Zebras are black animals with white stripes. This striking coloration is probably a form of camouflage. It helps zebras blend into the shadows of tall grasses. It also helps them blend in when they are in a herd. When clustered together, it is nearly impossible to tell one zebra from another, making it difficult for predators such as lions to stalk an individual animal.

The acqua alta, or high tide, floods the Piazza San Marco, Venice, Italy. The aqua alta is usually most pronounced between autumn and spring. Like all tides, the aqua alta is governed by the gravitational pull of the moon. In addition, local wind patterns (called the sirocco and the bora) augment the tide.

Bees are pollen gatherers and pollinators. There are more than 20,000 species. Most are solitary, meaning they live in small groups with a single breeding female and her offspring. Pollen is gathered to feed the young; sometimes it is mixed with nectar to make a paste.

Seas have an enormous impact on the people who live near them. The Bay of Bengal, the largest bay in the world, is a sea that is part of the northeastern Indian Ocean. This sea has played a pivotal role in the histories of the nations that surround it, including India, Bangladesh, Myanmar, and Indonesia. Here, Hindu pilgrims bathe where the sacred Ganges River empties into the Bay of Bengal.

In addition to pastoralists and farmers, Martins works to educate students and guides on the importance of Africa's insect pollinators. In 2011, Martins spent time training guides at the exclusive Grumeti reserve in Serengeti National Park, Tanzania. Here, a guide named Mishi meets a blister beetle. The orange coloring alerts predators to the beetle's stinging, toxic secretion. The secretion is valuable, however—a variation is used to treat warts.

Much of the locavore movement is centered around farmers' markets, like this one in Hudson, Ohio. At farmers' markets, farmers and local food retailers can sell their fresh produce directly to buyers. The goods at farmers markets and community-supported agriculture (CSA) programs are largely determined by the season and weather of the region.

Sphagnum moss is the most common bog plant. This tiny plant stretches across poorly drained ponds, eventually choking them and forming a thick mat across the surface. Other low-lying bog plants include heather, reeds, and sedges.

Sea level is the base level for measuring elevation and depth on Earth. These hotel bungalows in Bora Bora, French Polynesia, have stilts to take them inches above sea level. Because the ocean is one continuous body of water, its surface tends to seek the same level throughout the world. However, winds, ocean currents, river discharges, and variations in gravity and temperature prevent "sea level" from being truly level.

A Geiger counter measures radiation outside the Chernobyl (Ukraine) Nuclear Power Plant, which exploded in 1986. The explosion created a cloud of radioactive particles that fell to the ground, called fallout. The fallout drifted with the wind and entered the water cycle as rain. Radioactivity traced to Chernobyl fell as far away as Scotland and Ireland, although most fallout was detected in Belarus.
