Graph showing the mass fraction of initial mass (y axis) over time (x axis). The mass fraction is either in particulate classes (microplastics), dissolved, or CO2 (mineralised). The mass fraction starts as entirely in particulate classes, before rapidly transferring to dissolved and then quick onwards to CO2. After 100 days, approx 25% of the mass is mineralised, and by 400 days, the particle and dissolved fractions cannot be seen on the graph and CO2 makes up >99% of the mass.

Three graphs showing the mass-based release of secondary microplastics, secondary nanoplastics and dissolved organic carbon (DOC) from the five polymers for three different aging protocols. PA-6 shows highest release of DOC and no significant particulate release. HIPS and LDPE show high microplastic releases and lower DOC and nanoplastic releases.

Graph showing a species sensitivity distribution for immidacloprid in water. On the x axis is the no observed effect concentration (ranging from 1e-3 to 1e4), and on the y axis is the proportion of species affected. Markers shows individual data points for different species, and a line shows the modelled probabilistic species sensitivity distribution.

We should condemn the targeting of all civilian life, no matter who does it. That this is apparently controversial is testament to the depravity of a media and political class that shuts down, distorts and denounces calls for peace. The heinous attacks on civilians in Israel by Hamas were utterly deplorable. This cannot justify the indiscriminate killing of Palestinians, who are paying a price for a crime they did not commit. All human life is equal. Why is it so difficult for our politicians to be consistent in this basic moral principle? This is the question that many people in this country are asking when they express solidarity with the Palestinian people. They are not expressing support for Hamas. To deliberately conflate the two is a disgusting, cynical and chilling attempt to further erode our democratic rights, and wilfully ignores a very basic demand: to stop the killing of innocent people.
