Did you know that stargazing can help reduce global warming?

Global warming, a global problem that humans have campaigned to reduce greenhouse gas emissions over the years. both energy saving reduces the use of plastic bags reduce oil consumption Air conditioning, recycling and many other ways. But did you know that “Looking at the stars can help reduce global warming” as well.

greenhouse gases Most of it is carbon dioxide. which are pollutants from the combustion of coal, natural gas, and petroleum that are produced to be used as energy in various forms in daily life And one of them is electric power. used as a light at night

Nowadays, Light is an indispensable necessity. We take advantage of the light To read books, work, provide safety for traveling at night, etc., but a small amount of light is used carelessly, such as turning on unnecessary bright lights. Having lights in areas that are not in use shining in all directions distracts the eyes and annoys others. Including countless lights that lit up the sky without anyone taking advantage of them. We call these redundant or inefficient light “lights”. “Light pollution”

Light pollution makes the night sky not as dark as it used to be The Milky Way stretches across the night sky filled with stars. constellation tales The myths and myths of the sky that have been handed down from generation to generation are gradually being erased as the light fills the sky every year. With the lights that illuminate the whole community, today we have to drive tens of kilometers away. in order to come back to see the stars in the sky again

If ever seen a satellite image of the earth at night You may have noticed the light gradually popping up in various spots around the world. On the one hand, it is the color and beauty that reflects the way of life of people in each area, but on the other hand, it is the light that is produced. and thrown into space for nothing The only remaining greenhouse gases are stored in the earth’s atmosphere.

Fortunately, #light pollution problems can be easily solved. And see results immediately. One way is to install a lamp. Helps to control the direction of the light to illuminate the area that needs to be used. Do not shine brightly into the sky or other unnecessary areas. and choosing a light with appropriate brightness Not too bright than necessary In addition to reducing glare reflected in the sky. It also saves on electricity bills due to reduced bulb wattage. and reduce the glare of the eyes of passers-by in that area as well

There is research published that If reducing light pollution from street lights in the United States It will be able to reduce electricity costs by more than 9 billion baht and reduce carbon dioxide by as much as 21 million tons per year.

Working together to reduce light pollution It will help the night sky to see the stars again. and also encourages efficient use of lighting Reduce excess electricity production It also helps the world reduce greenhouse gases that indirectly cause global warming.
