[Grammar] about the use of 'not only ~ but also'

[bustler]

Hello!

It is very hard for me as a EFL teacher to use the form "not only ~ but also ~"


Protection of biological diversity targets not only the goal of conserving natural resources but also of preserving people's livelihoods.

Protection of biological diversity targets the goal not only of conserving natural resources but also of preserving people's livelihoods.


Which one is better? or Any other suggestion?

Thank you for your kind answer in advance.

The second.

Thank you.

For your short but enough answer.

Whatever comes after "but also" must be exactly parallel to what came after the "not only."

not only the goal of conserving natural resources but also of preserving people's livelihoods. You see that "the goal" comes after "not only" but it's missing in the second part.

These two would work:
not only the goal of conserving natural resources but also the goal of preserving people's livelihoods.
not only the goal of conserving natural resources but also that [a pronoun standing in for "the goal"] of preserving people's livelihoods.
