Global surveillance means that people in charge are listening in and watching everything that people do around the world. It's like a big group of grown-ups who are always watching to make sure everyone behaves properly. This is done using different methods such as cameras, recordings, and spying software.
Sometimes, the people who are being watched might not even know it is happening. For example, if someone sends a text message or an email, it might get recorded without them realizing it.
Now, let's talk about journalism. Journalists are like detectives who find out what is happening in the world and tell other people about it. They go to different places to find out what's going on and then write or report on it.
But sometimes, journalists can't always get the whole story because the people they talk to might be scared or not want to share everything they know. This is where global surveillance comes in. Sometimes, journalists use the information that is collected through surveillance to get a better understanding of what is happening.
However, there is a big debate on whether global surveillance is right or not. Some people think that it's necessary for safety, while others think it's an invasion of people's privacy. Journalists also have a responsibility to be careful with the information they use from global surveillance and make sure it's not used to harm anyone.
So, in summary, global surveillance is when people in charge are always watching what everyone is doing around the world, and journalists sometimes use this information to help them tell stories better.
