The Human Age by Diane Ackerman. In
the year 1000 C.E., we humans and our domestic animals were only 2 percent of
the mammal biomass on Earth. We are now 90 percent of all the mammal biomass on
Earth. And we have inhabited or otherwise altered 75 percent of the Earth's
land surface.
From DelanceyPlace.com: Humans have always been hopped-up, restless,
busy bodies. During the past 11,700
years, a mere blink of time since the glaciers retreated at the end of the last
ice age, we invented the pearls of Agriculture, Writing, and Science. We
traveled in all directions, followed the long hands of rivers, crossed snow
kingdoms, scaled dizzying clefts and gorges, treked to remote islands and the
poles, plunged to ocean depths haunted by fish lit like luminarias and jellies
with golden eyes. Under a worship of stars, we trimmed fires and strung
lanterns all across the darkness.
We
framed Oz-like cities, voyaged off our home planet, and golfed on the moon. We
dreamt up a wizardry of industrial and medical marvels. We may not have
shuffled the continents, but we've erased and redrawn their outlines with
cities, agriculture, and climate change. We've blocked and rerouted rivers,
depositing thick sediments of new land. We've leveled forests, scraped and
paved the earth. We've subdued 75 percent of the land surface -- preserving
some pockets as 'wilderness,' denaturing vast tracts for our businesses and
homes, and homogenizing a third of the world's ice-free land through farming.
