We humans are also dependent on the system for our existence. e.g. we depends on trees for fresh oxygen, we depends on river for drinking water, we depend on soil that produces our food. The forest and tree cover in the country is 23.81 % of the total geographical area out of which dense forests covers 12.24%, open forests covers 8.99% and mangrove forests covers 0.14%.
