Holdridge life zones – Wikipedia . Excerpt . Climate change Many areas of the globe are expected to see substantial changes in their Holdridge life zone type as the result of climate change , with more severe change resulting in more remarkable shifts in a geologically rapid time span, leaving less time for humans and biomes to adjust. If species fail to adapt to these changes, they would ultimately go extinct: the scale of future change also determines the extent of extinction risk from climate change . For humanity, this phenomenon has particularly important implications for agriculture , as shifts in life zones happening in a matter of decades inherently result in unstable weather conditions compared to what that area had experienced throughout human history. Developed regions may be able to adjust to that, but those with fewer resources are less likely to do so.
