Light pollution is growing rapidly and in some places the number of stars visible to the naked eye in the night sky is being reduced by more than half in less than 20 years, according to a study released in the journal “Science”.

The researchers said the increase in light pollution that they found was much larger than that measured by satellite observations of Earth at night. For the study of the change in global sky brightness from artificial light, the researchers used stellar observations from 2011 to 2022 submitted by more than 51,000 “citizen scientists” around the world, mostly in the United States and Europe.

The change in the number of visible stars reported was equivalent to a 9.6 percent per year annual increase in sky brightness, averaged over the locations of the participants, the researchers said.

Over an 18-year period, given such star brightness change, a location with 250 visible stars would see that number reduced to 100, according to Agence France Press (AFP).

The study coincided with the replacement of many outdoor lights with light-emitting diodes (LEDs), but the researchers said the impact on skyglow from the transition is unclear, according to the researchers.

They also said the visibility of stars is deteriorating rapidly, despite (or perhaps because of) the introduction of LEDs in outdoor lighting applications.

Existing lighting policies are not preventing increases in skyglow, they confirmed.

From dangerous diet tips to disinformation, cyberbullying to hate speech, the glut of online content harmful to children grows every day. But several European countries have had enough and now want to limit minors' access to social media.

The European Union already has some of the world's most stringent digital rules to rein in Big Tech, with multiple probes ongoing into how platforms protect children -- or not, said AFP.

There are now demands for the EU to go further as a rising body of evidence shows the negative effects of social media on children's mental and physical health.

Backed by France and Spain, Greece has spearheaded a proposal for how the EU should limit children's use of online platforms as fears mount over their addictive nature.

They will present the plan on Friday to EU counterparts in Luxembourg "so that Europe can take the appropriate action as soon as possible", Greek Digital Minister Dimitris Papastergiou said.

The proposal includes setting an age of digital adulthood across the 27-country EU, meaning children will not be able to access social media without parental consent.

Since the proposal was published last month, other countries have expressed support including Cyprus and Denmark -- which takes over the rotating EU presidency in July.

Danish officials say the issue will be a priority during their six-month presidency.

France has led the way in cracking down on platforms, passing a 2023 law requiring them to obtain parental consent for users under the age of 15.

But the measure has not received the EU green light it needs to come into force.

France also gradually introduced requirements this year for all adult websites to have users confirm their age to prevent children accessing inadequate material-- with three major platforms going dark this week in anger over the move.

Also under pressure from the French government, TikTok on Sunday banned the "#SkinnyTok" hashtag, part of a trend promoting extreme thinness on the platform.

Real age verification

Greece says its aim is to protect children from the risks of excessive internet use.

The proposal does not say at what age digital adulthood should begin but Papastergiou said platforms should know users' real ages "so as not to serve inappropriate content to minors".

France, Greece and Spain expressed concern about the algorithmic design of digital platforms increasing children's exposure to addictive and harmful content -- with the risk of worsening anxiety, depression and self-esteem issues.

The proposal also blames excessive screen time at a young age for hindering the development of minors' critical and relationship skills.

They demand "an EU-wide application that supports parental control mechanisms, allows for proper age verification and limits the use of certain applications by minors".

The goal would be for devices such as smartphones to have in-built age verification.

The European Commission, the EU's digital watchdog, wants to launch an age-verification app next month, insisting it can be done without disclosing personal details.

The EU last month published draft guidelines for platforms to protect minors, to be finalized once a public consultation ends this month, including setting children's accounts to private by default, and making it easier to block and mute users.

Those guidelines are non-binding, but the bloc is clamping down in other ways.

EU investigations

It is currently investigating Meta's Facebook and Instagram, and TikTok under its mammoth content moderation law, the Digital Services Act (DSA), fearing the platforms are failing to do enough to prevent children accessing harmful content.

In the Meta probe, the EU fears the platform's age-verification tools may not be effective.

And last week, it launched an investigation into four platforms over suspicions they are failing to stop children accessing adult content.

Separately, the EU has been in long-running negotiations on a law to combat child sexual abuse material, but the proposal has been mired in uncertainty, with worries from some countries that it would allow authorities to access encrypted communications.

The legal proposal has pitted proponents of privacy against those working to protect children -- and despite repeated attempts, it has failed to get EU states' approval.
