Describe three ways that biology has impacted the health of people around the world.

 biology affects society in many ways: 
1- It affects the religious believes in society. Some people have become more religious when they saw how our body works while others see that humans are the only Gods on earth 
2- Biology have transformed our world to a more developed world. People know more about their body function and their environment and thus became more educated and developed in the way they handle it 
3- The rise of new bio technologies in society (like IVF) gave rise to new forms of families and relationship. Single mother families can now exist. A mother can go to a sperm bank and get pregnant without the need for a partner
