The resources in the resource mining area in "Frost Age 2" are basically limited. After the resources are mined, they will no longer be produced, and the supply of certain resources in New London will be cut off. If you want to ensure the supply If a replacement is required, you should ensure that the replacement area is constructed and put into use before the original area is closed.
How to change the resource mining area in Ice Age 2
The game gives you ample warning when an extraction zone starts to run low on resources, and you'll see a depletion meter appear. It's time to start looking for new sources of the resources produced by the area - once the resources are depleted, the area will need to be dismantled as it will no longer serve any purpose.
You should ensure that a replacement zone is built and in use before the original zone is closed - ideally, it has the same capacity as the original zone. This ensures that the city's production is not interrupted and may even have extra output during this period to add to your reserves.
If you wait until the resource is completely exhausted before building new areas to produce it, you are waiting too long.
