Last night, one of the last images I saw before I went to bed was of a terrified Chinese toddler being held at knifepoint in the street by her father. The horror of that situation was not distilled by the frozen photo, the detached computer screen, or the fact I could flick away when I chose. Horrendous fear and suffering were transmitted in an instant.

I hadn’t searched this out. I wasn’t planning to read the news at that point. But it broke its boundaries and affected me. As did the Four Corners story this week, which I found out about thanks to twitter. I’m grateful I didn’t have to watch that footage, because I know it would still be haunting me. The photographs I did see were enough.

No one has taught me how to deal with these moments. I have had to teach myself, because, quite frankly, they have brought me to my knees at times. And the way I have come to terms with this is by becoming a more conscious guardian of my emotions, knowing when I can take action and when there is nothing I can do. From what I could gather (the article wasn’t clear), the little Chinese girl was rescued. Twelve hours later, the news has moved on, and I can’t even find it on the same site. I’m pretty sure I won’t ever know what happened to them.

However, with the push to ban live exports, there were at least petitions to sign. Where once upon a time I would have felt this was a fairly unremarkable gesture, I don’t any more, because of the emergence of a few amazing, energetic sites that have recorded some brilliant, measurable breakthroughs as a result of people power. Sites like Avaaz.org and getup.org.au (who ran a live exports petition), and organisations like the Wilderness Society (who send you the results of their actions) are doing a great job of bringing some critical issues to our attention. And despite the desperate, depressing news they bring to my door, they make me feel that there is something small but very important that I can do. They wouldn’t exist unless we were all choosing to add our names to causes we believe in. This weekend my family will be going to climate change rally in Perth on Sunday (there are also rallies in Melbourne, Hobart, Brisbane, Adelaide and Sydney), thanks to the information and reminders from GetUp. Our voices might be small, but they all count, and I’m buoyed by the words of anthropologist Margaret Mead: Never doubt that a small group of committed people can change the world. Indeed, it is the only thing that ever has.col-md-2
