"Global Concern: Millions Exposed to Arsenic in Drinking Water"

Tens of millions of people in countries like Bangladesh, India, the US, and others are affected by arsenic-contaminated water, a result of well-intentioned public health efforts in the 1970s. Arsenic, a stealth killer, has been linked to a range of health issues and is difficult to detect without testing. The impacts of climate change, such as flooding and sea level rise, are exacerbating the problem by changing the chemistry of groundwater, pushing up arsenic levels. Despite efforts to tackle the contamination, the poisonous impacts are still widespread, and the situation could worsen. The stakes are getting higher as humans continue to burn planet-heating fossil fuels, which could change the parameters of this experiment with disastrous effect.
