Most people have heard about how rising CO2 levels are resulting in a changing global climate.
Fewer have heard about the other consequence of rising CO2 levels- when the CO2 is absorbed into the oceans, it disassociates into carbonic acid. This alters the pH of our world's oceans, and it's called "Ocean Acidification
". This changing ocean chemistry has many important and devastating consequences. [more inside]

1/3 of open ocean shark species faces extinction, according to the IUCN.
A recent report by the International Union for the Conservation of Nature's Shark Specialist group shows that nearly 1/3 of open ocean shark species face extinction. These sharks are essential to keeping ocean ecosystems in balance, and we've already seen some of the devastating effects of catastrophically decreased shark populations. Shark advocate Wolfgang Leander offers his thoughts on this crisis, and also provides the full text of an article about this IUCN report.

Imagine nature's most elegant ideas organized by design and engineering function, so you can enter "filter salt from water" and see how mangroves, penguins, and shorebirds desalinate without fossil fuels. That's the idea behind AskNature
, the online inspiration source for the biomimicry
community. The featured pages
are a good starting point. Cross-pollinating biology with design. [more inside]

:"In the spring of 2003 about 8,000 tribal people and low-caste farmers living in the Kuno area of Madhya Pradesh, India, were summarily uprooted from the rich farmlands they had cultivated for generations and moved to 24 villages on scrub land outside the borders of a sanctuary created for a pride of six imported Asiatic lions."[via

, who spent most of her life in Kenya, was a noted naturalist and filmmaker (along with her (former) husband
. She was murdered
by gunmen at point-blank range in January, 2006 in her home on Lake Naivasha
. Lake Naivasha is the only fresh water source in the Great Rift Valley
, and has become increasingly endangered by pollution and overuse for irrigation, and Root spent considerable time fighting to protect it. Today, a Kenyan magistrate acquitted
the four suspects in her murder, calling the testimony of 13 witnesses "defective".

The Save Our Seas Foundation [small Flash]
, a Swiss-based non-profit, joins the growing ranks of a world-wide movement to undo the damage caused by popular reports
and gross misrepresentation by Hollywood
of sharks as human-savoring sea monsters/killing machines. The fact of the matter is that the opposite is true: Current estimates give between 65 million to 165 million sharks being killed worldwide annually via unregulated catch - including 38 million
to 70 million [PDF]
for their fin alone, with untold numbers of butchered and bleeding-to-death sharks being cast back into the oceans to die slow and gruesome deaths. [more inside]

design that saves mucho energy, does not require air conditioning, does not require heating even when outdoors it's 10 below!
Since, for example, more than 30% of energy consumed in the UK is for homes and 82 per cent of that is space and water heating, [Monbiot, "Heat,"chapter 5, "Our Leaky Homes,"] changing our standards of home design is important. Diagram
shows that basic solar design concepts are well understood and technically easy to implement in new construction. [If only my house could be turned 45 degrees!] Possibly through ignorance, and partly through the desire to cut corners instead of doing things right, we do not make these wise concepts a priority. There are lots of cool alternative
building techniques, many of which are traditional and being revived
. This leading design standard saves 90% of energy used in the home
. Here in Canada it's called the net zero energy home.

During the 19th century, thousands of men took to the seas to hunt for whales. The indigenous peoples of the Arctic practiced whaling for several millennia before that. Technological change and changes in mores have reduced the whaling industry to a heavily regulated shadow of what it used to be. But it hasn’t disappeared altogether. Even now, at the dawn of the 21st century, ships prowl the seas in search of a spout or a gigantic fin. A few months ago, Outside magazine published an account of a whale hunt aboard the Norwegian ship Sofie.

is a feritle hybrid of cattle and buffalo (bison bison
). It's story cannot be told without mentioning the irascible "Buffalo" Jones
, the man who helped save the American buffalo and tried to cross-breed cattle and buffalo. He called it cattalo
Later successful hybridizations gave way to the beefalo
. Some cite the near-extinction and later ultimate repopulation of the buffalo to free-market
forces such as the private herds kept by Buffalo Jones for creating sustainable cattalo .

Extinct is forever

Scientists are hard at work reconstructing entire genomes of our common ancestors. The present technology is a far cry from Jurassic Park, but we're getting there.
