@Ruth_Mottram casting as intrinsic flaws of individuals what are more properly attributed to properties and failures of socioeconomic systems will not help solve our sustainability problems.
People on their own are mostly simple and make tangible choices: pick the polluted megacity over the desolate countryside, a warm home over a cold one, convenience over hassle. Risks must be *very* visible to trigger response.
Its actually good news. Systems can change easier than "deep flaws".
