A future map is like a picture of what the world might look like in the future. Just like how you can draw a picture of a person, a future map can show us what the world might be like in 10 years or 100 years.
Some people like to make future maps because they want to imagine what the world might look like if certain things happen. For example, if we keep polluting the Earth, the future map might show more pollution and less clean air. Or if we invent new technology, the future map might show us flying cars or robots doing our jobs.
Future maps can be really helpful because they show us what might happen if we don't change the way we do things. If we see a future map with a lot of pollution, it might encourage us to make changes to reduce pollution now.
But it's important to remember that future maps are just pictures of what might happen. They can't predict the future for sure, and we can always make changes now to create a different future.
