The Great Barrier Reef. Beautiful one day, an open sewer the next?

India expects to use coal imported from their Australian mines to power some of their planned 455 coal-fuelled power plants. For this to happen it's expected that The Great Barrier Reef will have even more coal terminals built along its fragile, stressed reef to fill massive tankers which will then be manoeuvred through the treacherous channels between the reefs then around the world.

What could possibly go wrong?

The 350.org India co-ordinator Chaitanya Kumar said "what we now need in India is a dramatic shift in policy that puts sustainable and clean energy access as a priority."

Link here to a petition to share concerns that ...
Indian companies GVK and Adani are proposing a series of mega-mines in Australia’s Galilee Basin to fuel their coal power expansion plans. GVK has just received approval for its controversial “Alpha Coal Project” that includes a massive new coal terminal right in the middle in the Great Barrier Reef World Heritage Area. Adani Group has plans to build what would be, by far, Australia’s biggest coal mine, along with another massive coal export terminal at Abbot Point and nearby Dudgeon Point.
It's not that India is tardy in investing in sustainable alternative energy. In fact they could show countries such as Australia how to use solar panels to prevent evaporation from irrigation channels as can be seen in the photo from Gujurat.

A friend recently said to me, surely the coal industry filters their waste water carefully before releasing it back into the environment, and especially when it's near the Great Barrier Reef?

A recent email from Greenpeace gives the following information that would make my friend's toenails curl in horror (my bold):

"There are 250,000 million litres of polluted water sitting in coal mine pits in the Bowen Basin – that’s the equivalent of 100,000 Olympic swimming pools. Some of this water has been there for two years. Instead of treating the water to remove harmful toxins, the coal industry has spent the last two years lobbying for permission to release their polluted water into Queensland’s waterways.

These waterways feed into the Fitzroy River downstream to graziers, towns, the city of Rockhampton and eventually, the Great Barrier Reef World Heritage Area.

Last week, Premier Campbell Newman told Queensland Parliament “the government will not do anything to in any way degrade the feed water coming down the Fitzroy for their water supply.”

That same day, Deputy Premier Jeff Seeney introduced new legislation that allows that to happen.

The Deputy Premier is proposing to create new provisions within the Environment Protection Act that would enable the coal companies to pollute our waterways.

We need to show the Premier that legislation permitting our environment, including the Great Barrier Reef, to be polluted is not acceptable. Send him this message today urging him to pull the Deputy Premier into line and to defend our drinking water and the Reef from the coal industry. 

This new legislation will give companies the opportunity to ask for permission to release their toxic water into Queensland rivers, beyond the standards and guidelines set for safe drinking water and agriculture at short notice and without public review. 

Please tell Premier Newman we need protection for our waterways and our precious Great Barrier Reef from the coal industry."


Link here to petition to let the Queensland government that allowing rampant pollution along the world Heritage Listed Great Barrier Reef is completely unacceptable.

Given that Australia is considered to be the driest inhabited continent on earth, the interior has one of the lowest rainfalls in the world, and around 3/4 of the land is arid or semi arid, it seems insane (perhaps criminal is a more fitting word) to allow coal mining companies to pollute our fragile and precious waterways.

Pollution in waters outside Gladstone affects fish, the fishing industry, tourism and many locally owned and operated local businesses. Lesions in fish are common, which makes them unsuitable for sale. More information here and here.

This issue affects more than Queensland and their government which seems to be in a state of dribbling, salivating lust about squandering finite fossil fuels to overseas countries. Whether we like it or not, we're all connected. Foolish, shortsighted decisions made in Australia affect people in far off lands, India included. Our governments - all our governments and policy makers - need to have a basic grasp of environmental cause and effect to ensure that our world remains relatively inhabitable.

Politicians, no matter where they are have the ability to push in a direction that ensures shortsighted decisions aren't made. How they choose can have devastating consequences for humankind.

Unfortunately, in Australia the motto often seems to be 
"Dig it, drill it, sell it off and stuff the future" 

Perhaps our politicians need to receive training in "How to say no" to the fossil fuel companies.

Climate Matters. X is for eXtreme Weather

This post is for X in the A-Z BloggingChallenge 2012. Link in the sidebar.


Unseasonal snow, high winds, heavy rains, increased heat, damage to property, increased hospital admissions and deaths. Around the world reports of damage from extreme weather events are heard - "unprecedented", "rainfall deficits", "longest drought",  "crop devastation", "unseasonal weather", "homes without power for days", "highest known temperatures exceeded", "all time high"; this it seems, is the new normal locally and globally. 


In recent human history, extreme weather events have, statistically, been relatively rare. Due to our changing climate, the atmosphere is warmer due to complex inter-relationship of events.  For instance, warm air is able to hold more water whilst being less stable, leading to more volatile weather patterns.

Worldwide, heat waves are longer and hotter, heavy rain and flooding is more frequent. Severe storms are increasing in frequency and severity. As is expected, variation in weather patterns is evident and affected seasonally and by local geography such as rivers, lakes and mountains.

Seafront properties take the brunt of severe winds, rain and storm surges.
Computer modelling showing expected range of naturally occurring temperature variations both with and without human contribution shows that human contribution has increased the likelihood of hotter overall temperatures. (For why scientists talk about probabilities rather than certainties see A Advertising here) Upper atmosphere jet streams, swirling ocean currents, the melting of glaciers and permafrost all play a complex and interlinked part in our global weather systems.

People around the world are experiencing the effects of increasingly severe and more frequent storms. The insurance industry is already factoring extreme weather damage into their premiums; they understand that damage will be significant in years to come and have been proactive in encouraging governments to adapt and prepare. They've also been working with industry to address future needs as a result from climate change and the impacts on property and threat to life from global weather instability whether it be preparing for increased heat waves, snow, wind, cyclones or hurricanes.
Low lying industrial areas are at risk of flooding and damage during severe stormsToxins, oils and other contaminants run into surrounding waterways creating havoc for shipping and poisoning fisheries and marine life to say nothing of loss of work and income by those affected. Cleanups are costly and can take many years leaving affected areas uninhabitable.


The heart break from rebuilding shattered lives is impossible to calculate in financial terms.
Remote areas are affected with roadways being washed away leaving farm properties stranded and creek beds susceptible to increased erosion from vehicle traffic.
Financial aid is finite and decisions need to be made whether to replace infrastructure in remote locations after flood damage.
In the recent past, communities affected by storm damage have relied on governments to assist with rebuilding and other support, but that appears to be less reliable as governments are increasingly stretched financially and decide how to most effectively divvy up their budget.

They may choose not to assist as more and more regions are impacted and infrastructure will be left to local communities to manage as best they can. Food security, transport breakdown, water impurities and general displacement impact on communities worldwide and will continue to do so as we experience this change.

Encouragingly though, communities around the world are planning with hope for the future and coming together to share information, resources and ideas to improve the resilience of their towns and regions. They're working together to create a vision for their new communities based on common goals related to making their communities vibrant places to live post Peak Oil. See also H Health here.

Climate Matters. T is for Trees.

This post is for T in the A-Z Blogging Challenge 2012. Link in the sidebar.

Trees are integral to our life on earth: 
"The tree breathes what we exhale. When the tree exhales, we need what the tree exhales. So we have a common destiny with the tree. We are all from the earth. And when the earth, the water, the atmosphere is corrupted, then it will create its own reaction."
(More complete quote below)

Yet, despite the understanding that we need trees to provide oxygen and clean the air we breathe, deforestation is increasing at an extraordinary rate.  People the world over are concerned at the rate at which the Amazon and other rain-forests are being felled, displacing native peoples and decreasing viable habitat for native animals. We've been warned that not only is this devastating to those peoples and their traditional lands, but that it has negative consequences for the whole planet.

Forests of all types, from the apparently insignificant Mangrove (see M here) to towering Mountain Ash  to the vast tropical areas with their astoundingly rich biodiversity, all play a vital part in removing carbon-dioxide from the air we breathe. As forests worldwide are felled, not only are they unable to continue removing the carbon-dioxide we have emitted into the atmosphere, but they release that which they have been storing, adding to the dangerous levels that so concern the bulk of our Earth's best regarded climate specialists.

When forests are clear felled, it impacts on everything nearby. Fruiting trees, glorious flowering plants, nesting birds, animals and fish are all impacted. Where there was a cacophony of diverse birdsong, hoots, chirrups, coughs and vibrant colour, there is less stable soil, burned acres, muddy runoff, pollution from the burning and increased erosion.

Whilst rain-forests appear rich, the soil itself needs the constant addition of falling leaves and debris to maintain the amazing growth. Mono crops, often palm and corn, are planted in their place and generally need the addition of complex fertilisers and pesticides to be viable. The runoff poisons waterways, impacting peoples and their lands many kilometres downstream. The diverse plant, animal and fish communities are unable to return to what is, in effect, barren land.

Why are we continuing on this path which has been of concern for years? In its simplest term ... money. Palm oil is a remarkable substance. Soaps and shampoos wash extremely well when it's added. It's added to sweets, chocolate, breakfast cereals, margarines, laundry and kitchen detergents and moisturisers and more recently added to some fuels. When you start looking it seems to be everywhere, possibly under a different name, but it's there, and it's cheap to produce and valuable to multinationals.

What can we do? Becoming a savvy consumer can be time consuming and it's frustrating to untangle the web of names that are used for palm oil. One local site I use for information and products is chooktopia here.
Indigenous peoples throughout the world have had an understanding of the principles of sustainability, and have lived sustainable lifestyles, for millennia. Floyd Red Crow Westerman, a Hopi Indian elder described the sustainability relationship as one based on an understanding of spirit and the transience of human lifespans. He describes the problems of sustainability as humanity’s inability to live on earth in a spiritual way. He describes that if humanity is not spiritually connected to the earth and does understand the spiritual reality of how to live on earth, it is likely humanity will not survive. “Everything is spiritual. Everything has a spirit… Water is sacred. The Air is sacred. Our DNA is made of the same DNA as the tree. The tree breathes what we exhale. When the tree exhales, we need what the tree exhales. So we have a common destiny with the tree. We are all from the earth. And when the earth, the water, the atmosphere is corrupted, then it will create its own reaction.” The recognition of spirit and the sacredness of our ecology and interconnectedness with the earth and each other is the first bottom line of a quadruple bottom line principle of sustainability. 
 Quadruple Bottom Line 
 Spirit + Social + Economic + Ecological

Climate Matters. M is for Mangroves

This post is for M in the A-Z Blogging Challenge 2012. Link in the sidebar.


Mangroves are often seen to be an expendable part of the marine environment. They don't have the majesty of towering Mountain Ash or the dramatic bark of Ghost Gums or Snow Gums. Westernport Bay in southern Victoria is home to the southernmost stands of our Earth's mangroves - the area is listed under the International Ramsar Convention for protection of migratory birds.

These mangroves are squat, insignificant, slightly muddy smelling and seem to have small crabs perpetually running around the air roots. If you happen to carelessly step off the nearby packed earth, you'll sink to your knees in none too pleasant mud which is difficult to remove. There is a strange musical sound as air pockets pop in the greyish mud.

So, why bother agitating for them to be saved when developers move in to reclaim land or sea for refineries, housing, harbours or fish farming?

Mangroves are a salt tolerant plant and are concentrated along many coastal areas. They store a huge amount of carbon, up to 4 times more than tropical rain-forests, so when they’re cleared, carbon, which is a green house gas, is released into the atmosphere. Their complex root systems which anchor the plants into the underwater sediment and slow down the incoming tidal waters, allow organic and inorganic materials to settle and decay extremely slowly, making them in effect, a high carbon storage tank.

We need mangroves to store carbon, not to release it. 


Many animals and other creatures are dependant on mangroves to survive and are threatened with extensive clearing. Crabs, birds, insects and fish may be reliant on each other for survival, and many have adapted to the salty environment and inter-tidal changes. Mangroves provide safe breeding grounds for fish and their leaves break down providing nutrients for a variety of other creatures.

Increasingly in Indonesia and Thailand, mangroves are being cleared for aquaculture. Many varieties of imported prawn (shrimp) are farmed in ponds and tanks, which can be fed from already stressed and overfished wild populations. Unfortunately, environmental regulations may not be stringent, so there is the potential for untreated run off and pollution being released into the already degraded local areas.

Rising sea levels, extreme weather events and storm surges impact more dramatically when the mangrove buffer has been cleared, destabilising the sand and mud. Sound planning guidelines need to be implemented to safeguard communities along these important coastlines.

By protecting mangroves, we not only capture carbon, prevent erosion, and safeguard communities, but encourage fish breeding and maintain the habitat of endangered and migratory birds, local reptiles and mammals which are threatened with extinction if the current rate of mangrove loss continues.

Climate Matters. J is for Jellyfish

This if for J in the A-Z Blogging Challenge 2012. Link in the sidebar.

Jellyfish don’t strike me as being the most appetising creature in the sea. In fact, I think they look decidely unpallatable. But I’ve been told that with overfishing and the changing pH levels in our oceans that they will become more abundant and we might need to start finding some tasty recipes as fish stocks plummet and species become extinct.

One indication that ocean pH levels are changing and becoming unbalanced is when Jelly fish “blooms” occur. Pollution and overfishing affect jellyfish – they adapt quickly to take advantage of the changes and breed very quickly creating a bloom or infestation.

Overfishing in oceans worldwide has resulted in less predators. Because there’s less competition for food, jellyfish thrive and can reach plague proportions. The overfished species struggle to recover as the jellyfish feed on fish eggs and small fish.

As the temperature rises, as is happening with climate change, the ocean chemistry changes. What happens with warming waters and the dilution from arctic and antarctic ice, is a bit similar to when you put cold milk in a cup of coffee, creating currents within and between the different temperature liquids. They mix at different rates. When you add winds, heated land, ocean currents, storms and tides, it enables warm water jellyfish to migrate along with the warming waters and reach new environments. 

At times jellyfish which have adapted and survived in plague proportions become a pest to shipping when they clog ship filters. Beachside holiday locations become undesirable and local economies suffer.
Man-o-war
Algal blooms occur when algae die in vast quantities, stripping oxygen from the water. Jellyfish can survive in these low oxygen dead zones which can also be created by urban pollution and agricultural run-off. The rising levels of carbondioxide in the oceans affects the brains and central nervous systems of fish which increasingly interferes with their ability to survive and evade predators but which doesn't affect jellyfish.

Urban runoff occurs when we put fertilisers and pesticides onto crops, and in our gardens. When it rains, the residues run into waterways, rivers, lakes and eventually into the oceans as a polluted soup - along with garbage, cigarette butts, and litter, affecting the breeding cycles, breeding ability and health of whole fish populations.

Heavy metals get into the oceans, from smog which is absorbed by the water, and from other sources of pollution (think oil spills, run off from mines etc.) This is absorbed by little fish, which is then eaten by bigger fish, which is then eaten by bigger fish again which are then eaten by us. These bigger fish are the Tuna, Salmon, Flake etc. of the oceans. This is a form of bioaccumulation where we essentially eat the fish with the highest density of heavy metals.

The Australian Marine Conservation Foundation has noted that overfishing and destructive fishing practises have led to “An incredible 80% of the world’s fish stocks are now over-exploited or fished right up to their limit. Once considered inexhaustible, our oceans are now in a state of global crisis, and they need our help.”

The Australian Marine Conservation Society has prepared this excellent guide for the many Australians who love seafood but also love their oceans. "it’s not enough to simply buy what is fresh. If we want to keep eating fish we’ll have to learn to buy what is sustainable.” Tim Winton, Australian Author, AMCS Patron.
