Life makes Life

Awhile back I read a fascinating book called Becoming Earth [1]. Conventional
wisdom has it that our planet evolved through geological means until it was
suitable for life. The theory presented in this book is that it was life
itself that brought about the geological changes needed for life to thrive
and evolve. For example before our atmosphere contained enough oxygen for air
breathing life to evolve, more primitive life forms evolved to add oxygen to
the atmosphere.
>Life and its environment have coevolved for billions of years, transforming
>a lump of orbiting rock into the cosmic oasis we call home. Life breathed
>oxygen into the atmosphere, dyed the sky blue, concocted the modern oceans,
>and converted barren crust into fertile soil.
>
It's a fascinating book and I encourage everyone to read it.
Now comes news of a recent discovery [2] that certain fungi, using DNA that
they appropriated from bacteria, can seed clouds and create rain. Basically
the soil itself influencing the sky to send it some rain.
Many years ago while walking through a Redwood forest in central California I
had an illuminating experience I will never forget. It was drizzling rain.
The ground was covered with moss and ferns and all the kinds of things that
only grow and a cool wet environment. But then I came to a clearing and
walked out into the dry sunshine. It was a clear day, not a cloud in the sky.
Looking back at the forest I could see that it was holding in it's own fog
like moisture layer. A few years later I moved to the Oregon Coast where I
witnessed huge swaths of clearcuts. I could see the rain clouds coming in
from the ocean would pass right over the clearcuts until they hit a standing
forest which slowed them down so they could dump their rain. Years before
climate change was a well understood phenomenon I could see how clearcut
logging was upsetting the coastal environment.
Planet Earth is one big interconnected organism. Our survival as a species
depends on our ability to understand and work with the natural systems that
makes life possible.
