According to the New Economics Foundation, "[t]he world moved into 'ecological overdraft' on Saturday, the point at which human consumption exceeds the ability of the earth to sustain it in any year and goes into the red". While it is not definite that this is the case, the article "World moves into the ecological red" includes some very scary and eye-opening facts. This one struck me as particularly poignant:
"If everyone in the world had the same consumption rates as in the United States it would take 5.3 planet earths to support them, NEF said, noting that the figure was 3.1 for France and Britain, 3.0 for Spain, 2.5 for Germany and 2.4 for Japan."
Thank you to Graham, who wrote in to alert us of an article entitled "Is light pollution killing out birds?" which states:
"Recent research has shown a reduction in the populations of moths, spiders, sparrows and amphibians, supporting the case for light pollution being considered a threat to the environment as well as to astronomers - who find the glare interfering with their observations - and householders - who complain of the visual intrusion caused by security lights and insensitive street lighting."

Just some more food for thought.
