If you're at a university that's still using X, could you ask them to follow suit?
You can point out how embarrassing it would be to be the last university left at the Nazi Bar and Non-consensual Nudity Emporium! 😬

If the Government's top priority is productivity, slashing the CSIRO budget does not make sense
Research and development is one of the major drivers of productivity and the CSIRO has a long track record of making productivity enhancing breakthroughs.

Now, instead of imagining the plastic floating out in the ocean for hundreds of years, making a mess and endangering marine life (yuck), imagine more and more CO2 pollution floating up in the atmosphere for hundreds of years, making a mess and endangering all forms of life (super yuck)
It's astounding how much CO₂ we put into the atmosphere each year by burning fossil fuels.
For comparison, we all agree that plastic pollution is bad, but the mass of ALL THE PLASTIC humanity has ever produced is only 25% of the CO₂ we emitted into the atmosphere in 2025.

1) Fossil fuel
Still no peak. Emissions are projected to increase by 1.1% in 2025, reaching 38.1 GtCO2. An all time high.
