It's not easy to seal a pond in some soil conditions. Sure, you could gley it if you had the time and livestock. Not everyone has this option.
I personally believe that any environmental cost of using a pond liner will be repaid 100x over in supporting the living landscape. In my experience, it's literally an oasis. Birds, bees, pollinators -- all of these will seek out your reliable source of water, set up shop, and thrive.
