The One Planet Development (OPD) approach means people can (locally) produce a percentage of their own "wealth" (resources) sustainably. https://qoto.org/@Empiricism_Reloaded/110511036586999020
To be clear, the OPD approach means people will own their own land and home (e.g., self-ownership or cooperatives). Therefore, the OPD approach is more about self-sustainability and less reliance on a Global economy. For example, if your generating your own electricity & a percentage of your own food without using fuels, Russia or Saudi Arabia can't blackmail your country (or vice versa. We could all do with less unethical geopolitics)
As things stand (business as usual), what do you think would happen if other countries stopped supplying the USA with oil? Americans crying at the gas pumps 😭 would not be the worst of it.
Do you know that the current dominant USA (& Europe, etc) food system can't function without fossil fuels? (e.g., fertilizers, insecticides, machinery, transport).
The OPD integrates with the local ecology to grow food sustainably using virtually no fuels. It's all about reducing resource and power demands (AKA efficiency) and focusing our attention on what really matters (healthy food, healthy culture, personal autonomy, etc)
