What have you done today to lower your impact?

We are washing away the foundations of our existence on every front. It is high time we move from crashing about on the planet like a bull in china shop and find a way to go forward with intent. We must find systems of living based on sustainability. The systems and tools exist, it is up to each of us to adopt them.

Finally, Some Good News About Our Oceans

After the flurry of depressing posts about the oceans yesterday, here are some reasons to be hopeful.

Check out this post by Julie M. over on Celsias;

Finally, Some Good News About Our Oceans

Posted using ShareThis

Here's an excerpt directly pertaining to one of my posts yesterday.

"In another positive move for our oceans, in response to a petition and threatened litigation by the Center for Biodiversity , the U.S. Environmental Protection Agency (EPA) in February agreed to review how ocean acidification should be addressed under the federal Clean Water Act.

Ocean acidification results from the ocean's absorption of excess CO2 in the atmosphere, resulting in increased acidity and changes in the seawater chemistry which in turn can hinder the ability of marine animals to build and maintain their protective shells and skeletons. The Center has asked the EPA to impose stricter pH standards for ocean water quality as well as publish guidelines to help states protect U.S. waters.

The EPA's formal response to the petition sets out a public process to evaluate ocean acidification's impact on water quality, as well as determining whether the current water quality criterion for pH should be modified to address these new concerns. The EPA also agreed to develop biological assessment tools and other technical guidance with regard to evaluating the health of coral reefs that are specifically threatened by ocean acidification."

Acidic Seas threaten mass extinctions

As reported on the BBC, our oceans are now more acidic than anytime in the last 500,000 years, 30% more acidic than at the start of the industrial revolution. This is a direct consequence of increasing carbon dioxide levels in the atmosphere due to human burning of fossil fuels.

Are we so greedy for convenience and comfort that we are willing to sacrifice our oceans!?

While I'm ranting I'd like to point out that the BBC still has a science and environment reporting division, this news is featured on the radio, television, and internet. Please let me know if you see anything on this story on mainstream US media.

Read more at BBC News. Here's an excerpt,

" 'I am very worried for ocean ecosystems which are currently productive and diverse,' Carol Turely told BBC News. I believe we may be heading for a mass extinction, as the rate of change in the oceans hasn't been seen since the dinosaurs. It may have a major impact on food security. It really is imperative that we cut emissions of CO2.' Dr Turley is chairing a session on ocean acidification at the Copenhagen Climate Change Congress." - Roger Harrabin
