Default The Anthropocene is here!

I was reading an interesting article today about how our current geologic era should be termed the Antropocene - since the human population has become the primary factor in the ecology and geochemistry of life on earth, and totally dominates the biosphere. There was one little factoid I found really astonishing.

In 2013, the total dry weight biomass of the 7+ billion humans on earth is 125 million tons.
The total dry weight biomass of all our domestic animals is 300 million tons.

The total dry weight biomass of EVERY OTHER TERRESTRIAL VERTEBRATE ON THE PLANET is 10 million tons.

I found that really hard to believe, so I looked up the citation - it's from MIT and was published in a peer-reviewed journal, so I think we can assume they got the math right.

I thought it seemed a little crowded around here.....

Scientists say that about 15 percent of the Earth's total biomass _ the
combined weight of all living things _ is composed of ants. Another 17
percent is taken up by termites. The combined weight of all ants on
earth is more than the weight of all humans.

yeah I was going to say that

How is this possible? This would mean each human has about 3 domestic animals on average.

I think that study just refers to the stick figures on the back of mini vans

The combined weight of all ants on earth is more than the weight of all humans.

Aha! So ants are causing the climate change.
