A waste picker unloads garbage at a waste transfer station in Bamako, Mali, August 19, 2018. In the Malian capital of Bamako, donkey carts driven by young men like 19-year-old Arouna Diabate play a vital role battling the fast-growing city's waste problem. Every morning before dawn, Diabate hitches his donkey to a cart and sets off on his rounds, going door-to-door to collect household garbage which he delivers to a local waste transfer station for a monthly salary of around $35. “I won't be picking up trash with a donkey cart for the rest of my life, but for now people appreciate us because we help clean up the homes of Bamako”, Diabate said.

For 20 years, Joann Biondi worked as a freelance writer. Then one day she adopted a kitten that had been tossed in a garbage can and left for dead. That kitten had an unusual quirk; he liked to wear clothes and pose for the camera. So Joann started shooting, and then she got serious about photography. Fast forward four years and that kitten is now Lorenzo the Cat, a feline art photography project that has gotten both the cat and the photographer a lot of attention; gallery shows, museum exhibits, and stories in major media outlets throughout the world. Amid it all Lorenzo has remained a mellow dude who still likes to roll around in the dirt, chase lizards, and knock things off the kitchen counter when his food bowl is empty.

Thus, the science of horology can into being, as people invented more and more sophisticated ways of measuring the passage of time. Truly, it’s one of the most profound characteristics of being a human, to feel and to ponder the meaning of time, its properties, and will we ever be able to move through it, not with it. Now, however, horology is mainly referred to the art of mechanical watchmaking. (Photo by MB&F)
