Water companies have come under fire in recent years for allowing more frequent discharging of sewage spills, polluting rivers and lakes.

Particle pollution metrics told a similar story, where Los Angeles saw improvement but still had the dubious honor of being the nation’s seventh-most polluted city by that measure.

The city’s growth has far outpaced the existing sewage treatment plants, and inadequate and broken facilities spew waste into the river, polluting the water and air in Imperial Beach and other communities near the border.

Both the extraction and processing of these rare earths are costly and polluting.

The UK government ban on disposable and single-use vapes is aimed at stopping littering as, in most cases, the vapes cannot be recycled and often end up in landfill or pollute natural environments.
