I think that the world is a better place after covid-19 for several reasons. During the Covid-19 pandemic many indoor facilities were temporarily closed, large gatherings were banned, and mask or face coverings were mandatory. There are three reasons how the world can be a better place after Covid-19.
Somebody said I would also put the ending sentence before you tell the three reasons why it was a better place after Covid-19.

Example: Three reasons why it’s better after Covid-19 is ________.
The three examples I chose were indoor non-essential are opened, gatherings are allowed during events and masks and face coverings are no longer mandatory.

Can you show me a proper way to write the sentence with the examples I choose above because one person said I should tell three reasons why it was better before Covid-19
