In the 1950s Torreya taxifolia, a type of evergreen tree once very common in the state of Florida, started to die out. No one is sure exactly what caused the decline, but chances are good that if nothing is done, Torreya will soon become extinct. Experts are considering three ways to address the decline of Torreya.
The first option is to reestablish Torreya in the same location in which it thrived for thousands of years. Torreya used to be found in abundance in the northern part of Florida, which has a specific microclimate. A microclimate exists when weather conditions inside a relatively small area differ from the region of which that area is a part. Northern Florida’s microclimate is very favorable to Torreya’s growth. This microclimate is wetter and cooler than the surrounding region’s relatively dry, warm climate. Scientists have been working to plant Torreya seeds in the coolest, dampest areas of the microclimate.
The second option is to move Torreya to an entirely different location, far from its Florida microclimate. Torreya seeds and saplings have been successfully planted and grown in forests further north, where the temperature is significantly cooler. Some scientists believe that Torreya probably thrived in areas much further north in the distant past, so by relocating it now, in a process known as assisted migration, humans would simply be helping Torreya return to an environment that is more suited to its survival.
The third option is to preserve Torreya in research centers. Seeds and saplings can be moved from the wild and preserved in a closely monitored environment where it will be easier for scientists both to protect the species and to conduct research on Torreya. This research can then be used to ensure the continued survival of the species.

Professor Diaz:
This week we talked about how important taking time off from work or school is for people’s well-being. Some people believe they get the most benefit when that time off is structured: that is it involves planning in advance about what will be accomplished on that day. Others believe it is better to enjoy the day with no plan for how to spend it. In this discussion post please indicate which of those approaches to spending time off from work on school you prefer and why?
Claire:
I find it beneficial to do some advance planning for my free time. I live far away from my family so when I am getting ready to visit them during a school holiday, I always plan my time off from school very carefully. That way l have enough time to visit with each family member.
Paul:
Personally, I prefer not to make any plans for my free time. I go to school, and I have a part-time job each week. I make a schedule to be sure I can complete both my work and studies. So when I have time off from work and school, I just want to relax with no plan.
