July 28th: National & International Days, Celebrations and Observances

July 28 marks diverse action opportunities. Wildlife groups urgently seek aid to shield tigers in their wild territories. Medical professionals stress the value of spreading accurate hepatitis prevention information through social networks.

• Visitors who care for parks and nature areas make a real difference. Parents and mentors deserve more than words - they need genuine acts of thanks. Study the Buffalo Soldiers' achievements, then share these powerful accounts of their service and sacrifice.
• Try this: Pack your camera and explore a local park with your kids. Pause to spot cardinals perching or blue jays darting between trees. When shopping for treats, check chocolate labels - the best companies put money back into saving forests.
• Your neighborhood needs you. Pick up trash at the park, plant native flowers, or team up with local conservation groups. Each action, no matter how modest, shapes our shared spaces.

July 28th marks several turning points in history. Few dates hold such varied significance.

The Australasian Antarctic Expedition set sail in 1911 when the SY Aurora left London. For three grueling years, Sir Douglas Mawson's team worked in Earth's harshest environment.

• They put 2,000 miles of Antarctic coast on the map - no small feat.
• Their lasting legacy includes the first-ever radio link between Antarctica and Australia.
• The team even found time to document every plant and animal on Macquarie Island, something no one had managed before.

The Columbia River kept a secret for thousands of years. In 1996, that changed. Walking near the Washington state shoreline, someone spotted bones jutting from the riverbank. These 8,500-year-old remains - later dubbed Kennewick Man - sparked intense debate about America's earliest inhabitants. By 2015, DNA testing pointed to Native American origins. The Columbia River tribes finally brought their ancestor home in 2017.

Back in 1868, William H. Seward's signature on the 14th Amendment did more than anyone expected. What started as basic citizenship rights grew into something broader. Take Warren County - those constitutional protections helped locals stand up against unfair toxic waste practices. Not bad for a single day's work.

July 28 marks the birth date of five people who changed science and society.

• Jacques Piccard took the submersible Bathyscaphe Trieste to new depths in 1960. He reached 35,814 feet in the Mariana Trench, where his team spotted life moving in the darkness below.
• Beatrix Potter's Peter Rabbit books. Away from her writing desk, she filled notebooks with precise fungi drawings and research. Her 23 children's stories brought success, which she used to save the Lake District. She bought up land piece by piece, protecting thousands of acres from development.
• In 1980, Terry Fox began running across Canada on one leg. Cancer had taken the other, but he pressed on for 5,373 kilometers with a prosthetic limb. Each step inspired more people to join his cause. Annual runs in his name have now raised $850 million toward cancer research.
• Sossina M. Haile tackled problems others thought impossible. The Ethiopian-American scientist found ways to boost fuel cell performance. Her work with sustainable materials brought recognition from the MacArthur Foundation.
• After reaching both poles on foot, Robert Swan turned explorer into educator. He watched Antarctica changing and created the 2041 Foundation. Now he leads trips south, showing others why we must shift to renewable energy sources.
