The shadow treasury minister Clive Lewis, in a newspaper interview, has said MPs must show leadership, and persuade consumers to make dramatic lifestyle changes, if devastating climate change and mass extinctions are to be averted. Cutting back on red meat and taking fewer flights are two of the ‘real, stark choices’ needed in the years ahead. Lewis said, ‘If you want your children and grandchildren to avoid food shortages, to avoid power shortages, to avoid biological degradation, biodiversity loss - if you actually want a planet that’s habitable - then we need to make some choices together, now, and some of them are about quite dramatic changes to how we live.’
