According to scientists at the UK's Royal Society, Watching a television show in standard definition can shave a little off your carbon emissions.

About eight times more emissions are said to be generated from 4K video streaming (Also known as Ultra HD) on a phone than standard definition(SD). The viewer rarely sees any difference between the 4K and SD on a small screen.

The scientists' report says digital technology’s estimated contribution to global emissions ranges from 1.4% to 5.9% of the global total.

Also turning off any accompanying video if people are just listening, not watching can be another way to save energy. Even such small moves are said to save up to 5% of the emissions from a streaming service.

Changing the phones after their wise usage can also help save energy. As during the manufacturing of phones, it emits about half of the emissions it will emit through its lifetime. A report says buying a device second-hand - or sharing equipment - also reduces the share of so-called "embodied emissions".

Also, Using the cloud rather than computing from home or business desktops can help save energy, for the cloud partners are more efficient for server use.

Digital revolution should take place supporting climate revolution.

Are smartwatches safe? That’s one of the biggest concerns about people about to buy smartwatches. Here are some points that will resolve your curiosity.

 

How does a smartwatch work?

Unironically, smartwatches are small computers that you can wear on your wrist.

Through syncing with a smartphone and linking to an Android Operating System or iOS from Apple, they operate. Most of them will connect to the internet and pair with smartphones that are Bluetooth-enabled.

Privacy concerns

Smartwatches use wireless networks to transmit information to different devices, This feature is a matter of concern because it might not be as secure for the protection of data transmitted from a smartwatch to a phone. For individuals who use smartwatches to pay digitally, this is highly disturbing.

For one by intercepting the signal, then stealing data, hackers might get your personal information, particularly if it is not encrypted.

Can Smartwatch cause cancer?

That has yet to be proven. While there are studies that indicate radio frequency is a carcinogen, smartwatches themselves have not been linked to cancer.

Do they emit radiation all the time?

As long as they are synced with a smartphone, then yes. However, if the watch is in airplane mode, it won’t emit radiation.

So what can we do about smartwatch radiation?

• Switching your smartwatch to airplane mode is another option, which disables wireless communications such as WiFi, Bluetooth, and cellular data. And in airplane mode, music and more can be downloaded in full, then enjoyed.
• Don’t wear it when you sleep.

Conclusion” Are smartwatches safe?”

There is no definitive answer, as of now, as to whether or not smartwatches are secure. Some scholars, on the one hand, say there is little to think about. However several experiments have been performed on electromagnetic and radiofrequency radiation that have indicated a negative impact.
