Most biologists agree that with extinction rates【C5】______and climate change looming, the【C6】______to document the planet’s biodiversity—or biota (生物区)—is urgent,【C7】______considering the essential role these life forms play in crop pollination, clean air, and other aspects of human【C8】______ "We are losing species by extinction faster than we are describing new species" according to some estimates, says biologist Antonio Marques, who【C9】______ the new paper with Fernando Carbayo, both at the University of St. Paulo in Brazil. "We have to know the biota to preserve and conserve the biota," he says.
