By switching to outdoor LEDs to lit surface of Earth at night, increases light pollution.
A new study shows that the use of LEDs across the globe is increasing the ‘loss of night’ and that the artificially lit area on Earth continues to grow
The research published in Scientific Advances shows that now we are being suffocate in worst light pollution, than ever before.

This nighttime look at our home planet, dubbed the Black Marble, provides researchers with a unique perspective of human activities around the globe. By studying Earth at night, researchers can investigate how cities expand, monitor light intensity to estimate energy use and economic activity, and aid in disaster response.
