Help Protect Australias Coral Sea

The Coral Sea is a tropical marine jewel which lies east of the Great Barrier Reef Marine Park. It’s one of the last places on Earth where large marine animals can still be found in great numbers. It’s one of the last remaining places on Earth where populations of large ocean fish – sharks, tuna and billfish – have not been drastically reduced. With 90% of large ocean fish gone from the world’s oceans over the last 50 years due to overfishing, this makes the Coral Sea worth protecting. The Coral Sea has spectacular coral reefs, remote islands, towering underwater mountains and deep-sea canyons. Its abundant wildlife includes whales, dolphins, sea turtles, sharks and rays; seabirds; large ocean fish such as tuna, marlin, barracuda and swordfish and a diverse range of corals and reef fish.

We need to act now before it is to late. These beautiful natural santuraries are under threat and we cannot let them be destroyed!

Cruise ships and large commercial ships will be banned from dumping any kind of sewage along California’s coast

Cruise ships and large commercial ships will be banned from dumping any kind of sewage — even highly filtered wastewater — along California’s coast out to three miles from shore, under new rules from the Obama administration.

The rules, which are scheduled to be announced Wednesday at a news conference in San Francisco, give California among the strictest laws in the nation limiting pollution from large ships.

“This is going to cover the entire California coastline,” said state Sen. Joe Simitian, D-Palo Alto. “Oceangoing vessels should not consider our coastline a place for dumping sewage.”

In 2005, Simitian wrote a bill that Gov. Arnold Schwarzenegger signed banning sewage discharges in state waters from cruise ships and commercial ships larger than 300 gross tons.

That bill — the first of its kind in the nation — made it illegal for such ships to discharge oily bilge water, “gray water” from sinks and showers and other hazardous waste. But a key provision that also banned sewage releases could not legally take effect until the U.S. Environmental Protection Agency gave permission under the federal Clean Water Act.

Although California asked the EPA for permission in 2006, the Bush administration did not act on the request.

Officials at EPA regional headquarters in San Francisco declined to comment Monday, saying they would wait until the formal announcement later this week.

But people familiar with the new rule said it will add legal clarity to the state law, so that if a ship did discharge sewage close to shore, its owner could not claim it was immune from penalties because the EPA had yet to act.

“This is a giant step in the protection of our coastal waters,” said Teri Shore, program director at Turtle Island Restoration Network in San Francisco.

Industry officials said they already are complying with the state law.

“EPA has discussed it in general with us, and we said that if it follows the provisions in the Simitian statutes I don’t think it should be a problem for us,” said John Berge, vice president of the Pacific Merchant Shipping Association in San Francisco.

The association opposed Simitian’s bill but withdrew opposition when a provision was inserted allowing older ships without the capacity to hold treated sewage to discharge it in state waters.

Cruise lines said they also are following the state law.

“We don’t discharge anything within California’s three-mile limit,” said Karen Candy, a spokeswoman for Princess Cruise Lines.

Environmentalists said the clarity from EPA is important, however.

“The cruise lines have pretty much said all along they won’t dump in state waters, but there’s no enforcement,” Shore said. “It’s all voluntary. This gives it the force of law.”

With fears of international travel high after the Sept. 11, 2001 terrorist attacks, cruise ship visits to U.S. ports — particularly California stops such as Monterey, San Francisco and San Diego — grew steadily. By 2006, there were 81 cruise ship visits to San Francisco Bay, carrying 223,000 passengers.

Although the struggling economy has reduced that trend somewhat — to 62 visits and 179,000 passengers last year — the level remains more than double the pre-Sept. 11 numbers.

“Cruise ships have 3,000 or 4,000 people on them. They are little cities,” said Arthur Feinstein, vice chairman of the San Francisco Bay chapter of the Sierra Club. “You can imagine the amount of sewage they put in the water. And they are only getting bigger. So I think this makes a huge difference.”

In 2003, the city of Monterey banned all Crystal Cruise ships after the Crystal Harmony dumped 36,000 gallons of gray water and sewage in Monterey Bay. Simitian said that was the impetus behind his bill.

“I remember picking up the paper and thinking, ‘you gotta be kidding me,’ ” he said. “Their answer was ‘we didn’t break any rules.’ I remember thinking, if this isn’t against the law it ought to be.”

Mekong River Dolphins Almost Extinct

Heavy pollution in the Mekong river has pushed freshwater dolphins in Cambodia and Laos to the brink of extinction, the

World Wide Fund For Nature (WWF) has said. Reported by the BBC, WWF said that only 64 to 76 dolphins remain in the

Mekong.

High toxic levels of pesticides, mercury and other pollutants have been found in more than 50 calves that have died since

2003. The group said it was investigating how contamination had entered the Mekong, and has called for a cross-border plan to

help the dolphins survive.

Its time to act on ocean acidification or suffer the consequences

A statement signed by 70 of the world’s leading science academies stated “Ocean acidification is expected to cause massive corrosion of our coral reefs and dramatic changes in the makeup of the biodiversity of our oceans and will have significant implications for food production and the livelihoods of millions of people”.

The world’s top scientific academies on Monday called on the UN (which started a 12-day round of negotiations in Bonn under the banner of the UN Framework Convention on Climate Change) to include ‘ocean acidification’, which is a dangerous by-product of carbon pollution in their discussions.

The UNFCCC is tasked with steering 192 parties towards a deal in Copenhagen in December of this year which is aimed at setting down targets for curbing greenhouse-gas emissions by the middle of this century.

Martin Rees, President of the Royal Society said: “Everybody knows that the increasing concentration of carbon dioxide in the atmosphere leads to climate change. But it has another environmental effect, ocean acidification which hasn’t received much political attention. Unless global CO2 emissions can be cut by at least 50% by 2050 and more thereafter, we could confront an underwater catastrophe, with irreversible changes in the makeup of our marine biodiversity. The effects will be seen worldwide, threatening food security, reducing coastal protection and damaging the local economies that may be least able to tolerate it. Copenhagen must address this very real and serious threat.”

Climate change – caused by carbon dioxide and other greenhouse gas emissions

Its frightening to realize that every 4 hours a forest the size of Manhattan is lost to the world.

According to Conservation International and other environmental experts climate change — caused by carbon dioxide and other greenhouse gas emissions — threatens species, biodiversity and life on Earth as we know it. The destruction of tropical forests across the globe contribute as much as 20% of the world’s greenhouse gas emissions ( more than all the world’s cars, trucks, and airplanes combined) and advances climate change. Human activity is the main cause of deforestation, usually tied to economic development, increasing consumption rates – in both developed and developing countries – and extractive industries such as logging. It is important that we consider using alteratives to virgin timber from rainforests and forests. Always look at sourcing reclaimed or recycled timber furniture or timbers that are FSC sourced.

One of the most important things we can do to improve the climate is to work towards conserving forests — the lungs of the Earth. New York Times columnist Tom Friedman in his new book Hot, Flat, and Crowded, explains how protecting forests is among the quickest and most cost effective solutions available to us to assist in the slow down of climate change. It can be put into effect immediately. Unfortunately, every day beautiful pristine jungles (home to wildlife, ecosystems, and over half of all the species on Earth) are burned and cleared for farming and ranching, or for plantations to produce biofuel crops. It has been reported that loggers extract more trees than the forest can reproduce, destroying ecosystems and leaving roads that invite other exploitative forces.

Forests are important ecosystems in the balance of nature, providing a multitude of resources and services essential to all people the relentless and ongoing destruction of habitat and resources not only lead to increases in climate change but also can lead to the displacement of people who depend and live within these beautiful eco systems. Where do people like this go to? Where do they end up? This impact results in poverty and social displacement and in turn instability.

According to the Intergovernmental Panel on Climate Change, halting deforestation and restoring already degraded areas while adopting more forest-friendly agriculture and management practices would prevent the emission of more than 300 billion tons of carbon dioxide over the next 40 years (that is more than total U.S. emissions over that same period, based on current levels).
