How Does Limestone Affect the Environment?

2020-4-9  While limestone itself doesn't affect the environment, limestone mining can have a negative impact. On the other hand, the environment can affect limestone by breaking it down. Limestone mining can pollute water and create sinkholes. When limestone dissolves while it's still in the ground, caves and gullies form, a natural phenomenon known as karst.
