Well this is very exciting!

Why the WHO has recommended switching to a healthier salt alternative It’s a positive step, but there will be a few challenges to realising the full benefits to public health.

Most of us eat too much salt that's hidden in processed foods. If food manufacturers switched to potassium salt we could all better protect our health & manufacturers still protect their profit margins with potassium-salty foods instead #Salt #SciComm #WHO #Health #processedFood #food #potassium

You don’t have to be a net zero hero – how focus on personal climate action can distract from systemic problems Shifting the blame for the climate crisis onto individuals hides the larger issue. True progress demands systemic accountability from governments and corporations.

Tired of being asked to be a 'Net Zero Hero'? 🦸‍♂️

My new @uk.theconversation.com article explains why focusing on individual action can distract from other climate solutions. 🌎

It's time for systemic change! ➡️

Need a simple way to destress? Stop and notice nature, experts say | CBC Radio On those dreary winter days, it's easy to feel low, but experts recommend a simple way to boost your mood: take notice of nature. Doing so can spark moments of joy called "glimmers."

Research by Holli-Anne Passmore, an associate professor of psychology at Concordia University of Edmonton, indicates that simply noticing nature, even briefly, significantly enhances positive emotions such as joy, connectedness, hope, and gratitude.
