‘Jacuzzi vents’ model CO2 future

Sunday, February 19th, 2012

“A UK scientist studying volcanic vents in the ocean says they hold a grave warning for future marine ecosystems.

These vents have naturally acidified waters that hint at how our seas might change if atmospheric carbon dioxide levels continue to rise.

They are conditions that would make it harder for corals and similar organisms to make the hard parts in their bodies.

Dr Jason Hall-Spencer’s work suggests our oceans could lose perhaps 30% of their biodiversity this century.

The Plymouth University researcher has been presenting his latest findings to a major conference in Vancouver, Canada.

“I am investigating underwater volcanoes where carbon dioxide bubbles up like a Jacuzzi, acidifying large areas of the seabed, and we can see at these vents which types of organisms are able to thrive and which ones..”

Acid oceans turn ‘Finding Nemo’ fish deaf

Monday, June 20th, 2011

“Clownfish, the spectacular tropical species featured in the movie Finding Nemo, appear to lose their hearing in water slightly more acidic than normal.

At levels of acidity that may be common by the end of the century, the fish did not respond to the sounds of predators.

The oceans are becoming more acidic because they absorb much of the CO2 that humanity puts into the atmosphere.”

Stop polluting Belize’s tropical rivers and stop the smokescreen, Probe International tells Fortis Inc.

Wednesday, October 7th, 2009

“International aid and trade watchdog, Probe International, is asking Stanley Marshall, President and CEO of the Newfoundland-based power company Fortis Inc., to start accounting to the people of Belize and its shareholders about contamination of the Macal and Belize Rivers in Belize by the company’s Chalillo dam.

Aerial photographs released in early August show that the dam is discharging sediment-laced water and contaminating the downstream river with turbidity levels hundreds, if not thousands, of times higher than the standards set by the World Health Organization and the U.S. Environmental Protection Agency. The contamination has now reached the Caribbean Sea.

Turbidity contaminants are especially worrying, says Patricia Adams, the author of the letter and Executive Director of Probe International, because (more…)

Cruise Ships Produce 168,000 Gallons of Sewage Daily

Thursday, July 2nd, 2009

“Pollution from cruise ships is a growing problem, according to environmental group Oceana. They produce a large amount of pollution every day from sewage, garbage and solid waste, toxic chemicals and oily bilge water.

According to Oceana, the average cruise ship produces the following pollution daily:

  • 25,000 gallons of sewage from toilets
  • 143,000 gallons of sewage from sinks, galleys and showers
  • Seven tons of garbage and solid waste
  • 15 gallons of toxic chemicals
  • 7,000 gallons of oily bilge water

Several cruise lines have been making efforts to clean up their acts, reports Seattle International Travel Examiner. The newspaper cites several examples — including Princess Cruises, Holland America, Carnival, Royal Caribbean, Celebrity and Norwegian Cruise Line — where cruise lines have implemented environmental measures.

As examples, both Princess Cruises and Holland America have ships that plug into onshore hydroelectric power while in port, which reduces the air pollution produced by idling ships. Holland America has also installed a special seawater-scrubbing emissions system to reduce air pollution, and uses a hybrid power system in its newer ships.

Smaller cruise lines, such as Lindblad Expeditions and Adventure Smith Explorations, have also implemented environmental measures, which include offsetting their carbon footprint, purchasing seafood from sustainable sources, and adopting new sustainable technologies, according to the Seattle International Travel Examiner.

But not all cruise lines are in agreement.”
