luckily volcanoes still exist

We're sure very actively trying to destroy ourselves via economic growth, industrial evolution, globalisation, preventive wars, oil rigging, mining, buy&throw-away habits, linear cradle to grave production.
But we can thank nature for having thought of how to cope with our attempts to destroy its wonders. Plate tectonics will save Earth from us, as it saved it from previous settlers, sometimes with a little hand from outer space friends too.
It may get a bit hectic, but floods, tsunamis and large eruptions will settle things down. Some sort of life will surely survive. It's refreshing to think that there will be life after us.
