Like many of us who are mindful of our plastic consumption, Beth Gardiner would take her own bags to the supermarket and be annoyed whenever she forgot to do so. Out without her refillable bottle, she would avoid buying bottled water. “Here I am, in my own little life, worrying about that and trying to use less plastic,” she says. Then she read an article in this newspaper, just over eight years ago, and discovered that fossil fuel companies had ploughed more than $180bn (£130bn) into plastic plants in the US since 2010. “It was a kick in the teeth,” says Gardiner. “You’re telling me that while I am beating myself up because I forgot to bring my water bottle, all these huge oil companies are pouring billions …” She looks appalled. “It was just such a shock.”
