Why would lakes and ponds disappear if permafrost thaws?

When permafrost thaws, it can lead to the drainage of lakes and ponds because the ground, previously frozen, becomes more permeable. This allows water to seep into the ground, reducing the volume of surface water. Additionally, the thawing can alter the landscape, creating new drainage patterns that may lead to the disappearance of existing bodies of water. The combination of these factors can significantly impact local ecosystems and hydrology.
