Reduce the following paragraph by about 20%, retaining the formal style, and without losing semantic meaning: "In the 2020s renewed interest in monetary diversification has re-invigorated the pursuit of frameworks for anchoring money supply and worth to primary commodities. Earth Reserve Assurance (ERA) framework resolves distortions and complications which are inherent in the diverse earlier proposals that would relate money to one or many physical primary commodities, by shifting the reserve concept back one stage in the value chain, so that the Earth itself is the ‘warehouse’. The natural productive capacity of Earth's functional ecosystems consists of factors such as the quantity and quality of topsoil, fresh water, deposits of metal, minerals and energy, species populations, diversity and integrity, local, regional and global land and water habitats, biogeochemical cycles, and other types of infrastructural capacity underlying the ability to obtain primary commodities. The ERA framework offers an incremental path to sound money, to be deployed through existing currencies, and builds on the complementary strengths of physical and electronic modes, while holding to all four of NAME_1' ideal functions of money: “medium of exchange”, “means of payment”, “unit of account” and “standard for deferred payment”, this design is well suited to the current global shift towards diversification of both payments and reserves.
