                                United in Desire
                                THERE IS A MORBID THRILL in searching for the last of something. I considered this while looking for the critically endangered cactus Uebelmannia buiningii among the quartz hills of the Serra Negra in Minas Gerais, Brazil. Uebelmannia is a small genus of Brazilian cactus described by Dutch botanist Alfred Buining. The genus is named for the Swiss cactus collector and former race car driver Werner J. Uebelmann, a lifelong collector, nurseryman, and devotee of Brazilian cacti. These Eurocentric tendencies in species naming are common in botany, a field whose entwinement with settler colonialism and imperialism runs deep.

                                I was travelling with a group of self-described European “cactoexplorers” for several weeks through the states of Minas Gerais and Bahia, Brazil, a region with some of the highest cactus species richness and endemism in the world. I was invited to join the search as part of the research for my book on the global illicit trade in cactus and succulent plants.

                                Thanks to our guide, an expert Brazilian botanist, we were equipped with the precise coordinates of one of the few known locations of U. buiningii, so our prospects for seeing it were high.

                                Unlike other species I had already encountered in Brazil, U. buiningii isn’t primarily threatened by farmland development or urbanization. According to species experts it is threatened above all by illegal collection for international trade. U. buiningii’s habitat is restricted to an area of less than 40 square kilometers, with just a few small and isolated subpopulations remaining. The type locality for the species, or the location where a plant was first taken and used to formally describe the species on an archived herbarium sheet, is now absent any remaining plants.

                                Political ecologist Jared Margulies takes readers inside the intriguing world of cactoexploring and unravels the similar passions that animate both illicit cacti collectors and conservationists in our Autumn 2023 print issue cover story.

                                Action on the climate crisis may not be the first thing that most people associate with hip-hop, but the musical genre has long been calling attention to environmental injustice. (Grist)  

                                Orange is the New Healthy?
                                Eggs with shockingly orange yolks have infiltrated America’s supermarket shelves, boasting virtue and vitamins. But do they really provide the touted nutrition benefits, or are we paying a premium for the simulacra of “all-natural”? (Eater)

                                One crafter set out to sew a plastic-free, non-toxic stuffed whale for a friend’s newborn. Simple enough, right? Turns out, making a fully-compostable, huggable toy for our babes is a nearly impossible task. (Environmental Health News)

                                Among the many preconditions that can put people at heightened risk from extreme heat, one stands out as potentially the most dangerous of all: Schizophrenia. Why would a mental illness make you more vulnerable to heat? A journalist’s quest to understand this question led her to a young Phoenix resident, Stephan Goodwin. (Washington Post)
