않는다면
"않는다면" means "if (someone/something) does not."
In this sentence, '않는다면' is used after the verb '공부하다' (to study) in its negative form ('공부하지 않다') to express a conditional situation that leads to a consequence.
열심히 공부하지 않는다면 시험에 합격하기 어려울 것입니다.
If you do not study hard, it will be difficult to pass the exam.
Here, '않는다면' follows the verb '이해하다' (to understand) in a negative form ('이해하지 않다'), conveying a hypothetical situation where lack of understanding might lead to an undesired outcome.
우리가 서로를 이해하지 않는다면 갈등이 생길 수 있습니다.
If we do not understand each other, conflicts may arise.
In this example, '않는다면' is attached to '보호하다' (to protect) as '보호하지 않다' to present a conditional scenario involving environmental conservation and its importance for future safety.
