Observed each year on May 22, International Day for Biological Diversity is a global reminder that life on Earth is richer—and more fragile—than it appears. Established by the United Nations, today highlights why protecting plants, animals, and ecosystems matters for food, medicine, climate stability, and everyday well-being.

International Tea Day celebrates a drink that connects daily rituals to ancient landscapes. Just one look at the terraced tea fields of Sichuan Province, China, shows how deep those roots run. This misty region in southwest China is one of the earliest centers of tea culture, where people drank and cultivated tea more than 2,000 years ago. On nearby Mengding Mountain, a scholar named Wu Lizhen planted some of the world's first managed tea gardens during the Han Dynasty, laying the groundwork for generations of growers.

A soft buzz and a dusting of pollen can shape the future of our food. World Bee Day, observed each year on May 20, celebrates pollinators like the bumble bee pictured here during its quiet yet essential work. Unlike many insects, bumble bees use 'buzz pollination,' vibrating their flight muscles to shake pollen from flowers—a method vital for crops such as tomatoes, peppers, and blueberries.

At Mallorca's far northern tip, in Spain's Balearic Islands, the Formentor Lighthouse stands on the sheer cliffs of Cap de Formentor. This exposed headland is often called the 'Meeting of the Winds.' Built in 1863 and first lit on September 30 of that year, the lighthouse rises nearly 700 feet above the Mediterranean Sea and is reached by a narrow, switchback road about 8 miles from Port de Pollença. Under your feet is pale limestone—rock formed from ancient marine life and later lifted and carved by erosion into dramatic faces, sea caves, and natural arches. This rugged geology gives rise to the area's stark beauty and sense of isolation. Want to earn the view? Follow one of the peninsula's hiking routes, or tackle the short, steep climb to Talaia d'Albercutx for a watchtower panorama before continuing to the lighthouse. Keep an eye on the slopes: wild goats, descended from early domestic herds, spring across the ledges with effortless balance.

You walk into a museum, and suddenly time shifts. A fossil hints at life millions of years ago. A gemstone reflects geological change you can't see. That sense of connection is exactly what International Museum Day, created in 1977 by the International Council of Museums, aims to celebrate.

How high is high enough for a great view? In the eastern United States, it doesn't take much. Hawksbill Mountain is the highest point in Shenandoah National Park, Virginia, at 4,050 feet, showing how these older mountains rely on openness, not elevation. The park's establishment in 1935 involved reforestation after extensive farming and logging. Today, much of that land has returned to forest, supporting mixed hardwoods, mountain laurel, and rhododendron. What else? Some of the rocks found here date back over 1 billion years, among the oldest in the state. The park shelters over 200 bird species and 32 species of fish and remains dog friendly, allowing pets in campgrounds and on most trails.

What do you call a place where the rocks do the climbing, and humans try to keep up? Welcome to Smith Rock State Park in Oregon, where cliffs rise fast, and excuses fall faster. It sits inside the 26-mile-long Crooked River Caldera, shaped by multiple volcanic eruptions. Its welded tuff cliffs are made from compressed volcanic ash that cooled under pressure. The Crooked River carved the canyon, while formations like the Spire rise up to 700 feet.

Brains, brawn, and a serious case of going deep—the sperm whale isn't here for surface-level living. This Endangered Species Day, meet a giant that thinks big and dives deeper.

Perched on a tufa ridge in southern Tuscany, Italy, Pitigliano is a small town with a big personality. Its roots stretch back to Etruscan times, and the winding streets still echo the past, from medieval fortifications to Renaissance palaces. Walking through its narrow alleys, you can feel centuries of life carved into the stone, while small piazzas invite pauses for coffee or gelato. This enduring treasure is often called 'Little Jerusalem' for its historic Jewish quarter, where a synagogue and historic cemetery tell stories of a once-thriving community.

In today's image, the granite arches of the Alabama Hills frame the Milky Way over a rugged landscape in California's eastern Sierra Nevada. Famous for its rounded boulders and weathered rock formations, this area formed when molten rock cooled deep underground around 100 million years ago. Water and wind gradually shaped the stone into the smooth shapes seen today. Visitors can explore the natural arches, hike among the rocks, capture photographs of the unique landscape, ride horses or mountain bikes, and enjoy seasonal displays of wildflowers.

Along the rocky coasts of the North Atlantic, Atlantic puffins make their homes in burrows and cliffside crevices. These seabirds, with their black‑and‑white plumage and colorful beaks, are classified by the IUCN as vulnerable, as overfishing and changing ocean conditions reduce the availability of their prey. Each spring, they return to breed, laying a single egg in carefully dug burrows. Remarkable swimmers, they use their wings to 'fly' underwater when hunting small fish such as herring and sand eels.

One of the world's greatest natural wonders stretches through the turquoise waters of the Coral Sea off Australia's northeast shoreline. The Great Barrier Reef, running along the coast of Queensland, is the world's largest coral reef system. It is made up of nearly 3,000 individual reefs and hundreds of islands, spanning more than 1,400 miles.

On Mother's Day, we honor the care, patience, and protection that shape lives everywhere. In the wild, these qualities often stand out most where survival is hardest. Captured in Wapusk National Park in northern Manitoba, Canada, today's image shows a polar bear mother and her cubs sharing a playful moment on the Arctic tundra.

Water is the architect of Krka National Park in Croatia, shaping emerald pools and layered waterfalls along the Krka River. Today's image highlights Skradinski Buk, the park's most famous waterfall system, where multiple streams spill over travertine terraces in a dense forest near the village of Lozovac.

World Donkey Day celebrates one of humanity's most quietly capable partners. Donkeys have worked alongside people for thousands of years, prized for their endurance, sharp memory, and sure-footed confidence on rugged ground. Often mistaken for stubborn, they are actually careful thinkers—pausing to assess risk rather than rushing into trouble.

Stretching across the Sonoran Desert in southwestern Arizona, Kofa National Wildlife Refuge is a land of sharp peaks, wide skies, and surprising life. The refuge was established in 1939 to protect desert bighorn sheep, whose sure-footed silhouettes still define the rugged landscape.

Located on the eastern Balkan Peninsula, Bulgaria sits at the crossroads of Europe and Asia, where ancient cultures, fertile landscapes, and shifting climates converge.

Cinco de Mayo marks a defining moment in history: on May 5, 1862, a smaller Mexican force defeated the French army at the Battle of Puebla, slowing France's attempt to expand its control over the country. It's not Mexico's Independence Day—that's celebrated in September—but a symbol of resilience that later took on special meaning in the United States, where it grew into a celebration of Mexican heritage and culture.

May the 4th be with you! On Star Wars Day, reality cosplays as science fiction and dares you to tell the difference. Our image takes us to Ksar Ouled Soltane in Tunisia's Tataouine district, where stacked clay granaries rise like sand‑colored fortresses. Dating back to the 15th century, this storehouse complex was built by Berber communities to protect harvests from heat, theft, and time. Function first. Beauty as a side effect.

High above the savanna in Kenya's Masai Mara, a leopard curls up on a tree branch, napping as the grasslands glow at sunset. On International Leopard Day, observed on May 3, we celebrate one of the world's most adaptable big cats. Leopards roam across Africa and parts of Asia, thriving in habitats that range from forests and mountains to open savannas. Their spotted coats are unique to each individual, like fingerprints, and their powerful climbing skills allow them to stash prey high in trees, out of reach of scavengers.

Can you picture more than 4,200 square miles of protected wilderness? That's Jasper National Park in Alberta, Canada. Established in 1907 as part of a growing network of protected landscapes in the Canadian Rockies, it was designated a national park in 1930. The park reflects both conservation efforts and much older Indigenous connections, including those of the Nakoda and Secwépemc peoples. Its terrain ranges from glacier-fed rivers and alpine meadows to dense conifer forests dominated by spruce and pine.

They don't rush—they ripple. Meet the koi, photographed at a Lan Su Chinese Garden pond in Portland, Oregon. In many Asian cultures, these colorful swimmers symbolize patience, perseverance, and transformation. They can live for decades—some reach 25 to 50 years, and others live far longer: one koi named Hanako was reportedly 226 years old.

Imagine a flower sparking a financial frenzy. Sounds unlikely, right? Yet in the 1630s, tulips did exactly that in the Netherlands. During tulip mania, rare bulbs became luxury items traded for astonishing sums—some valued at prices comparable to a house. Why so valuable? Unusual colors and striped patterns were scarce and unpredictable, and collectors wanted the rarest varieties they could find.
