Today in class we talked about more of the local and global scales. Local and global scales are important for geographers and for people who use maps. When geographers are deciding on how late of a scale to chose they first have to see what the issue or topic is. If it's a more local issue then the map could be of just a city. If it is more of a larger issue than the map could be as large as the earth. Like if you we trying to pick a map to help show how much carbon dioxide the world is producing than you would pick a map of the whole world. If you wanted to just talk about how many trees are in your hometown then you would pick a map of just your county
