Answer:

You can read me both ways I wear; One way it's a number reversed a snare.
I'm blue, but when you see me I'm red. You don't see me too often. I'm there for you if you're hurt, but I'm good for you. What am I?
I run through hills. I veer around mountains. I leap over rivers. And crawl through the forests. Step out your door to find me.
What do you call a pig that is no fun to be around?
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
