The Dangers of Trees

Trees can pose unexpected dangers, with incidents of people getting killed by falling fruits like durians and pine cones. Mary Roach, a science writer, explores the concept of 'danger trees,' which are old, large trees that can unexpectedly fall due to rot. Tree assessors monitor these trees, like in Cathedral Grove, to prevent casualties by either taking action or explosively removing the top parts to reduce risks.
