That's a lovely bit of rhetoric to appeal to the Greens. (I say rhetoric because if you are cremated, there's nothing to offer back, and if you are buried, you are usually embalmed and now 'the flora and fauna' will be poisoned if they try to take your offer anytime soon.) I wish I could manage that trick.
All the biological material will be cycled back into the ecosystem, most of it quite soon - even despite the presence of toxins (formaldehyde-eating bacteria, etc). His statement is correct in the sense that if you are cryopreserved, the net amount of carbon, nitrogen, phosphorus, etc in the biosphere will be slightly lower than it otherwise would have been.
Not attacking your position, just pointing that out.
