South Korea rebuilt forest cover from near-total collapse in 1955 to roughly 63 percent of national land today, through an 11-billion-tree state programme launched in 1973 and a nationwide switch from firewood to coal briquettes.
In September 1859, the largest geomagnetic storm on record induced currents so strong in North American telegraph lines that operators pulled their batteries and kept transmitting on solar-driven current alone, while red auroras were reported as far south as Havana.
In 1994 a parks officer abseiled into a sandstone canyon northwest of Sydney and found a stand of conifers matching a 90-million-year-old fossil pollen record. The Wollemi pine, down to fewer than 100 adults, has been protected by classified coordinates, helicopter access and a 2019 firefighting operation that saved every mature tree.
