Are younger people, defined by age, or younger generations, defined by cohort-level measures, more concerned about declines in environmental health when compared to their older counterparts within the United States? Related, are these same people more willing to support policy actions aimed at preventing future losses when compared to older adults? In spite of reporting by the U.S. popular press about the heightened environmental consciousness of Millennials, prior research offers conflicting answers. Scholarship focusing on age effects suggests that the answer to both questions is yes due to the dampening of environmental concern and action in older adults. More recent applied research on climate related risks and risk management options, by contrast, suggest that the answer to both questions is no, and that there is no difference in climate concern and risk mitigation between younger and older adults. In an attempt to disentangle these contradictory viewpoints, we undertook a study in which respondents in the United States characterized by age and generational cohort were presented with small and large hypothetical losses due to climate change. These same participants were then asked to indicate their support for future policy actions aimed at stemming these environmental losses. Overall, our data does not indicate that younger generations experience potential losses as more acute than older generations; neither age nor generational cohort correlated with the perceived severity of environmental losses nor support for future actions to prevent them. More robust predictors of both dependent variables were environmental value orientations (biospherism) and self-reported political orientation.
与美国的老年人相比,年轻人(按年龄定义)或更年轻的一代(按队列水平定义)是否更关注环境健康的下降?相关的是,与老年人相比,这些人是否更愿意支持旨在防止未来损失的政策行动?尽管美国大众媒体报道了千禧一代对环境问题的认识有所提高,但之前的研究给出了相互矛盾的答案。关注年龄效应的学术研究表明,由于老年人对环境问题的关注和行动减少,这两个问题的答案都是肯定的。相比之下,最近关于气候相关风险和风险管理选择的应用研究表明,这两个问题的答案是否定的,并且年轻人和老年人在气候问题上的关注和风险缓解没有区别。为了理清这些相互矛盾的观点,我们进行了一项研究,在美国,按年龄和代际队列划分的受访者被要求描述由于气候变化而导致的小损失和大损失。然后,这些参与者被要求表示他们对未来旨在遏制这些环境损失的政策行动的支持。总的来说,我们的数据并没有表明年轻一代比老一代更能感受到潜在的损失;年龄和代际队列都与环境损失的感知严重程度或对未来预防行动的支持无关。对两个因变量都更具预测性的是环境价值取向(生态主义)和自我报告的政治取向。
