With 2024 being the hottest year on record to date, researchers across the globe are addressing the temperature rise by rethinking our food systems and encouraging the switch to a plant-based diet.

Their Study Solving Climate Change Requires Changing our Food Systems

I know this article is probably not surprising many people, but theres a few interesting parts, like,

The study explains how our growing demand for meat and animal products is unsustainable, with the United Nations Food and Agriculture Organisation (FAO) estimating that demand for meat will double by 2050.

“This demand will require approximately 80 percent of existing forests and shrubland to be converted into land devoted to raising animals. Such a trajectory would have devastating consequences for us and the planet,” Professor Knight said

And,

The study presented strategies to re-think current food systems, including the removal of government subsidies and higher taxation of animal products to account for externalised costs of animal agriculture.

    Corporations are not people. They have no diet but greed. Stop blaming the consumer, asshats.

      You might need to eat food, but you don’t need to eat meat.

      In any case, it’s not one versus the other, it’s all of the above.

      For international travel, there’s just never going to be a better option than flying. Ships are far, far too slow. And suggesting that people not be allowed to go on holiday and experience other parts of the world would be the most out-of-touch unrealistic claim someone could make.

      For domestic travel, we absolutely should have high speed rail, starting with Brisbane to Melbourne, and ideally extending up to Cairns and across to Perth eventually. But unfortunately we don’t have that right now, and it’s unreasonable to ask people to drive or do intercity trips on the insanely expensive yet excruciatingly slow intercity trains we have today.

      But, especially since the amount of carbon emitted by Taylor Swift alone absolutely dwarfs the transport-related-pollution caused by over a thousand average folk (never mind adding in all the other billionaires and celebrities), asking individual people to sacrifice their quality of life for this just isn’t going to, pardon the pun, fly.

      In the short-to-medium term, the vast majority of domestic business travel could probably just be done via Teams or Zoom. And longer term, most domestic travel should be HSR. But that still leaves quite a lot of flying. And there are other places where we can have a bigger impact.

        Without any bias whatsoever, i think the first Aussie fast trains should be on the West Coast. Probably just a shortish line from Augusta to Geraldton. ;)

          You joke, but that “shortish line” would actually be considerably longer than the current actual planned first stage, being Newcastle to Sydney.

      Totally agree, people, especially Australians, need to change our attitudes to our current flight systems, be it the high emissions technology, or an overall reduction in flight hours per person.

      Years ago i listened to a course on energy. I might have to look up the details, but he said the absolute worst common use vehicle for emissions is jet ski’s. I think he meant in regards weight to fuel expenditure ratio.

        Jet skis feel like a vehicle that would be ripe for electrification. The extra torque or whatever that helps them accelerate so fast in cars would surely be an advantage for the type of fun jet ski users like to have. And they’re not usually going to be used for hundreds of kilometres that would benefit from the greater energy density that fossil fuels have anyway.

        But I dunno, maybe I’m missing something.

          You got me interested. Had a read of a random article on them, here you hit the nail on the head with the idea about torque.

          Seems the expense, charging time, and distance travelled on one charge combine to hold them back.

            Yeah looks like range might be worse than I was expecting. I thought you’d be able to get 3–6 hours or so, which would be sufficient for an afternoon of fun. But the first one on that page only gets 1 hour at 60 km/h. That’s definitely a real limitation. Much more real than the limitations on EV cars are today.

            While reading your comment I immediately thought of this company that’s using hydrofoils to overcome the energy requirements in their watercraft: https://candela.com/p-12-shuttle/ Also, recent video here of a trial usage of it: https://www.youtube.com/watch?v=5fqnbskTAjI Very cool.

            I see that that article does actually mention hydrofoils (and seems to link to a video with one), but the specific product they mention is the Sea-Doo Rise which is a board, not a ‘scooter’ style vehicle (video here: https://www.youtube.com/watch?v=GthLd2i01uk). That one seems to be a dead product, though.

            I did find some hydrofoiling electric jet skis, though:

              That hydrofoil ferry looks impressive. Kinda hope they go for something like this for the Perth ferry terminal expsnsion, but i don’t even know if they’re planning on buying new ferries.

              I’ve never been jet skiing, so i don’t know how people get theirvfun out of it. I’d imagine some of the fun is derived from the tight cornering and ocean spray which a hydrofoil jetski would reduce significantly.
