A study suggests that a new level of international coordination is needed to monitor global vegetation and help address many challenges facing the Earth by the growth of what’s being called the “technosphere” – the full impact of human-made objects and their interactions on the planet.  A new system should be set up under the auspices of the United Nations or other organization to accomplish the type of monitoring that is needed, said David Turner, an OSU associate professor of global change biology, in a new publication in Frontiers in Ecology and the Environment.
