% O: f* r* p* mAccording to this article, in 2016, light pollution block the Milky Way galaxy in the night sky for more than 1/3 of the world. Also, more than 99% of Americans live under light-polluted skies, and some spots in the USA may never again experience a true night. In the Study, scientists used low-light imaging from a NASA satellite and combined it with data collected from over 30,000 sky brightness monitors to map out levels of light pollution. Then, scientists found Singapore, Kuwait, South Korea, Canada, Spain and USA’s east coast experience some of the world’s worst light pollution. Excess light pollution affects humans' circadian rhythms and environment. However, Excess light pollution could be reduced by shielding or limiting the amount of artificial illumination. Installing new infrastructure that does not allow light to escape into the atmosphere would help alleviate the problem. Using LED light with warmer color spectrums instead of blue ones could also decrease light pollution. In the final of article, the author said "In our urban centers, you’ve got multiple generations of people that could not go out and see the Milky Way, and it’s a shame that they can’t,” ' P/ I Y9 o O4 r# c
