    There's one thing I've often wondered about reading about CO2 levels. Apart from climate change, scientists worry about acidification of the oceans and its effect on the micro-fauna. Apparently, if the seas become too acidic they cannot form their shells. This does not make sense to me because CO2 levels were much higher in the past and those tiny sea creatures existed then, didn't they?

    We have killed 1/3 of all living creatures in the sea. That has to have an effect too. Along with deforrestaion causing more nutrients to flow into the rivers and sea. Chemical pollution, oil spills and extra CO2 to absorb...

    Would be surprised if the seas stayed chemically the same. My bet is they will return to a primitive soup like when earth was young.
