Okay, let's talk about something called the "Campaign for Nuclear Disarmament" or CND for short.
Basically, some people think that having really big and powerful bombs like nuclear weapons is a bad idea. They worry that if countries keep making and having these bombs, then everyone could be in danger of a big explosion that could hurt a lot of people and make a big mess.
So, the Campaign for Nuclear Disarmament is a group of people who are working together to try to get people to stop using and making these big bombs. They want to get rid of all the nuclear weapons in the world.
They think that if there are no more nuclear bombs, then everyone will be safer and happier. They think that countries can still protect themselves without having these big, dangerous weapons.
The Campaign for Nuclear Disarmament people want the governments around the world to agree to stop making and using these bombs. They want them to talk and find other ways to keep people safe without using nuclear weapons.
So, they organize rallies and events to get people to pay attention to this important issue. They try to convince others that having nuclear weapons is a bad idea and that we should all work together to get rid of them.
Overall, the Campaign for Nuclear Disarmament is a group of people who want to help make the world a safer place by getting rid of dangerous nuclear weapons.
