November 24th: National & International Days, Celebrations and Observances

November 24th offers simple ways to create real change.

• Post facts about local sea life on your social media - even small efforts help spread marine awareness.
• Between bites at Thanksgiving dinner, mention the wild things growing in your backyard.
• Support Mediterranean conservation groups if you can, or cook a few regional specialties that go easy on ocean resources.
• Break out some science games after dinner. The whole family might enjoy learning about evolution.
• Check labels for sustainable sardines next time you shop. Talk about smart fishing while you're at it.
• Let kids explore outdoors - they'll spot the same patterns Darwin noticed on his walks.

Got a knack for science? Start tracking neighborhood wildlife and weather changes. Local researchers need everyday people to help count animals. Every observation counts.

Significant dates often tell unexpected tales. Take November 24th - a day linking far-flung shores, a beloved book, and footprints on the moon.

• Back in 1642, Abel Tasman's crew spotted unfamiliar coastlines. What they found became Tasmania, though it kept its original name - Anthony van Diemen's Land - until 1856. Nature took its time here. Some Huon Pines have stood watch for over 2,000 years. The isolation worked wonders: 33 types of mammals evolved here, along with 12 bird species you won't find anywhere else.
• The story shifts to London, 1877. That's when Anna Sewell finished "Black Beauty." Within two years, 30,000 readers had her book in their hands. More importantly, those pages pushed lawmakers to strengthen animal protection. Sewell died just five months after publication, but not before seeing her words make a difference. Today, over 50 million people know Black Beauty's tale.
• Last but hardly least - Apollo 12 splashed down in '69. The crew didn't come back empty-handed: 75 pounds of moon rocks made the journey home. Between setting up the first proper lunar science station and snapping more than 2,000 photos, they left their mark on space research. Each rock, each image added another piece to our moon puzzle.

Four revolutionaries - all born on November 24th - left lasting marks on our cities and wild spaces. Take Walter Burley Griffin: born in 1876 Chicago, he rejected standard city grids. His fresh thinking earned him the contest to design Australia's capital. The suburb of Castlecrag in Sydney still shows his talent for weaving buildings into raw bushland.

Most geologists in the 1920s were men. Not that this stopped Esther Applin. Between 1895 and 1972, she mapped the Gulf Coast through microscopic fossils called Foraminifera. Her expertise ran so deep that in 1950, the Society of Economic Paleontologists and Mineralogists did something unprecedented - they elected their first woman president.

After winning the Booker Prize, Arundhati Roy could have stuck to fiction. Instead, this writer born in 1961 turned to environmental battles. She documents how massive dams force villagers from their homes and destroy ancient forests.

Dr. Mona Hanna-Attisha spotted trouble in Flint's water during 2015. Her tests showed alarming lead levels in children. When officials dragged their feet, her research forced action. Now she works beyond Flint, protecting families nationwide from water contamination.
