Geo-wiki is like a game that helps us learn more about our planet. It's a special website where people from all over the world can play together and help make maps.
The maps show things like where there are trees, what the weather is like, and how many animals there are in different parts of the world. The maps also show where there are problems like pollution, droughts, and wildfires.
When you play Geo-wiki, you look at pictures of different places on Earth and answer questions about what you see. For example, you might be asked if there are any trees in the picture or if the land looks like it's been farmed.
The answers you give help scientists and people who study our planet better understand what's happening in different parts of the world. This knowledge can help us protect Earth and all the living things on it.
