Same problems: These two Sharon McAuliffes don't really look all that much alike, and while Christa McAuliffe (she went by her middle name rather than "Sharon") the schoolteacher was obtaining degrees in education from Framingham State College (Massachusetts) and Bowie State University (Maryland), teaching social studies at Concord High School (New Hampshire), and training with NASA, Sharon McAuliffe the lawyer was attending Syracuse University and working for an accounting firm in Syracuse (New York).

Caledonian pines and Coniferous trees such as Scots Pines: these are brilliant for creating sheltered areas on your farm, especially useful during the colder months.

A 10 year transition to agroecology

Willow trees: These have loads of health benefits for cattle, in part due to the salicylic acid they contain, which helps give animals healthy skin and hair. Willow trees also contain a natural pain-reliever, which means our cows can self-medicate when needed by chomping on their leaves Yes, the late Ronald McNair looked a lot like his brother, Carl, as many siblings do (but they're still easy to tell apart, as Carl has an obvious gap in his front teeth that Ronald didn't). And this proves what, exactly? It might be a curiosity if there were no record of the existence of "Carl McNair" until after the Challenger explosion, but that isn't the case. Are we supposed to believe that Ronald secretly took over his brother's identity after the Challenger "accident" and somehow engineered the disappearance of the real Carl? Of course, the real point of this comparison is that the creators of this conspiracy theory couldn't find a similarly named doppelgänger for Ronald McNair other than his own brother. Silvopasture gives cows choice in where to be and what to eat, which Karolini Tenffen de Sousa, a postdoctoral fellow at Instituto de Zootecnia in Brazil who specializes in cattle behavior, says can improve their health. Cows can be in the shade when they want, drink water when they want, and graze when they want. “If they don’t experience stress their physiology will be good,” she said. Still, the technique is gaining popularity. Chedzoy has been encouraged by the increasing popularity of his courses and trainings and by young farmers following in his footsteps who are committed to regenerating their land with agroforestry.

These thriving intersections – a favourite for birds, insects and mammals (such as pine martens and foxes) alike – are: Silvopasture is a type of agroforestry, or agricultural forestry, where cows graze within wooded areas, eating invasive plants and helping to restore forests. It also allows farmers to simultaneously raise cattle and grow marketable timber. Keyes and Keyes call the practice an “economic opportunity” that could lead to more diverse forests and healthier cows. Considered better for the environment and less emissions-intensive than most other forms of cattle production, silvopasture is seeing a resurgence around the world with major efforts to expand its usage in Canada, Brazil and the Mediterranean. And now, in part through Chedzoy’s work, in the US as well. According to a 2017 study from the Center for Agroforestry at the University of Missouri, silvopasture can also extend the grazing season, so that it starts earlier in spring and lasts longer in fall compared to open pasture. Forage also grows better in silvopastures during the hottest times of the summer compared to open pasture, the study found.And silvopasture allows for many layers of biodiversity compared to grasslands. They support a wider variety of bird species, more pollinators, bigger and more diverse mammals, and a much wider variety of plant life with more varied root systems.
