Sharp drop of consumption
Living like monks won’t work, because a drop of consumption would slow down the economy, destroy jobs, and increase inequality, especially with the younger generation, unable to get an entry job to learn basic skills.
Instead, we have to consume green electricity, recycling services, batteries, even a lot of them to create a demand by corporations, to create jobs, and perhaps to diminish inequalities.
Economic growth (of the GDP) must not be capped. GDP growth is not just about producing dirty objects. It includes also services such as healthcare or recycling. Finally, economic growth is about job creation.
