Do we have so many of them that we are running out of dumping grounds? Are they made of rare, hard-to-obtain stuff? Are they toxic or otherwise dangerous?

(For hundreds of millions of years, mollusks did not recycle their calcite shells. It had major ecological and even geological consequences. Now we have literal mountains of them. Has even it made Earth a worse place? Some old blades are nothing in comparison.)
