What’s the question please? I’d like to answer but I’m a bit confused
It’s answer C because of eutrophication
Cons:
It kills animals
It destroys land and trees
It ruins animals homes
Pros
It clears up lane so we can build
Some rare animals need fire to reduce overhanging plants to live ( it’s called a karner blue Caterpillar btw)
And fire is a natural phenomenon that nature has evolved with
I believe it's oxygenated or oxygen rich blood away from the heart.
