Won’t Buddhism solve all suffering? Why doesn’t everyone just become a Buddhist and meditate?
Buddhism seeks to end only an individuals suffering by transforming the mind. For example, to get to a place where one doesn't care and doesn't react if they're on fire and burning to death. Spiritually, some say there's a way for individuals to escape reincarnation, usually through extreme tasks.
But this approach still leaves sentient life trapped in a cycle of birth, death, and suffering. Most people can not accomplish this, and no animals can accomplish this. Only the very rare and very practiced monk has been able to get to the point of not suffering in extreme situations. Animals getting eaten alive cannot meditate to get rid of their fear and pain. Neither can a 5 year old child slave meditate while they're being abused. Even if one individual finds peace through this mental method, countless others will continue to suffer, generation after generation.
