I made a comment re plants in their role of air purifiers on here I think but the thread seems to have disappeared , it may have strayed into anti-vax territory I expect, but a few interesting things to consider re rainforest removal besides the air purifying effects of all the plant life, many creatures will suddenly be displaced and take any diseases they have to other places, below is a link on indoor plants.
Not just plants though as I know creatures in seas such as mussels and oysters filter masses of water each day.
