"The human footprint on the earth has grown explosively over the past
century or two. Two hundred years ago, there were about 1 billion of us;
today, we number more than 7 billion. We have harnessed vast amounts of
energy, cleared countless forests, dammed thousands of rivers,
reconfigured entire coastlines and built vast cities. We appropriate
about half the planet’s accessible fresh water and nearly half the
desert-free land surface to feed ourselves."
Systems thinking. Via Tam McDonnagh and Cindy Brown.
