We took to the streets in Sydney this past weekend, along with hundreds of thousands of other concerned people all over the world, to call for evidence-based policy decisions in the best interest of humanity and the planet. Worryingly, as we all know, science and even basic truthfulness is currently under heavy attack in US politics. We nearly didn’t make it out the door to get to the march in time, thanks to a series of pretty standard parenting mishaps…but we persisted nonetheless, both for the sake of making out voice heard and teaching our children to do the same. Hopefully, in the coming years, the pendulum will swing back towards fact- and evidence-based decision making. But if not, at least we’ve primed our personal next generation to get out there and keep on shouting until it does.
