Personally I would far rather we find a way to live
within nature, co-existing within the limits of the natural world. Not because we can't yet recreate it as some Natureland theme park but because it is the right - and sane - thing to do. It doesn't mean accepting a primitive or non-technological life.
We can't guarantee we will ever be able to even know what we lost, let alone recreate what we're losing, or ever properly understand the interaction between species, or understand what discoveries we missed out on. Apart from anything else dramatically more species are undiscovered than discovered. Of those discovered vanishingly few outside the small number of agricultural ones are well understood. Agriculture that aims to remove species variation and variety.
Maybe I read too much into it, but with "I suppose" you make it sound as though you have a grudging acceptance to care only until such time as that magic Deus ex Machina of Jurassic Park and terraforming arrives. Then what? Right back to "fuck the environment we can terraform a new one"? Given human nature, far more likely we damage the natural environment way beyond our ability to either fix or live with and crash civilisation long before then -- damage without any care is a road we are very well travelled along after all. Seems "we" not including me have decided the planet's environment is secondary to profit. ...repeat until the profit or life support capability breaks.
