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.

The biodiversity in tropical rain forests is not in their soil, which is often of poor quality, but in their canopy, or layer of overhanging tree branches. The biodiversity of the Amazon rain forest includes hundreds of thousands of insects and plants, some of which have the potential to treat human diseases. Here, and all over the Amazon basin, companies and governments are destroying the rain forest for agriculture, housing, and industry.

Rev. Dr. Martin Luther King, Jr., was pastor at Dexter Avenue Baptist Church in Montgomery, Alabama, from 1954-1960. King helped organize the Montgomery bus boycott from the basement of the church. During the boycott, African Americans refused to ride Montgomery city buses, to protest unequal treatment. The boycott lasted 381 days and when it was over, the U.S. Supreme Court declared segregated bus seating unconstitutional. Ten years later, King walked by his old church during the 1965 Selma to Montgomery march for voting rights. Behind the church stand the high-rise offices of the Southern Poverty Law Center, a major civil rights organization.

In the the Northern Territory of Australia, men dance to the music of a didgeridoo. The didgeridoo player uses a technique called "circular breathing" when playing the instrument. "Circular breathing" is a technique in which air is inhaled through the nose while being exhaled through the mouth at the same time. This technique allows the player to make a continuous sound without stopping to breathe. Didgeridoos were invented in northern Australia, and are played during cultural ceremonies and rituals, as well as for recreation and entertainment. Didgeridoos have become popular throughout the world as a musical instrument.

February 1, 2010—Two sets of human-made islands lie off the coast of Dubai in a new astronaut's-eye view of the United Arab Emirates metropolis. The Palm Jumeirah (left) required more than 1.7 billion cubic feet (50 million cubic meters) of dredged sand to create the palm tree-shaped island. The 300 islands that make up "the World" meanwhile, required 11.3 billion cubic feet (320 million cubic meters) of sand, along with 37 million tons of rock for the surrounding 16.7-mile-long (27-kilometer-long) breakwater.The recently released snapshot, taken from aboard the International Space Station, also caught the spiky shadow of the world's tallest building, the 2,600-foot-high (800-meter-high) Burj Khalifa, near the lower right edge of the frame.

"What I like to tell kids is that 3,000 years ago, 4,000 years ago and even 5,000 years ago people were just as interconnected as we are today," says National Geographic Archaeology Fellow Fredrik Hiebert. Artifacts from the past also connect to the present. The balanced shape of this amphora (an ancient vase) gives archaeologists like Hiebert evidence that ancient Egyptians were adept at forming sophisticated pottery without pottery wheels.
