This meeting focussed on discussing what we mean by sustainability. Members of BRIDGE CLUB brought objects and materials that all have some element of sustainability, whether they are locally produced, recyclable, or durable. Dr Joan Farrer challenged the group to consider : How sustainable is it? Is it really possible to be sustainable? Is a classic designer shirt worth hundreds of pounds more sustainable than high street fashion because it will be kept forever and handed down to future generations? She referred to original theorists including James Lovelock, who proposed the Gaia hypothesis in the 1970s, a revolutionary theory that the Earth is a self-regulating super-organism.
