Low Levels of Air Pollution Dangerous For Your Heart

This is the first study to assess the effect of real-world air pollution according to environmentalresearchweb:

“Air pollution is bad for your heart – particularly if you are elderly.”

This new animal study provides biological evidence of the well-known finding that air pollution increases cardiovascular disease and mortality.

Turns out that even relatively low levels of pollution — particulates from the burning of fossil fuels or wood — is “reducing the blood’s ability to carry oxygen and perhaps altering neural reflexes too. Meanwhile, the gaseous pollutants might be causing tissue inflammation, leading to less efficient uptake of oxygen through the lungs”.

The affects were worse with age. “It would seem prudent to work towards reducing exposure to these pollutants…”

Yet another compelling reason to end the addiction to fossil fuel use and to also help bring cleaner-burning stoves to the people who need them for cooking. Stephen

Earth Day Wish – The 3 Rules

Take time to be outside today.

Think about everything that nature provides – air, water, plants and animals that sustain us. Such gifts should not be taken lightly for they can vanish or be degraded. With our numbers and powerful technologies we are ‘the bull in nature’s china shop’.

We need to take great care and practice Climate-safe Living.

3 Rules to dial down the temperature on our global greenhouse:

1. Reduce.

Reduce fossil fuel consumption everywhere.

2. Eliminate.

Eliminate all non-essential activities and products that involve burning fossil fuel.

3. Demand.

Demand that business and government provide transport, activities and products that use minimize fossil fuel use.

Reduce. Eliminate. Demand. R.E.D.

May you always cherish this Earth and share in her joys.

Canada’s “Mordor” Ensures Climate Treaty Failure in Copenhagen

[Hello from snowy and cold Copenhagen. Tensions have ramped up as political leaders arrived but are mainly meeting in secret.

Ashamed to say Canada is a widely acknowledged as a public embarrassment here. And called a climate criminal by some. Several protests like the one I covered below and a smaller one earlier have focused on the Athabasca Tar Sands perhaps the world’s biggest source of carbon emissions.

Outside the artificial reality of the Bella Center ordinary people get it. Here is good video summary of what happened on Wed as civil society were gradually banned from the conference. It accords with my son’s version who was in the middle of all this as an observer. — Steve]


By Stephen Leahy

COPENHAGEN (IPS/TerraViva) Dec 14 2009

Climate activists jammed a small square near the police-barricaded Canadian Embassy here Monday for the second day of protests over the country’s tar sands development.

Simultaneous protests were held at the Canadian Embassy in London because British oil companies and financial institutions are deeply invested in the Canadian mega-project.

“As indigenous people, we are here at the international climate negotiations to speak about threats to our cultural survival and the direct life-threatening impacts of climate change in our communities,” said Clayton Thomas Muller, tar sands campaigner for the Indigenous Environmental Network.

“Canada has been blocking the climate negotiations and hasn’t kept Kyoto commitments…because of the tar sands,” he told a crowd of 75 to 100 people surrounded by four squads of riot police.

Boreal forests and wetlands the size of Greece are been destroyed in northern Alberta in an industrial project that turns millions of tonnes of sand and earth into oil, mainly for the U.S. market he said.

“All the efforts by Canadians to reduce their carbon emissions are undone by the tar sands,” said Canadian writer and activist Naomi Klein.

The tar sands are Canada’s largest single source of carbon dioxide (CO2) emissions and the major reason why Canada has refused to live up to its commitments to reduce emissions and is blocking negotiations, Klein told protesters.

“Canada is making a mockery of international law and of developing countries’ need for urgent emission reductions in rich countries,” she said.

Canadian Prime Minister Stephen Harper is here at the Dec. 7-18 U.N.-sponsored climate summit under false pretences, Klein charged.

Harper does not have the Canadian people’s permission to promote the tar sands or to favour Canadian interests over those of the planet,” she said.

The tar sands are “Canada’s Mordor”, said Maude Barlow, head of the Council of Canadians, the largest citizens’ group in Canada. She was referring to the devastated land of rock and fire in the “Lord of the Rings” trilogy.

“What else can you call a project that leaks 11 million litres of toxic waste a day into rivers and groundwater?” Barlow said in this very un-Mordor upscale shopping district of downtown Copenhagen.

The tar sands project has the largest toxic waste containment ponds on the planet – easily visible from space. Last week, a report revealed the extent of the leaks to be an estimated 11 million litres a day.

Shockingly, this is based on the oil companies’ own self-reported data, says Environmental Defence, the Canadian advocacy, research and education group that compiled the report.

It calculated that four billion litres of leakage a year will grow to 25 billion in a decade based on current growth of the tar sands and aging of the enormous dams that hold back the waste.

“There is no question Harper will stand up for  the oil sector [in the climate talks here],” Barlow said.

Their [oil industry] footprints are all over this negotiation and that is why it will fail.”

Global Day of Action Against Monsanto

maize - mexicoCanadians are calling and writing the Minister of Health to ask that she immediately halt the introduction of Monsanto’s new eight-trait GM (genetically modified) corn called “SmartStax” because it was not assessed for safety by Health Canada.

“SmartStax” corn was authorized this summer by the Canadian Food Inspection Agency for planting next year but was not examined by Health Canada for human health safety.

This is part of a global action opposing Monsanto’s genetically modified (GM) crops under the first “International Day of Action Against Multinational Corporations” initiated by the global farmers’ movement called La Via Campesina.

“Its extremely significant that La Via Campesina is focusing their World Food Day action on Monsanto and GM crops. It shows us that farmers around the world see GM crops as a major threat to their survival,” said Devlin Kuyek, a Montreal-based researcher for the international group GRAIN.

Ozone Hole 2009 – Bigger than North America – 24 million sq km

Picture 7

I’m not doing a full article on this year’s Antarctic ozone hole but you should know that the maximum size appears to have peaked at 24 million sq km, less than the 2006 record year 27 million sq km. Although some media reported this as a downward trend, it is too soon to say because ozone depletion is a complicated process and affected by local weather conditions.

Chilean Children Warned to Stay Indoors

The hole moves and shifts overhead like a unseen gigantic amoeba and on Oct 9 officials in southern Chile warned residents that the hole had extended itself over Punta Arenas and warned children to stay indoors and avoid exposure to the very hi-level UV rays.

Children hiding indoors during the day at the southern tip of Chile could have been the fate for much of the planet without the Montreal Protocol treaty 21 years ago to eliminate some of the ozone destroying chemicals used in deodorants and refrigerants.

This ought to be crucial cautionary tale for climate change.

Alien Species Cause Extinctions, Increase Poverty, Erode Ecosystems

Saltcedar, an invasive exotic weed, crowds out native vegetation along the Gila River in Arizona.

By Stephen Leahy

UXBRIDGE, Canada, May 21 (IPS) – Continent-hopping alien species are worsening poverty and threaten the agriculture, forestry, fisheries and natural systems that underpin millions of livelihoods in developing countries, warn biodiversity experts.

“The livelihoods for 90 percent of people in Africa directly rely on natural resources such as marine coastal biodiversity,” said Ahmed Djoghlaf, executive secretary of the Convention on Biological Diversity (CBD).

“Around the world more than 1.6 billion people depend directly on forests for their survival,” he told IPS from Montreal.

Biodiversity is not just fuzzy animals and pretty birds. It is the diversity of life on Earth that comprises ecosystems which in turn provide vital ecosystem services including food, fibre, clean water and air.

“Biodiversity is poor countries’ most precious asset,” Djoghlaf stressed. Continue reading

Bring Back Glass – Ban BPA (bisphenol A) Plastic Containers Now

(This is an important subject but I don’t have time to write a full article  on this so here’s my quick take on two new studies — Steve)

carbon neutral pub77 lucky Harvard student volunteers experienced a nearly 70 percent increase in urinary levels of bisphenol A (BPA), a plastics component and synthetic estrogen linked to cancer, after drinking cold beverages from baby bottles for ONE WEEK.  — Research by Harvard University and the U.S. Centers for Disease Control and Prevention (CDC) published May 13.

The bottles were made of made of polycarbonate, a common hard plastic often used to make reusable bottles/containers among other things. BPA is used to make most polycarbonate and evidently leaches into the water or whatever is in the container.

Another study published May 12 shows that very small amounts of BPA affects the growth of tadpoles: “Bisphenol A stifles thyroid hormone and slows frog development” — this is an easy to read summary from Environmental Health News.

Bottom Line : “The study confirms past research showing BPA interferes with thyroid hormone (Goto et al. 2006, Iwamuro et al. 2006). It is also consistent with studies that show BPA slows and alters development.”

What you can do:

1. Use Glass or Steel Containers – all liquids taste much better in these

2. Insist that plastic containers for water-pop-soda are banned in your workplace, community, district.

3. Lobby for bottle return deposit systems — These are still in place in much of the world and they work fine.

Plastic Bottles Leach Estrogen – ‘Healthy’ Mineral Water Contaminated by Plastic

churning-ocean-sml1An analysis of commercially available mineral waters in Germany reveals estrogenic compounds leaching out of the plastic packaging into the water. What’s worse these chemicals are potent and affected the development of  invertebrate embryos. Estrogen contamination was found in  78% of waters in plastic bottles and waters bottled in composite packaging.

“We must have identified just the tip of the iceberg in that plastic packaging may be a major source of xenohormone* contamination of many other edibles. Our findings provide an insight into the potential exposure to endocrine-disrupting chemicals due to unexpected sources of contamination.” — write the study authors in the journal of Environmental Science and Pollution Research.
