Degrowth Economics

Degrowth economics is the most politically explosive proposal on this list, deliberately shrinking rich-nation economies to stay within planetary boundaries. It challenges the growth-centric logic that underpins #9 Lab-Grown Meat, which aims to decouple consumption from emissions. A 2020 study in *Nature Climate Change* found that degrowth scenarios can reduce CO2 by 40% by 2030 while improving well-being indicators, using a carbon budget of 2.3 tonnes per capita annually. However, the approach remains politically toxic: only 7% of global voters support mandatory economic contraction, and no major democracy has adopted it. Proponents argue that without addressing overconsumption, efficiency gains like renewable energy or lab-grown meat will be overwhelmed by rebound effects. Critics counter that degrowth risks collapsing social safety nets, raising inequality by 15% in modeled transitions. This trade-off—drastic ecological security against democratic consent—keeps degrowth as a radical yet essential debate, outperforming any voluntary lifestyle fix in academic credibility but failing against market-based solutions in real-world traction.
