Although there's four months left of 2014, humans have already exhausted the ecological space for this year. This means that there has been more consumption of resources than the planet can handle, and over-consumption is only getting worse, according to researchers.
Demand for renewable ecological resources and the services they provide is now equivalent to that of more than 1.5 Earths. This is the conclusion drawn by the researchers from the think tank Global Footprint Network, who calculated how much of the ecological resources have been spent. It's about things like soils, fish, forests, clean water and climate change.
