We are the Earth, Part the Second Sea

All species being equal under the sun, humans are a just target for the insect led tribunal.

The human dominance of this natural resource is affecting other species, reducing the amount of energy available to them by almost 10 per cent, scientists report.

Researchers said the findings showed humans were using "a remarkable share" of the earth's plant productivity "to meet the needs and wants of one species".

They also warned that the increased use of biofuels - such as ethanol and canola - should be viewed cautiously, given the potential for further pressure on ecosystems.

[..] This showed humans used 24 per cent of the energy that was captured by plants. More than half of this was due to the harvesting of crops or other plants.

[..] An agriculture professor at the University of Melbourne, Snow Barlow, said the paper showed humans were taking up too much of an important natural resource.

"Here we are, just one species on the earth, and we're grabbing a quarter of the renewable resources … we're probably being a bit greedy."

Let's look at this from a rational standpoint. Humans make up about 1,000,000,000 metric tons of biomass, give or take a little. As a species, our population pales in numbers compared to say ants or beetles, but in terms of biomass, we're right up there. We probably out-mass elephants and rhrinos and bears, etc, combined. 25% of the resources doesn't seem so great considering that we can't eat the 75% of other things like trees and grass and shrubs.

Would it be churlish to suggest that anyone who admits to having a given name like "Snow" should be ignored as a matter of general principle?

And Barlow? A distant relative of Mad Maude, perhaps .....
