Awareness, Photosynthesis, and History
Andy Revkin on our ability to notice big things:We’re hardly the first life form to become a planetary powerhouse. Blue-green algae profoundly changed the composition of the atmosphere, adding the oxygen that today’s life forms rely on. But, as far as we know, those microorganisms weren’t aware of that achievement. Through science, humans are slowing becoming aware of planet-scale changes to ecosystems and the atmosphere with potentially enormous and long-lasting implications for climate and biology.As far as we know.How awesome would it be if the algae was aware of the oxygen they produced and the potential changes it was making to their world, and somehow we unlocked the records they kept of their conversations about it? Ridiculously awesome. And equally sad.
