The wholesale use of mines and particularly cluster munitions really did lasting damage in several countries post WW2. WW2 bombs went underground when they didn’t detonate and that offers some “protection”. We don’t do heavy carpet bombing like that anymore. Mines and cluster bombs remain on the surface. It’s going to be even worse because modern weapons use a lot of plastic to avoid being easily detected and more cheaply produced. And if the few video clips I’ve seen of Ukraine lately are any indication, the use of small cluster bomblets is rampant. They’re slightly larger than your palm, green, and plastic.

There’s going to be a lot of missing feet in the following years.

Edit: found out what is being used in Ukraine are called “butterfly mines”. . There are going to be multiple thousands of these laying around.
