Some things that these trees have to offer are fruit, oxeygen, leaves that could be used in herbal medicine, and many other things. As you may know, they release oxeygen through their leaves. This could help with air pollution and provides 30% of the world's air.
What they Provide
Even though it's not good to remove trees from forests, people cut these trees for a reason.
For most of human history, deforestation in the Amazon was mostly the product of farmers who cut down trees to produce crops for their families and local use . That changed later in the 20th century, almost 3/4 of forest clearing was because of cattleranching. Also, they were cut for cattle pasture and soy farms, drowned for dams, dug up for minerals, and bulldozed for towns and colonization projects.
Also, the building of roads opened previously inaccessible forests to settlement by poor farmers, illegal logging, and land speculators.
