The chalk cliffs of the Baltic island of #Rügen's Jasmund peninsula are ancient. I took this pic last week.

They're made of the microscopic remnants of tiny organisms that thrived in the light-flooded shallow seas of the late Cretaceous, 70 million years ago.

We humans, homo sapiens, arrived a mere 300.000 years ago. We're but a speck in time.

It's up to us, whether we overwhelm our planet's ecological heritage with our greed. And whether we spend our time with compassion and empathy.
