One possible earlier process that could have led to the change advertised on the poster is the implementation of new environmental policies or regulations. If the poster is promoting a cleaner and greener environment, it is likely that there were changes in legislation or public awareness campaigns that were implemented prior to the progress being displayed.

From the poster, we can infer that there was a shift towards more sustainable practices, such as recycling or reducing carbon emissions. This could have been prompted by growing concerns about climate change, pollution, or resource depletion. The poster may be a result of ongoing efforts to address these environmental issues and promote a more eco-friendly lifestyle.
