What are Old Growth Forests?
We all know that forests are necessary to preserve environment. But there is some specialty to old growth forests when compared to normal forests. Old Growth forests are those which have not undergone unnatural changes since a couple of centuries.
Old growth forests (150-500 yrs) mean forest which grew up without support of human beings in natural environment since hundreds of years. We can see diversity of various living things in these forests. These forests are home for rare species, endangered species. These forests absorb poison gases many times more than other forests from atmosphere and store them. If we damage these forests that poisonous gases are released to atmosphere. Even though these trees are planted again, they take 150- 500 years to absorb poisonous gases like old growth trees. So it is necessary to protect old growth forests.
