Question

Explain one positive and one negative effect of technology on health.

Answer 1

The question is kind of ambiguous (what kind of technology) but here goes:
Pro: we can sustain life (through life support) to give the body support so it can heal and recover, meaning we lose fewer lives. We also have the power to essentially resurrect the recently deceased through CPR and similar advances, which means we are saving lives. 
Con: We're playing God and intervening on the process of natural selection (where the weak and sick die off) which means as a human race we become weaker and less healthy, and therefore more dependent on technology.
