The late 91-year-old London, England, native died while on her speaking tour in California. With her death so sudden to mourners, many wondered what happened to her and what her cause of death was. Just one day before Jane died, a video was posted to her institute's Instagram page. In it, she discussed our ecosystem's deterioration. She had also appeared at New York Climate Week less than one week before her death.
