Our paper

The idea of our project was try to find a solution to reduce the light pollution, then we realize that the important part of the whole thing is to bring people to the attention. Maybe many people didn't even realize how big the impact of light pollution was.

It costs a lot of money to light up homes, public places, sports and commercial places. Apart from the fact that tax payers pay needlessly for this, the nation uses millions of tons of oil and coal to produce the power needed to light the sky. Meanwhile, the environmental cost of producing this energy is another worrying issue that can be discussed at another time. In the USA, 8% of its total energy is used for outdoor lighting, and out of that, 80% is used for commercial and public exterior lighting.

Disability glare, eye strain, loss of vision and stress that people get from glare and spillovers are worth mentioning. Our eyes naturally adjust during day and night so we can see things properly. Too much light can harm our eyes and also the harm the hormones (such as melatonin) that does this job.

Turtles many insects, birds, mammals and reptiles are photoperiodic in nature. Examples include sea turtles. Many aspects of their physiology and behavior are influenced by day–night or circadian rhythms. This means their eating, mating, growth and development, movement and other activities are in relation to the balance of day and night. Artificial lights, even in small amounts can distort their natural operations and cycle. Thousands of deer and animals are killed on the roads by vehicles in the evenings, because the glare of these cars blind them and are unable to run off the streets before they are knocked down.

In our video, we interviewed an expert through telephone, she also talked about how big the impact was. We also interviewed the mayor of Rosny-sous-bois, and we realized that there is room to improve in the policy side. And there is still a far distance to cause people’s attention to such an issue. We hope there will be organizations who step up to make some move. And the only thing we sure about is there is still a lot of work ahead.
