The best way for humans to have any real knowledge or appreciation of such rain forests is to visit them, to put on hiking boots and walk softly amongst their quiet happenings, preferably in all seasons. The magnificent trees suck in that worrisome carbon dioxide, use solar energy to power growth, and throw away oxygen.
Lungs breathe easily and safely in the unpolluted air.
Trees creak in the gentle wind. Mushrooms grow under sheltering trees from spores that squirrels and mice have inadvertently planted. Below ground, a mutually beneficial exchange occurs between the entanglement of tree roots and these fungi. High in the forest canopy, lichens pull nitrogen from the atmosphere and drop it as fertilizer. Leaves form cups for holding water.
