The United Nations Ocean Conference is like a big meeting where lots of people from different countries get together to talk about the ocean. The ocean is a big, big body of water on Earth, and lots of animals like fish and whales live in it. But sometimes people do things that hurt the ocean, like throwing trash in it or catching too many fish, and that makes the animals and the ocean sick.
So the people at the UN Ocean Conference talk about ways to make the ocean healthy again. They talk about how to stop throwing trash in the ocean, how to catch fish in a way that doesn't hurt the ocean, and how to make sure the animals in the ocean have a safe and happy home. They also talk about how different countries can work together to take care of the ocean, because the ocean is important for everyone on Earth.
There are a lot of things people can do to help the ocean, like not using too much plastic, not driving cars too much, and using clean energy like solar power. The people at the UN Ocean Conference talk about all these things and more, to help make the ocean a better place for the animals and for people too.
