EDITORIAL

The coronavirus pandemic has seen the inevitable cases of human greed, selfishness, stupidity and exploitation. But outweighing them has been the human impulse to reach out and help, to respond with humour, compassion and creativity, and to shine a light in the darkness. We may be physically distanced but we are finding different ways of coming together.

A modest initiative quickly came from the SLL, the ILP, the IALD and Zumtobel Group UK who have united to create the Light Minded Movement, an Instagram project allowing the lighting community to communicate through images (see p4). There will be many more such endeavours, simple, spontaneous and positive.

What we can only hope is that we learn a lesson from this, though history is not encouraging. As writer and environmentalist George Monbiot put it in The Guardian, 'We have been living in a bubble... of false comfort and denial. Now the membrane has ruptured, and we find ourselves naked and outraged, as the biology we appeared to have banished storms through our lives.'

FROM THE EDITOR

Our cavalier disregard for our planet and its ecosystem is all part of the same syndrome. As John Bullock points out in his examination of the circular economy (see p5), the lighting industry has to look to its own backyard in this respect. 'The temptation, when this pandemic has passed, will be to find another bubble,' continues Monbiot. 'We cannot afford to succumb to it. From now on, we should expose our minds to the painful realities we have denied for too long.'
