"Baked in" change

I can see you fishing on the reef where my house used to be. But I can't see whether you fish for pleasure or in desperation for protein. Is the dissolving concrete from our buildings balancing the acid rain to make a northern haven for coral? When you sail home, will it be to a life something like mine, or to a spoiled and bitter wasteland? Then I remember that the answers lie here, not in your time.
