My prediction -—
The ‘harvesting’ of methane at new facilities will be a failure, exposing fraudulent promises of money generated for poverty relief/drug eradication.
The ‘recycling’ of polluted water generated will prove to be a pathogen vector for disease and swiftly abandoned. Once the world-attentive games are over, landfills will quietly go back into use and trash-pickers back into business.
