Not just semantics: CO2 fertilization can be a disturbance leading to worldwide forest degradation
The physiological effects of increased atmospheric CO2 (CO2 fertilization) on intact forests are generally seen as a process that might buffer them against the impacts of climate change. However, CO2 fertilization can also cause adverse changes in forest conditions, such as alterations in species composition and reduced ecosystem moisture availability.

Ability of new protected areas to counteract losses from downgrading, downsizing, and degazettement
Abstract Protected area downgrading, downsizing, and degazettement (PADDD) is a common occurrence. Although PADDD is expected to weaken biodiversity protection, PADDD offsets and new unrelated protected areas (PAs) could help restore representation of biodiversity features to the reserve network affected by PADDD.
