Scientists warn that, in 20 years time, humans may not be able to see a starry sky at night at all due to increasing light pollution.

British astronomer Martin Rees, while talking with The Guardian, said that light pollution conditions have "rapidly worsened" over the past few years, quite significantly since 2016 when astronomers reported that the Milky Way was no longer visible to a third of humanity.

According to Rees, the increasing use of light-emitting diodes (LED) and other forms of lighting is "brightening the night sky at a dramatic rate".

Rees said: "The night sky is part of our environment and it would be a major deprivation if the next generation never got to see it, just as it would be if they never saw a bird's nest."

He added: "You don't need to be an astronomer to care about this. I am not an ornithologist but if there were no songbirds in my garden, I'd feel impoverished."

In another citing, Christopher Kyba from the German Centre for Geosciences, said: "A child who is born in a place where 250 stars are currently visible in the night sky would be able to see only 100 by the time they reach the age of 18."

british khagolashastri martin ris ne da gargian ke saath baat karte hue kaha ki pichley kuch varshon main prakaash pradooshan kii sthiti "teji se kharaab" hui he, 2016 ke baad se kaaphi kaaphi jab khagolavidon ne bataaya ki milky ve ab maanavtaa ke ek tihaai ke liye dikhaai nahin de rahaa tha.

ris ke anusaar, prakaash utsarjak diod (elidi) or prakaash ke anya roopon kaa badhata upyog "naatakeey dar par raat ke akaash ko roshan karnaa" he.

ris ne kaha: "raat kaa akaash hamaare paryaavaran kaa hissaa he or yah ek badi kami hogi yadi agali peedi ko ise dekhne ke liye kabhi nahin mila, thik usee tarah jaise ki agar ve kabhi kisi pakshi ke ghonsle ko nahin dekhte hai."

vaigyanikon ne chetavanee di he ki agar ham 20 varshon main prakaash pradooshan ko kam nahin karte hai, to log raat main sitaron ko nahin dekh paaenge.maanav nirmit prakaash kii maatra bad rahi he or jaldi se raat ke akaash ko roshan kar rahi he taaki log kam sitaron ko dekh saken.2016 main, visheshgyon ne bataaya ki prithvi par ek tihaai log ab milky ve nahin dekh sakate hai.yah tab se keval badtar ho gaya he.

vaigyanikon ke anusaar, elidi roshni akaash ko roshan kar rahi he.yah dukhad hoga agar agali peedi ke logon ko raat ke akaash main sitaron ko dekhne ko nahin mila.yadi yah jari rahata he, to ek baccha jo 250 sitaron ko dekh saktaa he jab ve paidaa hote hai to keval 18 saal ke hone tak 100 ko dekh paaenge.
