What we leave

“yes, we’re currently warping the chemistry of the atmosphere and oceans violently, and in ways that have analogues in only a few terrifying chapters buried deep in Earth’s history. Each year we spew more than 100 times as much CO2 into the air as volcanoes do, and we’re currently overseeing the biggest disruption to the planet’s nitrogen cycle in 2.5 billion years. But despite this incredible effort, all is vanity. Very little of our handiwork will survive the obliteration of the ages. If 100 million years can easily wear the Himalayas flat, what chance will San Francisco or New York have?”1
