FROM THE EDITOR

In any national crisis we inevitably look to political leaders to formulate policies that will at least mitigate and, hopefully, ultimately resolve it. However as the Covid pandemic proves yet again it is primarily ordinary people doing their bit – medical staff, bus drivers, lab technicians, volunteer food deliverers and on – who actually get us through it.

With climate change, pandemic and political unrest it is easy to be overwhelmed by the magnitude of the problems humankind currently faces. But then you find an example of one person who has a simple solution to a big problem. In fact in this instance, several problems in one go. Aluwaine Manyonga, SLL Young Lighter 2020, has devised a solar-powered LED lantern that not only provides a viable alternative to the widespread use of toxic kerosene lamps in Africa, but manages to do it by recycling plastic bottles and electronic waste (Solar recycle, p5). There is also potential for creating employment. As Manyonga says, it could be a game changer.

If ever there was a person who believed you could move mountains if you only put your mind to it, it was Liz Peck. A former SLL secretary and then president, she fitted more passion, energy, service and commitment into too few years than many people who live twice as long. We pay tribute to her in this issue (Light and soul, p11).

As statesman and philosopher Edmund Burke put it, 'Nobody made a greater mistake than he who did nothing because he could do only a little'.
