« La production effrénée de plastiques engendre une pollution aux impacts croissants, qui entraînera des coûts considérables à mesure que les crises qu’elle suscite se multiplieront. En ce qui concerne la crise climatique, l’industrie plastique est responsable de 5,3 % des émissions mondiales de gaz à effet de serre (chiffres de 2019). Si rien ne change, ces émissions pourraient doubler, voire tripler d’ici 2050. »

Added complexity allows an economy to grow, even as resource limits are reached. But at some point, the complexity itself becomes a problem.
2023
A major reason for the growth in the use of renewable energy is the fact that if a person looks at them narrowly enough--such as by using a model--wind and solar look to be useful. They don't burn fossil fuels, so it appears that they might be helpful to the environment. Energy modeling misses important points. I believe that profitability signals are much more important.
Many people believe that wind, solar and electric vehicles are solutions to our energy problems. In this post I talk about the important role complexity plays. Growing complexity uses energy in hidden ways. The result tends to be more energy use, rather than less, as complex solutions such as wind turbines, solar panels and electric vehicles are added. Many measures of energy desirability give unreasonably favorable ratings to wind and solar and electric vehicles. The problem is that dual systems are needed, driving up energy consumption. Without enough energy, economies tend to collapse. This is a form of simplification.
