Ukrainians jump over a bonfire in Kiev, Ukraine, 06 July 2019, as they celebrate the traditional pagan holiday of Ivana Kupala. Ivana Kupala is celebrated, during the summer solstice, on the shortest night of the year, marking the beginning of summer and is celebrated in Ukraine, Belarus, Poland and Russia. People sing and dance around bonfires, play games and perform traditional rituals. Young people jump over bonfires in order to test their bravery. Couples holding hands jump over the flames to test their love. If the couple does not succeed it is predicted to split up. Traditionally, children and young unmarried women wear wreaths of wild flowers on their heads to symbolize purity. (Photo by Sergey Dolzhenko/EPA/EFE)

Renee LeGrand, of Foothill Ranch, Calif., takes a picture among wildflowers in bloom Monday, March 18, 2019, in Lake Elsinore, Calif. About 150,000 people flocked over the weekend to see this year's rain-fed flaming orange patches of poppies lighting up the hillsides near Lake Elsinore, a city of about 60,000 residents. The crowds became so bad Sunday that Lake Elsinore officials closed access to poppy-blanketed Walker Canyon. By Monday the #poppyshutdown announced by the city on Twitter was over and the road to the canyon was re-opened. (Photo by Gregory Bull/AP Photo)

Clinging on with sticky toes, a green tree frog sits bravely on its unlikely friend – a large tree python. Curled around the branches of a small coconut tree, the snake appears relatively undisturbed by the bold passenger that has clambered onto its skin. Grown in captivity together, the pair display no signs of aggression or fear, comfortable with their encounters high up in the leafy branches. Photo enthusiast Fahmi Bhs watched in surprise as the frog slowly climbed along the scales of the metre long snake in a zoo in Jakarta, Indonesia. (Photo by Fahmi Bhs/Solent News/SIPA Press)

People release floating lanterns during the festival of Yee Peng in the northern capital of Chiang Mai, Thailand November 14, 2016. Yi Peng refers to the full moon day in the second month according to the Lanna lunar calendar (the twelfth month according to the Thai lunar calendar). Swarms of Lanna-style sky lanterns are launched into the air where they resemble large shoals of giant fluorescent jellyfish gracefully floating through the sky. The festival is meant as a time for tham bun, to make merit. Khom loi are made from a thin fabric, such as rice paper, stretched over a bamboo or wire frame, to which a candle or fuel cell is attached. When the fuel cell is lit, the resulting hot air is trapped inside the lantern and creates enough lift for the khom loi to float up into the sky. (Photo by Athit Perawongmetha/Reuters)

Two boys in the Gorbals area of Glasgow, UK on January 31, 1948. The Gorbals tenements were built quickly and cheaply in the 1840s, providing housing for Glasgow's burgeoning population of industrial workers. Conditions were appalling; overcrowding was standard and sewage and water facilities inadequate. The tenements housed about 40,000 people with up to eight family members sharing a single room, 30 residents sharing a toilet and 40 sharing a tap. By the time this photograph was taken 850 tenements had been demolished since 1920. Redevelopment of the area began in the late 1950s and the tenements were replaced with a modern tower block complex in the sixties. (Photo by Bert Hardy/Getty Images)
