@Enyavar1 That's not really true though. Wood is still an afforable easily accessible resource. It's just far less efficient than steel is for making ships (and a lot of other things as well, wood is actually not that great from a pure material science perspective). It's more expensive and less effective (wooden ships have a lot more drag than steel ships, so it either costs a lot more fuel to get somewhere or you're going a lot slower). The prevalance of steel over wood really only happened after the invention of the bessemer process (which made steel significantly cheaper). Before that ships where made of wood, and forests where actually less in number and size at that time compared to the contemporary world. Brittania ruled the waves after all, despite the UK being famously laking in wooded land (forests in the UK are quite rare, it has been barren for literal millenia after most has been chopped down before even the Romans arrived in Britain). You don't actually need a lot of forest to make a ship. While I won't deny that pollution hasn't been a thing, forests are actually not really less in number than they were during Roman times (at least in Europe, we can't really say the same thing for South America for example), wood for building doesn't actually require that much land. Most forests were destroyed when humans started the practise of farming, because burning forests made for excelent farmland (and still is, most of the amazon that we are losing is not chopped for the wood, but burned for the farmland to grow crops). So a very large portion of human destruction of forested areas happened well before the roman times, and in the last century there actually have been fairly sizable efforts to reforest Europe and the amount of forested land has vastly increased, not decreased over the last century.
