LANSING — Americans celebrate holidays by sending things up.
But popular Chinese sky lanterns can kill livestock, strangle wildlife and cause fires, experts say.
Sky lanterns are made of paper, cloth and string. They use wires or bamboo for support. So-called fuel cells made of cardboard and wax allow them to float when lit.
They can soar more than a thousand feet and travel for more than a mile, depending on winds.
And that makes them dangerous, said Rep. Henry Yanez, D-Sterling Heights.
Yanez, a former firefighter, has proposed legislation to roll back the state’s fireworks law and prohibit the lanterns. They already are illegal in 29 states, including Minnesota, Illinois, Indiana and Ohio.
Cosponsors include Democratic Reps. Andy Shor (D-Lansing) and David LaGrand (D-Grand Rapids).
Citizen worries over fire hazards prompted the so-far-unsuccessful try at a ban, Yanez said.
“We heard from many of them that the sky lanterns were an issue too, and people were sending us news articles of fires that were suspected to be caused by sky lanterns,” he said.
“It could land on a tree, it could land on a home, it could land in grasslands or forests, and a fire could start.”
The lanterns often are part of celebrations and tributes, and are even more common around the Fourth of July. Although no major fires were reported this year, fire safety officials in many states issued warnings against using lanterns because of the risk of fire.
Light the Sky Grand Rapids recently held a lantern launch at the I-96 Speedway in Ionia County’s Lake Odessa.
More than 500 people bought tickets to launch lanterns to raise money for refugees, said Dane Cannon, who works for the company marketing the event.
His firm was being proactive, working with manufacturers to reduce the flight distance to three-quarters of a mile or less, depending on the winds, he said.
“It seems like as we’ve talked to fire officials who’ve held these events in their municipalities that their main concern is fires only on the way up, not necessarily on the way down, because on the way down, you know that the fire is already extinguished,” he said.
The company also used biodegradable lanterns. Cannon said he isn’t sure how long it takes them to biodegrade.
Many of the lanterns fell in nearby fields; workers were out the next afternoon retrieving them.
Patrolling farm fields for litter that could be a hazard to livestock is a daily chore for Amanda Powell, who runs Oak Row Angus Cattle in Ionia.
“They look nice going up, but when they come down they have an impact on the environment and animals,” she said. “We found one place where you could see it caught fire a little bit. It stopped, but it didn’t have to. If it had been a really dry year, it could have gone from there.”
Powell said she’s found lanterns with wires in pastures.
Such wire can sicken cattle with hardware disease, said Jennifer Roberts, a veterinarian with Michigan State University’s College of Veterinary Medicine.
And metal objects caught in harvesters and ground into feed can kill livestock, she said.
It’s difficult to trace metals back to a specific item because they often are ground into food. But the metal wires in lanterns pose an obvious risk, she said.
“The way that cows digest their feed is that it goes into their stomach and she re-chews it again later — she may not actually chew it and realize it’s something that she should not eat,” Roberts said.
Farmers often put magnets in cattle’s stomachs to prevent hardware disease, Roberts said. While lanterns made of biodegradable materials can likely be digested, no animal should eat trash.
“One big part of that is making sure that the feed is safe for them and isn’t going to make them sick,” she said.
A Facebook post by a dairy farmer in West Branch about a lantern containing floral wire found during harvesting received 22,000 shares last July.
The post by Abigail O’Farrell, co-owner of Lemajru Dairy Farm, said lanterns could kill her cows. It received thousands of comments. Some were critical.
“I have friends that I know have lit them off in the past year. And I know when it comes to memorials to tell someone it is a bad idea when they are trying to remember a loved one, you are dealing with emotions, and it isn’t the right time and right place,” O’Farrell said.
Other people opposed bans and commented that many things are dangerous to animals, and they can’t all be banned.
Even if people aren’t concerned about livestock, O’Farrell said she hopes they will use biodegradable lanterns and not light them during drought conditions or near dead trees.
Balloons Blow, a Florida-based environmental advocacy group, posts graphic images online of animals killed by lanterns and other floating objects. The group said even biodegradable lanterns threaten wildlife because animals get caught in the strings.
Some farm organizations also oppose lanterns.
Awareness is essential, said Ernie Birchmeier, the livestock and dairy specialist at the Michigan Farm Bureau.
“I don’t think people understand the consequences of sending something up in the air and realizing it has to come down, so there is an education process that needs to take place,” he said. “Whether it’s with wire or biodegradable, whatever it is made of, they are going to come down somewhere and it’s not on your property. It’s somebody else’s property, and there are negative impacts of that.”
The Michigan Farm Bureau supports a lantern ban.
Michigan, Wisconsin and Pennsylvania are among the Great Lakes states without a lantern law, but some local ordinances prohibit them.
Yanez, the state lawmaker, said a statewide ban in Michigan is unlikely, partly because his legislation is attached to restrictions on fireworks.
“People make a lot of money in a very short amount of time selling these fireworks,” he said.
Caution about where lanterns are launched is likely the only solution unless a large-scale incident spawns interest in the bill, he said.
