Do you have any justification for that number? Does it bother you that the current population is around 15 times that?

This seems an almost impossible question to answer as I do not know what food production could potentially increase to in the future and there are many limiting factors which would prevent a huge number of people surviving including space to build houses , food , drink , cleanliness, etc theroetically though given an infinite amount of space and resource the human population could unceasingly increase

I have just learnt about neurones. I wonder why neurones have only one axon. Can they transmit nerve impulses faster and more rapidly when they have more axons? Does having more axons help in coordination? Could anyone tell me why neurons have only one axons? Thanks in advance.
