Someone a few years (10) ago gave us an old refrig that
we use as 2nd refrig.

That bottom drawer -- slides out -- stationary shelf that
it slides in and out under is clear plastic (other shelves
are made of matrix of metal rods) are of course strong,
not likely to ever break or even bend.

But this bottom (cheap) plastic shelf is cracked and
bending down in the middle.

What can I do to fix it before it completely fails?

What, try to find another piece of hard plastic to
bond to it? Where would I find that?

Ten years ago you were given a use refrigerator so now it is 15 to 20 years
old and yet you call the broken part "cheap plastic"

Try supporting the middle if you can. You can try epoxy, but not much of
anything sticks to the plastics generally used inside of appliances. You
may have better luck with a mechanical fastener.
