sale and use of sky lanterns, while others are considering restrictions.

The threat of fire is also present, as sky lanterns have caused wildfires and structure fires. The lanterns are released into the sky and can travel great distances, making it difficult to control where they land. This lack of control poses a risk to both wildlife and human structures.

Some lantern festivals have implemented measures to mitigate the impact of litter. For example, the Water Lantern Festival prioritizes leaving no trace and conducts an in-depth clean-up process after each event, ensuring that all lanterns and existing trash are removed from the water.

However, not all lantern festivals take such precautions, and the potential for litter and pollution remains. The release of sky lanterns during festivals can result in debris that takes a long time to decompose, posing risks to wildlife and the environment. The wire frames can strangle animals, and the paper and bamboo parts can also cause harm when ingested by animals.

Additionally, the fire risk associated with sky lanterns cannot be overlooked. The lanterns can cause wildfires and structure fires, posing a danger to both human and animal life. The uncontrolled nature of sky lanterns, which can travel over a mile depending on the winds, makes it challenging to predict and prevent these fires.

Lanterns pose a risk to wildlife

Sky lanterns are a well-loved tradition in multiple cultures, often used to celebrate holidays, make wishes, or mourn the passing of a loved one. They are made of paper, cloth, and string, with wire or bamboo frames. While they create a beautiful, magical scene, they pose a serious threat to wildlife and the environment.

Firstly, sky lanterns can cause harm to wildlife when they fall back to the ground. The RSPCA in the UK is working to educate people about the dangers the lanterns pose to wildlife, particularly birds that can get entangled in the string or frames. Livestock and wildlife can also be harmed by ingesting the wire, which can damage the throat, stomach, and intestines, leading to immense pain and eventual death. This can occur when an animal tries to ingest the lantern, or when lanterns that have landed on farmland are accidentally harvested along with crops, causing metal fragments to be incorporated into animal feed.

Secondly, sky lanterns can take a long time to decompose, with some parts taking over a year to biodegrade. This means that they can sit on land for an extended period, posing a threat to wildlife and the environment. The wire frames, for example, can take nine months, on average, to break down, and during this time, they can strangle and maim wild animals and livestock.

Thirdly, sky lanterns pose a significant fire hazard. They have been known to cause wildfires and structure fires, including a massive fire at the Smethwick Recycling Plant in England and a fire that killed 50 animals in the Krefeld Zoo in Germany. The risk of fire is heightened by the fact that the lanterns are often released into the sky with an open flame, which is uncontrolled and can ignite surrounding vegetation or structures when the lantern descends.

Overall, while sky lanterns may be a beloved tradition in many cultures, their potential harm to wildlife and the environment cannot be overlooked. It is essential to consider alternative ways to celebrate and commemorate that do not pose such risks.

Lanterns can cause fires

Sky lanterns are a well-loved tradition in multiple cultures, often used to celebrate holidays, make wishes, or mourn the passing of a loved one. They are made of paper, cloth, string, and wire or bamboo for support. They are also fitted with a candle or fuel cell that, when lit, causes them to rise into the air.

However, sky lanterns pose a significant fire hazard. Lanterns with an open flame can start fires when they come down, igniting dry vegetation or buildings. Sky lanterns have caused multiple wildfires and structure fires, including a massive fire at the Smethwick Recycling Plant in England and a fire that killed 50 animals in the Krefeld Zoo in Germany. In Thailand, local authorities have begun banning the sale of sky lanterns, and in Germany, three states have banned them following the death of a child in a house fire caused by a lantern. Sky lanterns have also caused nearly 20 forest fires in Vietnam, prompting a nationwide ban.

Even biodegradable lanterns can pose a fire risk. While the paper may biodegrade within a few days to a few weeks, the wire frames can take nine months or more to break down. During this time, they can entangle and maim wild animals and livestock, and the wires can damage the throats and intestines of animals that ingest them.

To reduce the fire risk, some lantern festivals use LED candles instead of real flames. Others work with manufacturers to reduce the flight distance of lanterns, ensuring they are extinguished before landing. However, even with these measures, sky lanterns remain controversial due to their potential environmental and safety hazards.

Lanterns are made from non-biodegradable materials

Sky lanterns are made from a variety of materials, including paper, bamboo, wire, and other non-biodegradable substances. While some sources claim that the paper in these lanterns is biodegradable, it can still take several weeks to break down, and the remaining components can take much longer. For example, a sales representative from a UK sky lantern retailer claimed that the paper in their lanterns biodegrades within "six to eight weeks," but the "flourished wire" takes nine months, on average, to break down. This means that even if the paper in a lantern biodegrades relatively quickly, the wire frame can still pose a risk to wildlife and the environment in the meantime.

The wire frames of sky lanterns have been known to strangle and maim wild animals, livestock, and domestic animals. They can also cause internal damage if ingested, leading to immense pain and even death. This is a significant concern, as animals may mistake the paper or other components of the lanterns for food. Even if the wire frame does eventually biodegrade, it can still take a long time, during which it can cause harm to the environment and wildlife.

In addition to the wire frames, other non-biodegradable materials used in sky lanterns can also pose a risk. For example, some lanterns use cardboard and wax fuel cells, which allow them to float when lit. These fuel cells, along with other non-biodegradable components, can contribute to litter and pollution when the lanterns come back down to the ground. This litter can be washed into lakes and rivers, further harming the environment.

The potential harm caused by non-biodegradable sky lantern materials has led to concerns and bans in several countries and states. For example, the Vietnamese prime minister announced a sky lantern ban in 2020 due to the risk of forest fires. Germany, Thailand, and the UK have also seen bans or increased restrictions on the sale and use of sky lanterns due to safety and environmental concerns.

While sky lanterns may be made with biodegradable materials like paper and wood, it's important to consider the presence of non-biodegradable substances as well. The wire frames and other components can take a long time to break down, during which they pose a significant risk to wildlife, livestock, and the environment. As a result, it's crucial to carefully consider the potential consequences of releasing sky lanterns and to prioritize sustainable and eco-friendly alternatives whenever possible.

Some lantern festivals have an in-depth clean-up process

Sky lantern festivals are undoubtedly a beautiful sight to behold, but they can also be harmful to the environment and wildlife. Lanterns are made of materials such as paper, bamboo, string, and wire, which can take a long time to decompose, posing a threat to animals and the environment. The wire frames, for example, can strangle and maim animals, and the ingestion of wires and paper can damage the throats, stomachs, and intestines of livestock and wildlife, leading to immense pain and even death.

However, some lantern festivals have implemented measures to mitigate these environmental concerns. The Water Lantern Festival, for instance, prioritises sustainability and leaving no trace. They employ an in-depth clean-up process to retrieve every lantern and any existing trash from the water after each event. Their lanterns are also crafted from sustainable materials, such as rice paper and wooden bases, and they encourage the reuse and recycling of LED candles.

The Rise Festival in Las Vegas takes a different approach by holding the event in a designated zone in the desert, making it easier to clean up afterward. Some lantern festivals, such as the one organised by Dane Cannon, use biodegradable lanterns and rely on volunteers to pick up the lanterns after the event.

While these efforts are commendable, it is important to recognise that even biodegradable lanterns can take a significant amount of time to break down. The wire components, in particular, can take up to nine months or more to degrade, and the paper can take six to eight weeks, which is still a substantial amount of time for debris to remain in the environment.

Overall, while some lantern festivals are taking steps towards sustainability and clean-up, the potential environmental and ecological impacts of sky lanterns cannot be overlooked.
