Without the services provided by nature, humanity could not exist so why do we keep destroying nature? Financial institutions have cold feet about investing in Albertas oil sands and the Premier directs a blow torch at their bellies. A follow up to last months Siemens story and hints for environmentally sustainable alcohol intake. Finally, a reminder that the Great Barrier Reef is still in danger.

A report presented to the World Economic Forum in Davos has highlighted the high dependence of the global economy on services provided by nature more than half of global GDP is moderately or highly dependent on such services. This is particularly true in fast-developing countries such as Brazil, India and Indonesia. Agricultural, construction, pharmaceutical and food and drink industries are highly exposed because of their reliance on resources extracted from forests and oceans or on natures ability to provide healthy soils, clean water, pollination and a stable climate. The report also identifies the contradictions in trade agreements between developed and developing countries. For instance, some European countries reject products from countries with big environmental footprints and criticise their use of pesticides while continuing to import their beef and soy and export to them chemicals banned in their own country. While it is appropriate to be critical of the ongoing destruction of nature in developing countries in South America, Africa and Asia, the causes of the destruction extend well beyond each countrys boundaries.

The production of petroleum from Albertas oil sands is very good for Albertas economy (at present) but not so good for the environment, not only because the final burning of the petroleum produces carbon dioxide but also because the process of extracting the petroleum from oil sands produces a lot of greenhouse gases. As elsewhere, financial institutions are beginning to get cold feet about global warming and several have decided to stop investing in Albertas oil sands and/or their pipelines. Moodys has even downgraded Albertas creditworthiness because of its dependence on oil sands. This has prompted a pugilistic response by the Albertan government. It has established a war room to attack anyone criticising the industry, has indicated that it will stop doing business with the deserters, and has criticised the teaching of climate science to school children. The government has also pointed out the hypocrisy of institutions pulling out of Alberta but continuing to support oil production in Iran and Saudi Arabia that have the added complication of terrible human rights records. Defending his provinces actions, Albertas Premier reckons that Its about responding to an existential threat to Albertas and Canadas economy and to the livelihoods of hundreds of thousands of Canadians. Looks to me like climate change is prompting some of the worlds capitalists to squabble over the generation and distribution of the systems surplus value.

Siemens stake in Adani coal mine not even economically sensible is the headline of an opinion piece in one of my go-to sources of information, the blog of the Institute of Energy Economics and Financial Analysis (IEEFA). The text under the header is noteworthy not so much for what it says (climate change is a disaster already; we dont need more coal; global demand for coal is plummeting; the mine will become a stranded asset; financial institutions and contractors are running from Adani because of the financial and reputational risks) as for the credentials of the author, Rob Anderson. I have not previously encountered Mr Anderson but I note that his brief bio describes him as former chief economist at the National Australia Bank and Dresdner Bank, [and] a senior policy advisor to the Australian Treasury and Department of Prime Minister and the Cabinet. Mr Anderson seem to be a bit out of step with the people he advises. (For those in holiday mode in January, Siemenss decision to provide the signalling on the new rail line needed to take the coal away from Adanis proposed Galilee Basin mine was met with a storm of criticism which itself prompted a bellicose response from now ex-Minister Canavan.)

OK, so you like a drink but are worried about the carbon footprint. What can you do?

• Drink less. Maximum of ten drinks per week for women and men is the recommendation of the National Health and Medical Research Council and would be good for the environment too.
• Drink spirits, they generally have a lower environmental footprint because the volume and weight packed and transported is lower.
• Drink local products fewer grog miles. If imported, favour those that have come all the way by sea.
• Drink cask wine. A third of a bottle of wines emissions are in the bottle itself, and of course glass is also heavy to transport. Perhaps time to give Chateau Cardboard another go.
• Drink warm beer well, what would you expect a Pom to say? The largest part of beers emissions is associated with refrigeration. But also remember that cans are better than bottles: lighter and more likely to be recycled.
• Walk or cycle to the bottle shop or pub (youll probably buy less if you have to carry it, no greenhouse gases or air pollution from the car, and good for your health).

Who knew that those little stickers on the fruit you buy can increase climate change?? The stickers are made of plastic and are not biodegradable. This can result in composting facilities rejecting loads of rotting fruit which then goes to landfill instead, decomposes without oxygen and produces methane. Non-plastic alternatives are available.

With the focus, understandably, on the bush fires, the fate of the Great Barrier Reef has been pushed into the background this summer. However, warm seas have started to cause some coral bleaching. The photograph below, showing several bleached corals, was taken by Lyle Vail off Lizard Island on 21 February. The Great Barrier Reef Marine Park Authority is putting out excellent weekly updates on conditions on the Reef. I thoroughly recommend the 3-5 minute video updates for February 20th and 27th by Dr David Wachenfeld, GBRMPAs Chief Scientist.
