Newbold and co-workers have compiled data about biodiversity loss from across the globe. The question is whether the planetary boundary has been transgressed already. They estimate that the loss of biodiversity on 58% of the land surface on earth is more than can be considered safe. If unchecked, this will make it difficult to reach long-term sustainable development goals. Authors conclude with the following: "Slowing or reversing the global loss of local biodiversity will require preserving the remaining areas of natu- ral (primary) vegetation and, so far as possible, restoring human-used lands to natural (secondary) vegetation".
