I believe in praying as i know when i myself can not do so much to change so much, by praying God lifts up other like minded and together we can do it, that's how prayer works. By praying God gives us wisdom and discernment which many lack. I won't stop praying because i know on our own thinking, might,wisdom and power without Jesus Christ at the lead we are bound to crumble. Look at the old testament, the books of judges, kings and chronicles, kingdoms that left God out of their plans crumbled, those that acknowledged God survived.
