- "Why Access to Morphine is a Human Right", 4 May 2018: "That millions of sick people throughout low- and middle-income countries suffer horrendous pain because they cannot access the morphine they need is a tragedy — the result of unwarranted fears and a failure of governments to care for those most in need."
- "Thriving in the Age of Factory Farming", 14 September 2017: a reflection on the paradox of wanting to derive pleasure from existence while there is massive, legally sanctioned torture of sentient beings taking place within our societies, and on the need for balance in our own lives so that we can be more effective as activists.
- "#MeToo? Reflections on abuse, power, gender and species", 18 October 2017: "Most of us are or have been, to some degree, both victims and perpetrators of abuse of power, sexual or not, conditioned by our society in our beliefs about what is appropriate, about what is normal, about what is “right” and “wrong”."
- "The Ethics of Impact", 17 March 2015: a piece I wrote for the Huffington Post's Pioneers for Change blog on a few key principles for ethical action.
