The Anthropocene

"How many wolves live today in Germany, the land of the Grimm brothers, Little Red Riding Hood and the Big Bad Wolf?  Less than a hundred.  (And even these are mostly Polish wolves that stole over the border in recent years.)  In contrast, Germany is home to 5 million domesticated dogs. Altogether about 200,000 wild wolves still roam over the earth, but there are more than 400 million domesticated dogs.  The world contains 40,000 lions compared with 600 million house cats; 900,000 African buffalo versus 1.5 million domesticated cows; 50 million penguins and 20 billion chickens.  Since 1970, despite growing ecological awareness, wildlife populations have halved (not that they were prospering in 1970).  In 1980 there were 2 billion wild birds in Europe.  In 2009 only 1.6 billion were left.  In the same year, Europeans raised 1.9 billion chickens for meat and eggs.  At present, more than 90 percent of the large animals of the world (i.e., those weighing more than a few kilograms) are either humans or domesticated animals."
