Global 200 is a list of the most important places in the world for plants and animals to live. It's like a big map of all the places that are super special and need to be protected.
Scientists looked at things like how many different kinds of animals and plants live in each place, and how important those animals and plants are to the overall variety of life on Earth. They then picked the top 200 spots that were the most important to protect, and put them on this special list.
By protecting these places, we can make sure that all the different types of animals and plants that live there are safe and can keep growing and living happily. It's kind of like a big playground for all the living things on Earth and we want to make sure everyone has a chance to play and thrive.
