Why are scientists concerned about deforestation (the clearing of trees)? how is the conservation of habitats related to the work a taxonomist does?

Scientists have become concerned about deforestation due to its rapid increase in the last decade wherein more and more species are declining due to their habitat and food sources being destroyed. Taxonomists who study primarily in plant and animal groups are also concerned at how this will affect specific species of flora and fauna in effected areas.
