In Nairobi this month, the world’s governments will discuss the path towards the first global treaty to tackle plastic pollution. But with multiple proposals on the table, the scope and ambition of a potential treaty hangs in the balance.

“The COVID-19 pandemic has amplified pre-existing inequalities and vulnerabilities,” writes the United Nations Population Fund (UNFPA) in a recent report on the impact of COVID-19 on sex workers in East and Southern Africa. The pandemic has had an impact on people in marginalized communities around the world, but for sex workers globally, “the impact on livelihoods, human rights and health has been devastating, leaving many struggling to survive,” states the report.

As northeast China freezes with the onset of winter, cranes fly south to Poyang Lake, China’s largest freshwater wetland sanctuary, along with hundreds of thousands of migratory wildfowl. For birds that feed on tubers of submerged aquatic plants, such as the critically endangered Siberian Crane, the threatened and declining Swan Goose, and thousands of Tundra Swans, Poyang’s food-rich winter wetlands are key to their survival. However, dams along the Yangtze River and growing floods are disturbing the natural rise and fall of water levels that are needed for Poyang’s aquatic plants to thrive. Poorly regulated and expanding sand dredging in the Yangtze River and Poyang Lake is increasing turbulence in the water, limiting light reaching the aquatic plants that migratory birds rely on. 

Evidence shows that in low- and middle-income countries, the expansion of health coverage or access to care has not always reduced overall mortality, said Dr. Patricia Jodrey, Child Health Team Lead in the Office of Maternal and Child Health and Nutrition at the U.S. Agency for International Development (USAID). “However, the analysis also showed that when countries have progressed in improving the quality of their health systems, the survival rate tends to improve,” she said.

Growing up in Austria in the 1990s, one of the underlying lessons I learned in middle school was that nuclear power is humanity’s downfall. Though never explicitly described that way in the curriculum, from a young age my peers and I knew to associate the black-and-yellow trefoil symbol with apocalyptic environmental destruction. Reflecting on my upbringing helps me understand why so many in Germany, Austria, Denmark, Greece, and Italy argue that nuclear power should be our last resort as an energy resource. How could we allow the development and use of such dangerous technologies in our own lives? How could we just move on and accept that a nuclear accident could kill all of us at any moment?  

Water provision is “more lucrative than drugs,” said one of the interviewees in our research in Karachi, Pakistan. Competition for control of the city’s water includes water mafias and formal institutions. As water becomes increasingly scarce due to ongoing climate changes in the Indus Basin, it is already a source of intense economic and political competition. If not addressed in time, water scarcity may deepen fault lines in this highly fractured, multi-ethnic, populous city.  

As the novel COVID-19 coronavirus swept the planet in early 2020, researchers scrambled to find effective treatments and vaccines. Within a year, there was a clarion call from heads of state, the World Health Organization (WHO) and other agencies to create an international “pandemic preparedness and response” treaty. WHO noted that COVID-19 offered “a stark and painful reminder that nobody is safe until everyone is safe” from zoonotic disease outbreaks.

“The pandemic and related global economic recession are severe setbacks to already insufficient progress towards meeting the global nutrition targets set for 2025 for stunting, wasting, maternal anemia and breastfeeding,” write the authors of a 2021 study examining the effects of COVID-19 on child and maternal health and nutrition. Adequate nutrition in the perinatal period is essential for healthy mothers and babies, and COVID-19-induced poverty and disruptions to global supply chains have compromised the food security of people around the world, mostly in low-to-middle-income countries (LMICs).
