To address the relationship between the crises of capitalist growth and democratic politics, this paper discusses the notions of degrowth and conviviality. Both concepts are often interpreted as making similar proposals in response to questions of environmental transformation. However, they bear on different strands of critique. While degrowth criticizes the momentum of capitalist accumulation, conviviality originates in the search for alternatives to the instrumental use of technologies in industrial societies. Although these two rationalities predominantly go hand in hand in the development of modern societies, they are sometimes in conflict and different strategies are required to deal with their consequences. Therefore, the differences between degrowth and conviviality should not be obscured. Instead of using the concepts in an ethical or moral fashion as normative claims directed at some diffuse agency of states, companies and the people, the paper argues for a thorough examination of issues and propositions to overcome the environmental crisis from the perspective of materialist science and technology studies. Since one key factor here is the level of global production and consumption of meat, this paper turns toward a controversial attempt to break new ground in meat production: the vision of artificially producing meat in the laboratory. Lab-grown, cultured meat provides a powerful case study for exploring political and democratic challenges of post-growth societies, all the more so as questions of animal welfare and interspecies conviviality are addressed as well. By taking a closer look at the role of animals in proposed solutions for degrowth and conviviality in meat production and consumption, the complementarity of such claims can be questioned, and a light can be shed on the inherent political implications of such technological innovations.

为了解决资本主义增长危机与民主政治之间的关系，本文讨论了“消长”和“欢乐”的概念。经常将这两个概念解释为针对环境转变问题提出类似的建议。但是，它们承担着不同的批评。消极增长批评资本主义积累的势头，而欢乐则源于对工业社会中工具性使用技术的替代寻找。尽管这两个理性在现代社会的发展中主要是并存的，但是它们有时会发生冲突，需要采取不同的策略来应对其后果。因此，不应掩盖除臭和活力之间的差异。本文主张从唯物主义和科学的角度彻底审查问题和主张以克服环境危机，而不是将这些概念以道德或道德的方式用作针对某些国家，公司和人民的分散机构的规范主张。技术研究。由于此处的一个关键因素是肉类的全球生产和消费水平，因此本文转向有争议的尝试，以突破肉类生产的新领域：在实验室中人工生产肉类的愿景。实验室种植的养殖肉类为探索后增长社会的政治和民主挑战提供了有力的案例研究，此外，还解决了动物福利和种间友好性问题。
