Why would an ordinary scientist blog about billionaires? I claim relevance because I reckon that the world would be a lot better off if we valued careful investments of society’s hard-won wealth on behalf of all citizens and life on this planet more that feathering the nests of a tiny fraction of humanity who use their extreme wealth to pursue their own agendas.
There are so many chemical elements that are critical for life on earth - but mankind is paying such little attention to them - seemingly just one at a time. And we can’t even solve the problems surrounding the cycling of just one of them - carbon!
If only we were all educated about the vital importance and wonder of key elements, we could solve the globe’s problems so much more quickly.
Here, we see the media presenting some in-depth understanding about two of the most important elements - nitrogen and phosphorus - but with too much focus on the elements of fear and danger!
A few reflections on why I had to quit Twitter - to protest against this valuable informal ‘town square’ being used by its new rich owner to further his own interests. I look forward to the evolution of a new world ‘town square’ which excludes anonymous participants and where, by design, vested interests are minimised.
“The future is in our hands” … “it is our urgent task today … to repurpose (the march of the megamachine) … so it may serve the needs of all life on Earth …” What an inspiring talk by Professor Roberto Trotta - his final lecture at Gresham College in the UK - which spans from the largest dimensions to the smallest lifeforms on our “pale blue dot” spinning through the universe!
My concerns about Marshall’s well-delivered ‘sales pitch’ include trust in science, obstacles to collaboration, the importance of job security and the need for our national research agency to be free from commercial conflicts of interest.
Having created such a valuable national resource 96 years ago, surely it is time that our nation recognises that CSIRO’s strategic research for industry and the public good is of vital ongoing importance to the nation and should be funded accordingly.
What I might have written to myself 50 years ago about my future career in agricultural science.
It is not a question of tilting at windmills! If the blades of a wind turbine absorb some of the wind’s energy, allowing us humans to warm our spa baths, won’t that wind now contain less energy?
Sadly, in Australia, our governments listen to the latest Pied Pipers instead of seeking out objective facts from its agricultural and land management science agencies. Thank you to Geoff Thompson and Background Briefing for their podcast “Boom time in carbon farming country”!
If you are interested in food and how it might be produced more sustainably, you might like to read what this ordinary scientist has written …
Why is it that most humans take their food for granted?
Throughout history, societies have behaved as if our food supply will last forever - until it doesn’t!
I argue here that it is perilous for us to have a ‘Magic Puddin’ view of food - and of the agriculture, farming and our precious soils which produce it.
Grazing management means that the farmer chooses how much and the quality of the diet a grazing animal is offered as they are moved from paddock to paddock over time.
If it is done well - taking into account issues of the climate, grazing animal, pasture, soil and profitability - it can result in good animal and pasture outcomes.
However - if it is done poorly - such as when systems are not flexible, it can reduce the animal’s choice of diet which can have a flow-on effect of lower animal production.
Unfortunately, there are no simple recipes for success that are widely applicable.
Doesn’t everyone want to stop global heating? Perhaps not!
Here I suggest that there is an ‘elephant in the climate’ that no-one discusses: those many people who live at high latitudes, largely in the wealthy, influential global north, who experience really cold winters and who are welcoming a degree or two of global heating.
How can we overcome this obstacle to developing a global consensus? One that accepts that messing with the Earth’s thermostat is a really scary thing to do!
