Why is biological knowledge necessary for every educated person?

I believe that every person needs to have at least a basic knowledge of biology.

This knowledge can help him provide first aid, because biology is the basis of medicine.

If a person knows biology, then the chances of being poisoned by an inedible plant or fungus are significantly reduced.

A person with biological knowledge will be able to distinguish a poisonous snake from a non-venomous one, a rabid animal from a healthy one, a syndrome of a serious illness from a common allergy.

Everyone should know the basics of this science, at least in order to protect themselves and make their life easier.
