The Guardian: Mexico is facing a "toxic crisis" and has become a "garbage sink" for the US, exposing Mexican communities to dangerous pollution, a UN expert has warned. In an interview with the Guardian and Quinto Elemento Lab, an investigative outlet, Marcos Orellana, an environmental specialist, said pollutants ranging from imported waste to dangerous pesticides were affecting people's right to live healthy lives. Orellana, whose title is UN special rapporteur on toxics and human rights, conducted an 11-day investigative mission in Mexico last month to learn about toxic threats facing its population. He said he found lax environmental standards and a lack of oversight, which have allowed pollution to accumulate over the years.
