Final answer:
Adolescent pregnancy rates are high due to factors such as societal issues, genetic programming, and lack of comprehensive sex education.
Step-by-step explanation:
Adolescent pregnancy rates are high due to a combination of factors. One factor is the unwillingness of couples to bring children into a world that is currently facing issues such as poverty, violence, and climate change. Another factor is the genetic programming of adolescents to be risk-takers, which can lead to a higher propensity for engaging in risky behaviors such as unprotected sex. Additionally, the lack of comprehensive sex education can contribute to higher teenage pregnancy rates.
