The parent premise:

Important to keep in mind that - deep down - maybe no one needs to be converted, just remembered. About the value of nature and biodiversity... about us being nature ... about us not wanting the planet to become a desert...

The type of premise. It can be:
  • but: An objection against the contention.
  • because: A reason for proof the contention.
  • however: An additional situation for the premise.

Example: We define happiness as a state of well-being, starting with being alive instead of dead.

You can also associate your premise with an argument.

Example: Charles Darwin's The Origin of Species
