Ecologist: The issue is cooperation

The Sustainable Hour no. 418 | Podcast notes

Guest in The Sustainable Hour on 29 June 2022 is ecologist and scientist Harald Ehmann, while Heidi Fog delivers her sixth episode of ‘The Sustainable Endpoint’ series – this time she explailns about what her family does to cut emissions at home.

Harold Ehmann is a long time ally to First Nations Australians. Harold tells us about his current studies in Northern Flinders Rangers in South Australia, an area he keeps returning to as he studies the yellow-footed rock wallaby. We learn about the changes he has seen in both the flora and fauna in that particular area, and that he doesn’t see climate change as being the main cause of the degradation he has observed. We also learn about low cost methods they have implemented to help restore numbers of his beloved yellowfooted rock wallabies.

Harold has been very much influenced by his observations of and experience of working beside First Nations people as they manage the land they nurture – a much different approach to industrial farming practices which have destroyed so much of the land.

“Waging kindness, care and compassion for Peace, Harmony, Equality, Simplicity and Sustainability on and beyond Kaurna Country” is Harold’s sign-off for emails he sends out. As we speak to him it becomes obvious just how accurate this self-assessment is.

Harold leaves us with two videos of a study area of the yellow-footed rock wallaby – and the changing vegetation in the Northern Flinders Ranges.

. . .

We have been running a series of Heidi Fog‘s “The Sustainable Endpoint” with tips for reducing carbon emissions. Today she gives us invaluable information on how we can reduce the amount of resources (the word “waste” isn’t in her vocabulary) that we throw out. She emphasises that if we make wise choices around what we buy, it saves both money and the material we throw out each week. These wise choices save on packaging, save money and make for a more healthy lifestyle.

. . .

The songs we play are Midnight Oil‘s “To The Ends Of Our World” – and “Every Day Is Earth Day” by Paul Izak, Sam Ites and Maadking.

Colin Mockett‘s Global Outlook starts with a new report that shows that the global generation of electricity by offshore wind projects has almost doubled over the past twelve months, from 429 gigawatts of capacity a year ago to 846 gigawatts today. Colin goes on to give the figures and the leading countries going down this essential energy pathway.

Then to the United Kingdom, where three Cambridge engineers have filed a patent for their invention of the world’s first emissions-free way to create and recycle cement. The trio have landed a grant of £1.7 million to allow them to collaborate with Warwick University and Imperial College London to reveal the underlying science behind the process. Professor Allwood said: “If Cambridge Electric Cement lives up to the promise it has shown in early lab trials, it could be a turning point in the journey to a safe future climate.

Colin proceeds to describe the process. It is reckoned that this system could secure the supply of the basic materials of construction for a zero emissions world and enable sustainable economic development where it is needed most.

Further to this, a complimentary report from the United Kingdom has found that renewable energy creates three times as many jobs per million pounds invested compared to fossil fuels. And for energy efficiency measures, this rises to a fivefold increase. The report called for a new UK-wide nationwide programme of energy efficiency and heat decarbonisation retrofitting in UK buildings that would stimulate ongoing low-carbon jobs for the coming decades.

Finally, we zoom to the the world renowned Glasonbury Festival where last weekend 100,000 people flocked to the Somerset venue where the headlines showed the festival’s oldest artist – Paul McCartney who played a set with guest Bruce Springsteen, but the surprise attendee was Greta Thunberg, who appeared on the main Pyramid stage and in her blunt style criticised world leaders for creating loopholes that enabled companies and nations to avoid their climate responsibilities. She said the Glastonbury crowd could make a difference and urged them to take a stand. She got the crowd chanting ‘Climate Justice and left the stage to applause as warm as any other artist including McCartney and Springsteen. And that upbeat note ends Colin’s worldwide roundup for the week.

“If humans go extinct it will be because they don’t cooperate.”

“We are approaching the precipice and I would strongly suggest that all of those who have not yet been greenwashed out of our senses to stand our ground. Do you not let them drag us another inch closer to the edge. Right now is where we stand our ground.”
~ Greta Thunberg – on Twitter

We at The Sustainable Hour would like to pay our respect to the traditional custodians of the land on which we
are broadcasting, the Wathaurong People, and pay our respect to their elders, past, present and future.

The traditional owners lived in harmony with the land. They nurtured it and thrived in often harsh conditions for millenia before they were invaded. Their land was then stolen from them – it wasn’t ceeded. It is becoming more and more obvious that, if we are to survive the climate emergency we are facing, we have much to learn from their land management practices.

Our battle for climate justice won’t be won until our First Nations brothers and sisters have their true justice. When we talk about the future, it means extending our respect to those children not yet born, the generations of the future – remembering the old saying that, “We do not inherit the Earth from our ancestors. We borrow it from our children.”
The decisions currently being made around Australia to ignore the climate emergency are being made by those who won’t be around by the time the worst effects hit home. How disrespectful and unfair is that?
Harald Ehmann

Indigenous worldview can preserve our existence

This powerful brief video made by Wahinkpe Topa (Four Arrows) for UNESCO clearly explains some key differences between the Indigenous worldview and that of our dominant culture—and shows why it’s so critical for people to understand this and support our Indigenous brothers and sisters in their struggles as Earth protectors.

“We’re facing the gravest crisis in the 200,000 year history of our species. We’re looking at imminent societal collapse, the death of billions, possible extinction. Yet our plastic consumerist lives mean most people don’t really see this as something to get worked up about.”

The poles are melting

Especially the northernmost Greenlandic glaciers are now melting at record speed. 

This is the conclusion of a study led by DTU Space and published in the scientific journal Geophysical Research Letters.

Melting has increased in North Greenland: Currently 55 percent more ice melts per year compared with 10 years ago

The ice in Greenland is melting due to global warming, which is hitting harder there than in other regions of the world, states senior researcher and co-author of the new study William Colgan from the National Geological Survey of Denmark and Greenland (GEUS).
