light pollution

 Rest easy, trees

Students at Wakefield Elementary are on a mission to save the planet, and recently, they’ve scored a major win for the environment.   

On Jan. 27, school principal Julie Greig shared some exciting news with members of The Green Project, a group of students in Grades 4, 5, and 6 who meet weekly to discuss ways to help the environment: The Green Project’s efforts to get one of the school’s outdoor lights turned off at night had been successful. The Low Down was on hand during the announcement and heard the loud roar of the students’ cheers as they heard the news. 

The group’s campaign to get an outdoor light turned off at the school started last year after students were studying the growth of the micro-forest of young, indigenous treesthey had planted next to the building in 2019. Rosemary Millar-Bunch was a Grade 1 student at the time and took part in planting some of the trees with the rest of her class. A few years later, Rosie, as she’s known to her friends, became worried about those trees after she realized that a bright flood light was always shining directly on them at night, meaning that the trees never got to experience darkness. She had learned from her grandmother, Noelle Walsh, that trees need darkness at night the same way humans do: it helps regulate their growth cycles by allowing them to regenerate a key compound known as phytochrome. According to the Astronomical Society of Canada, without darkness, a tree can fail to thrive.  

Rosie decided to do something about it. Last year, when she was in Grade 4, she wrote to her principal explaining her concern and requesting that the light be turned off at night. She was initially told that, for security reasons, it wouldn’t be possible. But Rosie remained determined. This fall, Rosie approached the other members of The Green Project about her concerns and showed them another letter she had drafted, this time citing research she had done online. The rest of the group helped her refine the letter, and everyone signed it. The letter was delivered to principal Greig, adorned with a total of 13 student signatures.

Principal Greig took the letter to the Western Quebec School Board, which agreed that the light could either be redirected away from the trees or turned off entirely. 

In a unanimous vote, the students decided the light should be turned off entirely at night to protect the trees. 

“I am so very proud of the initiative of this group of students,” Greig told the Low Down. “They saw a problem with constant light over the micro-forest, did their research, [and] wrote a professional letter…They have learned how to be advocates for the environment.”

“This is a sign that we can act and do something,” Rosie told the Low Down. “It’s possible that we, young people, can make a real change.” 

The Green Project members now have their sights set on more advocacy work. They want to educate other students about caring for trees on the school property and they also want to put out a wider call to the community to “step up,” as one student put it. 

“Wakefield is a small community, and we are all good friends,” Grade 6 student Alyssa Carle told the Low Down. 

“We have all got to figure out how to work together to make it a better place. The Green Project gives me hope.” The students are also working with Wakefield artist cj fleury to decorate a chair that will be installed in the La Pêche municipal chambers to represent the youth voice on issues relating to the environment. 

La Pêche mayor Guillaume Lamoureux, who visited The Green Project during their weekly meeting on Feb. 3, proposed the idea of the chair based on a similar installation known as the “Chair of the Generations” inside Gatineau City Hall.

St. Laurent council passes bylaw to reduce light pollution

St. Laurent council passed a bylaw — a first for Montreal —at its Oct. 1 council meeting to reduce light pollution on some categories of private property, to enable residents to see a “starrier sky” at night.

A borough statement points out that the measure is aimed at “industrial, commercial and institutional establishments” and the goal is to “better protect the territory’s ecosystems and biodiversity, increase road safety, promote public health and improve energy efficiency.”

Mayor Alan DeSousa said, with some humour, that “this is an initiative that goes to the heart of sustainable development, since it not only protects biodiversity, but also increases road safety and improves the health and quality of life of St. Laurent residents and workers on our territory. I dare say that our administration is very bright and that council is making enlightened decisions!”

The borough statement explains that light pollution “refers to the excessive or inappropriate use of artificial light. Light pollution is particularly prevalent in St. Laurent, since 70 percent of its territory is devoted to industrial and commercial activities and it is situated next to the Montréal-Trudeau international airport and several highways, including the CN rail yard.”

The explanation adds that light pollution can affect quality of life and the environment.

“Already known for its impact on the night sky, it also has harmful effects on biodiversity and ecosystems, by altering the interactions between plants and pollinators or between prey and predators, hindering foraging, reproduction or migration. The glare it generates also has a negative impact on the safety of pedestrians and motorists. In addition, light pollution wastes energy and therefore increases the production of greenhouse gases. Last but not least, it poses a risk to human health by upsetting the body’s biological clock.”

The new bylaw “aims to control and limit light pollution on private property, without compromising the safety and comfort provided by lighting and taking into account the specific characteristics of the territory.

“It covers four areas of intervention: colour, orientation, period and quantity of light, according to the following principles: Define situations that allow the use of bluish light. Direct light flows towards the ground. Reduce certain lighting devices after 11 p.m. Set maximum light levels according to land use.”

The categories of buildings affected are “industrial, commercial and service buildings; multi-family dwellings, multi-family service dwellings and multi-bedroom dwellings, “with provisions applicable to building lighting, outdoor parking spaces, signs and billboards.

“Light flows must be directed towards the ground and the colour of light sources must be limited. In addition, aside from certain exceptions, lighting intensity must be reduced between 11 p.m. and 6 a.m. Similarly, curtains are required for greenhouses on industrial roofs with lighting systems.”

There are exemptions to the bylaw, including single-family and two-family homes and multiplexes “and certain types of equipment, such as light fixtures with motion detectors, or temporary outdoor lighting for special activities: outdoor shows, festivities organized by the borough, construction areas or other temporary work projects. Other exemptions are established for outdoor lighting related to public safety or for enhancing a heritage building.” n
