Is it necessary for me & my native people to have a religion?

I get where you are coming from. But religion is more than what you are talking about. it is protection and salvation from harm. sometimes God has to take you through bad time to bring you closer to him. and the christians are not doing bad. They are making a living. yes, i hate that we are harming our world. but we have to for survival. and about the head scarves. the schools i go to do accept it. but the ones who do imply that rule, use it for protection. do you know how many things can be hid in a hood and or head scarves. and about your native clothing. i really don't see a problem about it. adam and eve were naked at first till adam ate the apple. you are not purposely doing one of the things that was mentioned in the bible. but i think the reason most places wont accept it is for respect and conservation.
