  • Why caring for our oceans is so important S25 Ep36

    This week, listen in to Jill Grant exploring the importance of our oceans and chatting about some great organisations that are working to protect this amazing global resource and habitat.

    Oceans cover 70% of the Earth’s surface and they provide a vital regulator of global climate and weather through their currents that transfer heat from the Equator to the Poles and dictate rainfall and wind systems with vital impacts on food production, water supplies and habitation. They also directly supply food, fibres, recreation, transport and medicines, all of which bring societal benefits.
    Coastal wetlands cover less than 1% of the earth’s surface yet they store 50% of seabed carbon – more than 2-4 times that of forests on a per area basis. They can help reduce climate change impacts by storing carbon from the atmosphere in “carbon sinks” This so called “Blue Carbon” is identified as a major contributor to efforts to reduce overall emissions and subsequent increases in global temperatures – the impacts of which are becoming more intense and more frequent.
    If Australia is to meet its recently promised targets of a 62-70 percent reduction below 2005 levels within the next 10 years then action must be accelerated and well placed. It seems that ocean conservation, litter reduction and water quality improvements are just some of the specific efforts to increase carbon storage potential on our extensive coastline.

  • Celebrating Nagambie’s Grey Box Grassy woodlands…under a shadow S25 Ep33

    Nagambie locals and Goulburn Broken Catchment Management Authority are celebrating 30 years of revegetation work with local native grey box trees grassy woodlands (trees and understory) on Friday. Classified as an endangered environmental community in 2010, Grey Box and derived Grassy Woodlands are iconic. This is our vegetation backyard in the Goulburn Valley. They have enjoyed 30 years of ecological restoration, and deserve some celebration.

    Celebrate! Friday Sept 12th, Somewhere Café on the Nagambie Lake, 9.30 to 12.
    But here’s the catch. At the same time, the Elloura Estate in Nagambie, on Vickers Road and reaching North to the lake edge, are again wanting to remove a healthy stand of aged mature Grey Box trees. The irony is breathtaking. Ellouramarkets itself as an exceptional masterplanned community…offering stunning water or park views. It takes so long to grow a stand of Grey Box trees and associated grassy woodlands(and a park view), but a housing estate wants to bulldoze a healthy cluster of this woodland. …Trees that are a focus for the estate (in a creative mindset) and offer shelter in hot weather and a changing climate. Exceptional planning?
    The 51 trees campaign saved these trees less than a decade ago, and now they return to the firing line.
    Donna Winter-Irving is an active Nagambie resident and neighbour to the development. Donna joins EarthChat to chat about the forthcoming Grey Box and Grassy Woodland event, and share her concerns about the threatened healthy cluster of mature Grey Box trees on the Elloura Estate.

  • Dr Karl gets excited about our ability to address climate change S25 Ep32

    Renewable Avenel Energy is hosting a half day expo on 22/8 “Take the heat out of climate change with home-based solutions & renewable energy“. The informative and entertaining Dr Karl Kruszelnicki headlines an impressive line-up of guest speakers.

    This Tuesday, Dr Karl joins EarthChat. Peter Lockyer captured Dr Karl in a recorded interview during the week, and this will be shared with John Hyland and Jim Billings from Renewable Avenel Energy  in the EarthChat studio. Dr Karl is all positive energy: a long-time advocate of recognising the science behind climate change, and making changes to a low carbon economy sooner. “We have the technology, we just need the political will” to get to net zero by 2050. Insurance companies recognise a climate change urgency, but waivering leadership is letting many of us down.
    The Home Energy Expo has many features of interest to all- trade displays, service providers, government agencies and the veritable sausage sizzle.  John and Jim will explain all. More details about the expo are here.

  • BEST OF EC: Making the fashion industry more sustainable S26 Ep29

    (Originally broadcast on 12 August, 2025)

    The fashion industry has been revealed as a major source of waste especially those fabrics which contain a high proportion of synthetic and plastic compounds which take a very long time to degrade and leave a toxic legacy, often far from where they are manufactured or purchased.
    So called “Fast Fashion” is placing a huge burden on waste streams and the natural environment and while consumer behaviour needs significant education and changes there are excellent collaborations happening between designers and scientists to minimise impacts at all stages of the fashion life cycle.
    We have two guests on EarthChat for this topic. Firstly, Dr Christopher Hurren, Associate Professor in Fibre Science and Technology and a lead researcher with the Institute for Frontier Materials both based at Deakin University. He specialises in the development of new fabrics and the repurposing and recycling of textiles from a wide range of sources to conserve resources at both manufacture and end of life.
    Our second guest is Peter Allen, Executive Officer from the Refuture Foundation and partner with SRU Consulting.  Peter is an expert in reducing waste across a range of consumer products and packaging. His work with State governments and private industry has given him an excellent understanding of consumption, use, disposal and recycling patterns. Peter is going to discuss his recent travels to Ghana, Dubai and Copenhagen and the innovations he observed there.
    Listen in and learn about the true cost of our obsession with "fashion" and what can be done to reverse the tide.

  • Tracks and Trails in Mitchell Shire S25 Ep30

    This week, we discuss the proposal to develop tracks and trails throughout Mitchell Shire. We chat about the possibilities of developing links  within the shire and also with neighbouring shires. We will look at the health benefits of walking and cycling in the environment. We will also examine the need to protect our natural treasures.

    The planned growth in the population in the Shire means that we need to plan for our future now. Estates being developed now should include provision for safe walking and cycling to schools and public transport as well  as local health and shopping access.
    Special guests Pauline Duff and Tim Budge from the Mitchell Alliance for Tracks and Trails (MATT) join Marie Gerrard on EarthChat as they discuss a dream to make the most of our rural environment in a sustainable way.

  • Straw bale houses in Australia and India S25 Ep29

    Ravish Sran commissioned Peter Lockyer to build a straw bale house in his family village in Punjab, from 2016 to practical completion in 2020. Ravish was impressed with straw bale houses in Victoria, and together with his mother liked one in Nagambie. “This house in India can demonstrate energy efficient housing”.  Passive solar design, rainwater harvesting and in-ground brick tanks, straw bale walls of rice straw, saved from being burnt as “rubbish”. And rooftop solar. Completed, it does attract interest. But does it change housing design?

    What is the interest, and are there Government incentives to build energy efficient houses in India? Is this just the province of the wealthy? Ravish Sran joins Peter Lockyer on EarthChat and they discuss THAT house, and opportunities and barriers to smarter house design and construction.
    Want an idea of what it looks like in practice? Here is fun video about the house.

  • NAIDOC 2025, the Next Generation: Strength, Vision and Legacy S25 Ep26

    NAIDOC Week this year marks a powerful milestone: 50 years of honouring and elevating Indigenous voices, culture, and resilience. The 2025 theme, "The Next Generation: Strength, Vision & Legacy," celebrates not only the achievements of the past but a future, empowered by the strength of young Indigenous leaders, the vision of communities, and the legacy of ancestors. The NAIDOC journey began as a movement for recognition and rights, sparked by Indigenous communities who saw a future built on justice and equality. Over the decades, it has grown into a powerful national celebration, a testament to the endurance of Aboriginal and Torres Strait Islander peoples.

    As we all commemorate this 50-year legacy, Tim and Jill chat to Darrell Lego, a member of the local organising committee for NAIDOC week in Seymour and Mitchell Shire. Darrell will talk about the great events planned for the local area in the week, including the annual celebration on Wednesday 9th July.
    Darrell will also gives us some background on himself as a Gunditjmara man, some background of NAIDOC and some more information about the great activities planned for the celebration on 9th July.
    Music this week is from Youngblud and also Rhyan Clapham (aka Dobby) - a drummer and rapper of indigenous and Filipino heritage who uses his music to express his thoughts on environmental issues like how the Murray-Darling River system has been over irrigated with subsequent fish losses etc. Through his songs he seeks to connect with people and call for action. He also collaborates with the Busking for Change initiative run by musician Josh Pike where funds generated from the sale of the music are used to support the Indigenous Literacy Foundation. His latest project is called "Country Tells Us When". We played the song "I Can't Breathe"
