Study Identifies 15 Top Threats to Biodiversity

"Widespread development of nuclear power and seabed-located oil drilling are among the top 15 threats to biodiversity in 2013, according to a new study published this month in the journalTrends in Ecology & Evolution."

~ Beth Brogan, staff writer

Biofuels seemed to "promise to be a green alternative to fossil fuels, but no-one anticipated that pristine rainforest would be cleared for them."

~ Professor Bill Sutherland, University of Cambridge, United Kingdom.

fossil fuel independence, energy independence. Separate these two issues. Oil is in well defined decline since 2000. Ladder for growth ...?

What Climate Change Just Might Ruin

Thanks to Ruth Anthony-Gardner

"According to a 2011 U.S. Interior Department report, "annual flows in three prominent river basins - the Colorado, Rio Grande and San Joaquin - could decline by as much [as] 8 percent to 14 percent over the next four decades," reported the Associated Press. Expected changes in temperature and precipitation are likely to alter river flows 'with increased flooding possible in the winter due to early snowmelt and water shortages in the summer due to reductions in spring and summer runoffs.' 

"Mike Connor, commissioner of the U.S. Bureau of Reclamation, said, "Impacts to water are on the leading edge of global climate change." 

"Earlier this year, the Bureau of Reclamationasked the public to suggest ideas for meeting future water demand around the Colorado River basin."

As our technology increases, so goes our "carrying capacity", which is why the word sustainable is no longer useful... carrying capacity is entirely dependent on economics and technology. It's why so many people are going vegetarian... the argument being... we'll need to feed more people so we need to become vegetarian! (along with a few other arguments of course). Spaniards are building vertical gardens, also increasing the Iberian peninsula's "carrying capacity". It is a value which is impossible to pinpoint. I come back to the number of humans must be in proportion to the numbers of large animals... any other standard is movable, flexible, cheatable.

TNT666, when I use the word "sustainable" I mean human beings living within the carrying capacity of our planet. No particular economic theory implied.
I do agree with your sentiment that thinking breeding is a "right" is as ridiculous as the "right" to own slaves".
