It sounds like you're starting to tell a story about how Newtown has changed over time. Here's a possible continuation:

"Many years ago, Newtown was quite different. The streets were often littered with trash, and the air quality was poor due to industrial pollution. However, after a community-led cleanup initiative began in 2005, things started to improve dramatically. Local businesses got involved, residents formed recycling programs, and strict regulations were put in place to control emissions. Now, it's hard to imagine that Newtown ever looked any other way. Parks were created from former industrial sites, and green spaces now dot the landscape. Newtown has truly become a model of urban renewal and environmental stewardship."

This continuation provides context for the change and paints a picture of the town's transformation. If you'd like to explore a different angle or have specific details you want included, please let me know!
