An investigation reveals that US companies export over a million tons of hazardous waste annually, primarily to Mexico and Canada, raising concerns over health and environmental impacts. Since 2018, these exports have increased by 17%. In Mexico, recycling plants near Monterrey have reported high toxins like lead and cadmium affecting local communities. In Canada, waste processing near populated areas has led to elevated arsenic levels. Experts highlight weak regulatory oversight in receiving countries, allowing US companies to bypass stringent domestic rules. The concept of "waste colonialism," where richer countries dump toxic materials on less affluent nations, exacerbates environmental injustice.
