Crazy numbers from #Anthropocene Earth:

Weight of all wild mammals on land: 22 million tons

Weight of all wild mammals in ocean: 40 million tons

Weight of all humans: 390 million tons

Weight of all land mammals domesticated by humans: 630 million tons.

Interesting to test some of figures as e.g. sperm whales alone should be 20m t not 7m t.

But overall ratios are impressive.
